NASA’s Quesst mission has postponed the inaugural flight of its X-59 quiet supersonic aircraft to 2024. The X-59, an extraordinary experimental aircraft, has posed intricate engineering challenges for NASA researchers collaborating with the primary contractor, Lockheed Martin Skunk Works. Apart from its unique design, the X-59 incorporates innovative technology and components from various established aircraft, including its landing gear from an F-16 and its life-support system adapted from an F-15.

Additional time is required to integrate systems into the aircraft

Given the complexities involved in developing this exceptional aircraft, the Quesst team is diligently addressing several technical issues identified during the course of 2023, when the X-59 was initially slated for its maiden flight. Additional time is required to seamlessly integrate systems into the aircraft and ensure their proper functioning. The team is also resolving intermittent problems with some of the safety-redundant computers that oversee the aircraft’s systems.

Over the past year, Quesst has made consistent progress towards flight readiness. The team completed the finishing touches on the X-59’s tail structure, allowing them to finalize its electrical wiring and advance to critical ground tests. They also moved the aircraft from its assembly facility to the flight line for structural testing.

The X-59’s primary objective is to demonstrate the capability to achieve supersonic flight, exceeding the speed of