Why Choose Rotary Vane Vacuum Pump is Not Ideal for Pumping Speed > 200 m³/h

When your application requires a pumping speed greater than 200 m³/h, it's time to reconsider if a rotary vane vacuum pump is the right choice. Although the rotary vane vacuum pump is a widely used and reliable option in many industries, there are several reasons why it may not be the best choice for higher pumping speeds. In this article, we'll explore the limitations of rotary vane vacuum pumps in high-capacity applications and recommend alternative solutions like Roots vacuum pumps and screw vacuum pumps that are better suited for these demands.

The Limitations of Rotary Vane Vacuum Pumps at High Pumping Speeds

Increased Mechanical Complexity and Maintenance Requirements: As the pumping speed increases, the size and complexity of a rotary vane vacuum pump must also increase. Larger vanes and rotors are required to maintain the higher flow rate, resulting in a heavier and more intricate design. This increase in mechanical complexity leads to higher maintenance demands, with more frequent service intervals and the potential for increased wear and tear on components. In turn, this drives up both the operational and maintenance costs.

Efficiency Drops and Higher Energy Consumption: Rotary vane vacuum pumps operate efficiently within a certain range of speeds. However, when the required pumping speed exceeds 200 m³/h, the efficiency of these pumps tends to decrease. To maintain such high speeds, the pump must operate at higher rotational speeds, which results in significantly increased energy consumption. This inefficiency not only raises energy costs but also makes the rotary vane pump less competitive when compared to other pump technologies better suited to high flow rates.

Temperature Control and Heat Dissipation Challenges: The mechanical action within a rotary vane vacuum pump generates heat, and at higher pumping speeds, this heat can become excessive. Managing this heat effectively is critical to ensuring the pump's longevity and reliability. However, at pumping speeds above 200 m³/h, the ability to dissipate heat adequately becomes a challenge. This can lead to overheating, increased wear on internal components, and potentially, pump failure. These risks make the rotary vane vacuum pump a less reliable option for high-speed applications.

Oil Consumption and Contamination Risks: Rotary vane vacuum pumps rely on oil for lubrication and sealing. As the pumping speed increases, so does the consumption of oil. Additionally, the higher operating speeds can lead to greater oil mist generation, which may contaminate the environment and require additional filtration systems. This not only increases operational costs but also presents environmental challenges, particularly in applications where oil contamination must be minimized.

Market Alternatives Offering Better Performance: For applications requiring a pumping speed greater than 200 m³/h, there are more suitable alternatives to rotary vane vacuum pumps. Two of the most effective options are the Roots vacuum pump and the screw vacuum pump. Both of these technologies offer advantages that make them more appropriate for high-capacity applications.

Recommended Alternatives: Roots Vacuum Pumps and Screw Vacuum Pumps

Roots Vacuum Pump:

High Capacity: Roots vacuum pumps are specifically designed for high-volume applications. They are capable of achieving very high pumping speeds without the need for excessive mechanical complexity.

Efficiency: Roots pumps operate efficiently at high speeds, with less energy consumption compared to rotary vane pumps at similar capacities.

Temperature Management: With lower internal friction and less heat generation, Roots vacuum pumps are less prone to overheating, making them more reliable for continuous operation at high speeds.

Screw Vacuum Pump:

Oil-Free Operation: Screw vacuum pumps are dry pumps, meaning they do not rely on oil for operation. This eliminates the risks associated with oil contamination and reduces maintenance requirements.

Durability: The robust design of screw pumps allows them to handle high-speed applications with minimal wear and tear, providing longer service life and lower maintenance costs.

Energy Efficiency: Screw vacuum pumps are highly efficient at converting electrical energy into pumping power, making them cost-effective for large-scale operations.

Choosing the Right Pump for High-Speed Applications

While the rotary vane vacuum pump remains a reliable workhorse for many vacuum applications, it is not the most suitable choice when pumping speeds exceed 200 m³/h. The limitations in efficiency, mechanical complexity, and heat management make it less ideal for large-scale operations. Instead, consider the advantages of Roots vacuum pumps or screw vacuum pumps, both of which offer superior performance, lower maintenance requirements, and better overall efficiency in high-capacity applications.

When selecting a vacuum pump, it's essential to match the pump's capabilities with your specific needs. By carefully considering the demands of your application, you can ensure that you choose the right technology for the job—one that offers reliability, efficiency, and cost-effectiveness.

Double Stage Vacuum Pump (VP245) 5CFM

Vacuum pumps are an essential tool in a variety of industries, playing a critical role in applications that require the removal of gases and air from sealed environments. One of the most efficient and widely used types of vacuum pumps is the double-stage vacuum pump, and the VP45 model exemplifies superior performance, reliability, and advanced technology. From HVAC and refrigeration maintenance to laboratory applications, this pump stands out for its high vacuum capabilities. In this article, we’ll dive into the details of the double-stage vacuum pump VP45, its working mechanism, applications, and pricing, particularly in the Indian market.

What is Double Stage Vacuum Pump ?

A double-stage vacuum pump, like the VP45, operates in two phases to achieve higher vacuum levels. Unlike single-stage pumps that only compress air once, a double-stage vacuum pump compresses the air twice, resulting in a deeper vacuum. This deeper vacuum level is essential for processes that demand high precision, such as air conditioning (AC) system maintenance, refrigeration system evacuation, and scientific research applications.

The VP45 model is particularly notable for its advanced design, offering greater vacuum efficiency and reliability for professionals. Its double-stage design makes it capable of reaching low pressure levels (high vacuum), making it suitable for applications that single-stage pumps may not be able to handle.

Key Features of the Double Stage Vacuum Pump VP 245 ?

The VP45 double-stage vacuum pump comes equipped with several features that make it an ideal tool for both professionals and hobbyists in industries such as HVAC, refrigeration, and laboratories. Here are some of the standout features:

Two-Stage Operation: The two-stage mechanism provides a higher level of vacuum precision compared to single-stage pumps, making the VP45 more suitable for demanding applications.

Robust Construction: The VP45 is built from high-quality materials designed to withstand the rigors of daily use. Its heavy-duty construction ensures durability and longevity.

Efficient Cooling System: To prevent overheating, the VP45 is equipped with an efficient cooling system that keeps the pump functioning optimally during extended use.

Low Noise Operation: Unlike many industrial machines, the VP45 operates quietly, allowing for a less disruptive working environment.

Thermal Protection: The pump is equipped with a thermal protection system that prevents it from overheating, ensuring long-lasting performance even in high-demand situations.

Double Stage Vacuum Pump Working ?

Understanding how a double-stage vacuum pump works is essential for grasping its advantages over single-stage models. Here's how it operates:

Stage One: In the first stage of the process, the pump reduces the atmospheric pressure in the system by compressing the air from the vacuum chamber. This stage works similarly to a single-stage vacuum pump and reaches a basic vacuum level by expelling the air through an exhaust port.

Stage Two: The second stage kicks in to further reduce the pressure. This stage compresses the remaining air, removing it completely to create a much deeper vacuum. By performing this second compression, the VP45 can achieve much lower pressure levels, allowing it to reach higher vacuums than single-stage pumps.

Oil Lubrication: The pump uses oil as a lubricant and sealant, which plays a crucial role in reducing wear and tear on the moving parts while maintaining an airtight seal. This ensures smooth, long-lasting performance.

Rotary Vane Mechanism: The VP45 features a rotary vane design where rotating vanes trap air in compartments. As the rotor spins, the vanes push the air towards the exhaust, where it’s expelled. This process repeats continuously, but in two stages, to achieve a more complete vacuum.

Appilcations of Double Stage Vacuum Pumps

Double-stage vacuum pumps like the VP45 have a broad range of applications, thanks to their ability to achieve high levels of vacuum. Here are some of the key industries and tasks that benefit from the use of a double-stage vacuum pump:

1. Air Conditioning (AC) and Refrigeration

In air conditioning (AC) systems, a vacuum pump is used to remove moisture and air from the refrigerant lines before charging the system with refrigerant gas. This process ensures the system runs efficiently and prevents contamination that can damage components over time. The double-stage vacuum pump for AC systems ensures that the system is evacuated to the necessary vacuum depth, eliminating moisture and air.

2. HVAC Systems

For HVAC professionals, the VP45 is an invaluable tool. It ensures that the refrigerant system is properly evacuated, which is critical for the overall health and efficiency of the system. A properly vacuumed system reduces the risk of leaks, corrosion, and inefficient operation.

3. Laboratories

In laboratories, vacuum pumps are used for a variety of tasks, such as vacuum filtration, freeze drying, and creating controlled environments for experiments. The VP45’s ability to achieve deeper vacuums makes it ideal for these applications.

4. Industrial Applications

Many industrial applications, such as food packaging, require a vacuum environment. The VP45 can be used to create a vacuum that preserves food products by removing air, thus extending their shelf life.

5. Medical Equipment

Double-stage vacuum pumps are also used in medical equipment, such as autoclaves, to ensure sterile environments by removing air and steam from medical devices during sterilization processes.

The role of Lubricated Rotary Vane Vacuum Pump in medical applications

High efficient rotary vane vacuum pumps are dependable air-cooled, ideal for small facilities, easy installation and flexible equipment layout.

[wsvacuum]

Why Choose Rotary Vane Vacuum Pump is Not Ideal for Pumping Speed > 200 m³/h

When your application requires a pumping speed greater than 200 m³/h, it's time to reconsider if a rotary vane vacuum pump is the right choice. Although the rotary vane vacuum pump is a widely used and reliable option in many industries, there are several reasons why it may not be the best choice for higher pumping speeds. In this article, we'll explore the limitations of rotary vane vacuum pumps in high-capacity applications and recommend alternative solutions like Roots vacuum pumps and screw vacuum pumps that are better suited for these demands.

The Limitations of Rotary Vane Vacuum Pumps at High Pumping Speeds

Increased Mechanical Complexity and Maintenance Requirements: As the pumping speed increases, the size and complexity of a rotary vane vacuum pump must also increase. Larger vanes and rotors are required to maintain the higher flow rate, resulting in a heavier and more intricate design. This increase in mechanical complexity leads to higher maintenance demands, with more frequent service intervals and the potential for increased wear and tear on components. In turn, this drives up both the operational and maintenance costs.

Efficiency Drops and Higher Energy Consumption: Rotary vane vacuum pumps operate efficiently within a certain range of speeds. However, when the required pumping speed exceeds 200 m³/h, the efficiency of these pumps tends to decrease. To maintain such high speeds, the pump must operate at higher rotational speeds, which results in significantly increased energy consumption. This inefficiency not only raises energy costs but also makes the rotary vane pump less competitive when compared to other pump technologies better suited to high flow rates.

Temperature Control and Heat Dissipation Challenges: The mechanical action within a rotary vane vacuum pump generates heat, and at higher pumping speeds, this heat can become excessive. Managing this heat effectively is critical to ensuring the pump's longevity and reliability. However, at pumping speeds above 200 m³/h, the ability to dissipate heat adequately becomes a challenge. This can lead to overheating, increased wear on internal components, and potentially, pump failure. These risks make the rotary vane vacuum pump a less reliable option for high-speed applications.

Oil Consumption and Contamination Risks: Rotary vane vacuum pumps rely on oil for lubrication and sealing. As the pumping speed increases, so does the consumption of oil. Additionally, the higher operating speeds can lead to greater oil mist generation, which may contaminate the environment and require additional filtration systems. This not only increases operational costs but also presents environmental challenges, particularly in applications where oil contamination must be minimized.

Market Alternatives Offering Better Performance: For applications requiring a pumping speed greater than 200 m³/h, there are more suitable alternatives to rotary vane vacuum pumps. Two of the most effective options are the Roots vacuum pump and the screw vacuum pump. Both of these technologies offer advantages that make them more appropriate for high-capacity applications.

Recommended Alternatives: Roots Vacuum Pumps and Screw Vacuum Pumps

Roots Vacuum Pump:

High Capacity: Roots vacuum pumps are specifically designed for high-volume applications. They are capable of achieving very high pumping speeds without the need for excessive mechanical complexity.

Efficiency: Roots pumps operate efficiently at high speeds, with less energy consumption compared to rotary vane pumps at similar capacities.

Temperature Management: With lower internal friction and less heat generation, Roots vacuum pumps are less prone to overheating, making them more reliable for continuous operation at high speeds.

Screw Vacuum Pump:

Oil-Free Operation: Screw vacuum pumps are dry pumps, meaning they do not rely on oil for operation. This eliminates the risks associated with oil contamination and reduces maintenance requirements.

Durability: The robust design of screw pumps allows them to handle high-speed applications with minimal wear and tear, providing longer service life and lower maintenance costs.

Energy Efficiency: Screw vacuum pumps are highly efficient at converting electrical energy into pumping power, making them cost-effective for large-scale operations.

Choosing the Right Pump for High-Speed Applications

While the rotary vane vacuum pump remains a reliable workhorse for many vacuum applications, it is not the most suitable choice when pumping speeds exceed 200 m³/h. The limitations in efficiency, mechanical complexity, and heat management make it less ideal for large-scale operations. Instead, consider the advantages of Roots vacuum pumps or screw vacuum pumps, both of which offer superior performance, lower maintenance requirements, and better overall efficiency in high-capacity applications.

When selecting a vacuum pump, it's essential to match the pump's capabilities with your specific needs. By carefully considering the demands of your application, you can ensure that you choose the right technology for the job—one that offers reliability, efficiency, and cost-effectiveness.

A rotary vane pump is a clever mechanism that functions similarly to any other sort of air compressor ins most basic form. With an intake valve and an exhaust valve, the pump creates suction in the pump chamber.

[newrockvoipgateway]

The limit pressure of vacuum pump

Shortly after the vacuum pump started to work, the minimum pressure P'g appeared. The vacuum pump continues to operate. Because of the increase of vacuum pump temperature, the saturated vapor pressure and viscosity of vacuum pump oil rise and viscosity drop, and the inlet pressure slightly rises to PG. PG is the stable minimum pressure obtained by the vacuum pump, and also the limit pressure of the vacuum pump. The limit pressure of the rotary vane vacuum pump is related to the type of vacuum gauge used in measurement. When the compression vacuum meter is used, the limit pressure value is about one order of magnitude lower than that measured by the heat conduction vacuum meter (thermocouple or piezometer, etc.). This is because the former can only measure the partial pressure of permanent gas, the latter is the total pressure of the compressed gas. The current regulations of our country use compression vacuum gauge to measure the limit pressure of oil seal mechanical vacuum pump. The circulating oil quantity of vacuum pump also affects the limit pressure of vacuum pump. With the increase of oil quantity, the better sealing effect is, the relationship between the limit pressure and oil quantity of vacuum pump changes, and the saturation vapor pressure Po of oil is achieved. In fact, there is a lot of air and water in the vacuum pump oil. After the vacuum pump oil enters the vacuum pump cavity, the air and water absorbed in the vacuum pump oil are released. The relationship between the limit pressure and the oil quantity of the vacuum pump develops upward. Generally, the vacuum pump oil should be kept on the specified oil level, so that the circulating oil quantity of the vacuum pump should be kept to a certain extent. For double stage vacuum pump, vacuum pump oil can enter high vacuum stage only after degassing at low vacuum stage, so that the amount of air discharge of vacuum pump oil in high vacuum stage can be reduced, so as to reduce the limit pressure of vacuum pump. The limit pressure of vacuum pump is related to the working temperature of vacuum pump oil. The higher the oil temperature, the higher the saturated vapor pressure of the oil, the higher the limit pressure of the vacuum pump.

"Tesla's New Monarch of Machines."

New York Herald, Oct. 15, 1911.

Noted Balkan Scientist Claims to Have Perfected an Engine That Will Develop Ten Horsepower to Every Pound of Weight, and Promises Soon to Give to the World a Flying Machine Without Wings, Propellers or Gas Bag. Characterizes Aeroplanes of Today as Mere Dangerous Toys Compared With the Safe and Stable Appliance Which Will Be Used in a Short Time to Dash Through the Air at a Speed Now Unimagined

Just what is your new invention?" I asked.

"I have accomplished what mechanical engineers have been dreaming about ever since the invention of steam power," replied Dr. Tesla. "That is the perfect rotary engine. It happens that I have also produced an engine which will give at least twenty-five times as much power to a pound of weight as the lightest weight engine of any kind that has yet been produced.

"In doing this I have made use of two properties which have always been known to be possessed by all fluids, but which have not heretofore been utilized. These properties are adhesion and viscosity.

"Put a drop of water on a metal plate. The drop will roll off, but a certain amount of the water will remain on the plate until it evaporates or is removed by some absorptive means. The metal does not absorb any of the water, but the water adheres to it.

"The drop of water may change its shape, but until its particles are separated by some external power it remains intact. This tendency of all fluids to resist molecular separation is viscosity. It is especially noticeable in the heavier oils.

"It is these properties of adhesion and viscosity that cause the "skin friction" that impedes a ship in its progress through the water or an aeroplane in going through the air. All fluids have these qualities--and you must keep in mind that air is a fluid, all gases are fluids, steam is fluid. Every known means of transmitting or developing mechanical power is through a fluid medium.

"Now, suppose we make this metal plate that I have spoken of circular in shape and mount it at its centre on a shaft so that it can be revolved. Apply power to rotate the shaft and what happens? Why, whatever fluid the disk happens to be revolving in is agitated and dragged along in the direction of rotation, because the fluid tends to adhere to the disk and the viscosity causes the motion given to the adhering particles of the fluid to be transmitted to the whole mass.  Here, I can show you better than tell you."

Dr. Tesla led the way into an adjoining room.  On a desk was a small electric motor and mounted on the shaft were half a dozen flat disks, separated by perhaps a sixteenth of an inch from one another, each disk being less than that in thickness. He turned a switch and the motor began to buzz. A wave of cool air was immediately felt.

"There we have a disk, or rather a series of disks, revolving in a fluid--the air,-- said the inventor. "You need no proof to tell you that the air is being agitated and propelled violently. If you will hold your hand over the centre of these disks--you see the centres have been cut away--you will feel the suction as air is drawn in to be expelled from the peripheries of the disks.

"Now, suppose these revolving disks were enclosed in an air tight case, so constructed that the air could enter only at one point and be expelled only at another--what would we have?"

"You'd have an air pump," I suggested.

"Exactly--an air pump or blower," said Dr. Tesla.

"There is one now in operation delivering ten thousand cubic feet of air a minute. "Now, come over here."

He stepped across the hall and into another room, where three or four draughtsmen were at work and various mechanical and electrical contrivances were scattered about. At one side of the room was what appeared to be a zinc or aluminum tank, divided into two sections, one above the other, while a pipe that ran along the wall above the upper division of the tank was connected with a little aluminum case about the size and shape of a small alarm clock. A tiny electric motor was attached to a shaft that protruded from one side of the aluminum case. The lower division of the tank was filled with water.

"Inside of this aluminum case are several disks mounted on a shaft and immersed in a fluid, water," said Dr. Tesla. "From this lower tank the water has free access to the case enclosing the disks. This pipe leads from the periphery of the case. I turn the current on, the motor turns the disks and as I open this valve in the pipe the water flows."

He turned the valve and the water certainly did flow. Instantly a stream that would have filled a barrel in a very few minutes began to run out of the pipe into the upper part of the tank and thence into the lower tank.

"This is only a toy," said Dr. Tesla. "There are only half a dozen disks" --runners,-- I call them--each less than three inches in diameter, inside of that case. They are just like the disks you saw on the first motor--no vanes, blades or attachments of any kind.  Just perfectly smooth, flat disks revolving in their own planes and pumping water because of the viscosity and adhesion of the fluid. One such pump now in operation, with eight disks, eighteen inches in diameter, pumps four thousand gallons a minute to a height of 360 feet."

We went back into the big, well lighted office. I was beginning to grasp the new Tesla principle.

"Suppose now we reversed the operation," continued the inventor. "You have seen the disks acting as a pump. Suppose we had water, or air under pressure, or steam under pressure, or gas under pressure, and let it run into the case in which the disks are contained--what would happen?"

"The disks would revolve and any machinery attached to the shaft would be operated--you would convert the pump into an engine," I suggested.

"That is exactly what would happen--what does happen," replied Dr. Tesla. "It is an engine that does all that engineers have ever dreamed of an engine doing, and more. Down at the Waterside power station of the New York Edison Company, through their courtesy, I have had a number of such engines in operation.  In one of them the disks are only nine inches in diameter and the whole working part is two inches thick.  With steam as the propulsive fluid it develops 110-horse power, and could do twice as much."

"You have got what Professor Langley was trying to evolve for his flying machine--an engine that will give a horse power for a pound of weight," I suggested.

Ten Horse Power to the Pound.

"I have got more than that," replied Dr. Tesla.  "I have an engine that will give ten horse power to the pound of weight. That is twenty-five times as powerful as the lightest weight engine in use today. The lightest gas engine used on aeroplanes weighs two and one-half pounds to the horse power. With two and one-half pounds of weight I can develop twenty-five horse power."

"That means the solution of the problem of flying," I suggested.

"Yes, and many more," was the reply. "The applications of this principle, both for imparting power to fluids, as in pumps, and for deriving power from fluids, as in turbine, are boundless. It costs almost nothing to make, there is nothing about it to get out of order, it is reversible--simply have two ports for the gas or steam, to enter by, one on each side, and let it into one side or other. There are no blades or vanes to get out of order--the steam turbine is a delicate thing."

I remembered the bushels of broken blades that were gathered out of the turbine casings of the first turbine equipped steamship to cross the ocean, and realized the importance of this phase of the new engine.

"Then, too," Dr. Tesla went on, "there are no delicate adjustments to be made. The distance between the disks is not a matter of microscopic accuracy and there is no necessity for minute clearances between the disks and the case. All one needs is some disks mounted on a shaft, spaced a little distance apart and cased so that a fluid can enter at one point and go out at another. If the fluid enters at the centre and goes out at the periphery it is a pump. If it enters at the periphery and goes out at the center it is a motor.

"Coupling these engines in series, one can do away with gearing in machinery. Factories can be equipped without shafting. The motor is especially adapted to automobiles, for it will run on gas explosions as well as on steam. The gas or steam can be let into a dozen ports all around the rim of the case if desired. It is possible to run it as a gas engine with a continuous flow of gas, gasoline and air being mixed and the continuous combustion causing expansion and pressure to operate the motor. The expansive power of steam, as well as its propulsive power, can be utilized as in a turbine or a reciprocating engine. By permitting the propelling fluid to move along the lines of least resistance a considerably larger proportion of the available power is utilized.

"As an air compressor it is highly efficient. There is a large engine of this type now in practical operation as an air compressor and giving remarkable service. Refrigeration on a scale hitherto never attempted will be practical, through the use of this engine in compressing air, and the manufacture of liquid air commercially is now entirely feasible.

"With a thousand horse power engine, weighing only one hundred pounds, imagine the possibilities in automobiles, locomotives and steamships. In the space now occupied by the engines of the Lusitania twenty-five times her 80,000 horse power could be developed, were it possible to provide boiler capacity sufficient to furnish the necessary steam."

"And it makes the aeroplane practical," I suggested.

"Not the aeroplane, the flying machine," responded Dr. Tesla. "Now you have struck the point in which I am most deeply interested--the object toward which I have been devoting my energies for more than twenty years--the dream of my life. It was in seeking the means of making the perfect flying machine that I developed this engine.

"Twenty years ago I believed that I would be the first man to fly; that I was on the track of accomplishing what no one else was anywhere near reaching. I was working entirely in electricity then and did not realize that the gasoline engine was approaching a perfection that was going to make the aeroplane feasible. There is nothing new about the aeroplane but its engine, you know.

"What I was working on twenty years ago was the wireless transmission of electric power. My idea was a flying machine propelled by an electric motor, with power supplied from stations on the earth. I have not accomplished this as yet, but am confident that I will in time.

"When I found that I had been anticipated as to the flying machine, by men working in a different field, I began to study the problem from other angles, to regard it as a mechanical rather than an electrical problem. I felt certain there must be some means of obtaining power that was better than any now in use. And by vigorous use of my gray matter for a number of years, I grasped the possibilities of the principle of the viscosity and adhesion of fluids and conceived the mechanism of my engine. Now that I have it, my next step will be the perfect flying machine."

"An aeroplane driven by your engine?" I asked.

"Not at all," said Dr. Tesla. "The aeroplane is fatally defective. It is merely a toy--a sporting play-thing. It can never become commercially practical. It has fatal defects. One is the fact that when it encounters a downward current of air it is helpless. The "hole in the air" of which aviators speak is simply a downward current, and unless the aeroplane is high enough above the earth to move laterally but can do nothing but fall.

"There is no way of detecting these downward currents, no way of avoiding them, and therefore the aeroplane must always be subject to chance and its operator to the risk of fatal accident. Sportsmen will always take these chances, but as a business proposition the risk is too great.

"The flying machine of the future--my flying machine--will be heavier than air, but it will not be an aeroplane. It will have no wings. It will be substantial, solid, stable. You cannot have a stable airplane. The gyroscope can never be successfully applied to the airplane, for it would give a stability that would result in the machine being torn to pieces by the wind, just as the unprotected aeroplane on the ground is torn to pieces by a high wind.

"My flying machine will have neither wings nor propellers. You might see it on the ground and you would never guess that it was a flying machine. Yet it will be able to move at will through the air in any direction with perfect safety, higher speeds than have yet been reached, regardless of weather and oblivious of "holes in the air" or downward currents. It will ascend in such currents if desired. It can remain absolutely stationary in the air, even in a wind, for great length of time. Its lifting power will not depend upon any such delicate devices as the bird has to employ, but upon positive mechanical action."

"You will get stability through gyroscopes?" I asked.

"Through gyroscopic action of my engine, assisted by some devices I am not yet prepared to talk about," he replied.

"Powerful air currents that may be deflected at will, if produced by engines and compressors sufficiently light and powerful, might lift a heavy body off the ground and propel it through the air," I ventured, wondering if I had grasped the inventor's secret.

Dr. Tesla smiled an inscrutable smile.

"All I have to say on that point is that my airship will have neither gas bag, wings nor propellers," he said. "It is the child of my dreams, the product of years of intense and painful toil and research. I am not going to talk about it any further. But whatever my airship may be, here at least is an engine that will do things that no other engine ever has done, and that is something tangible."
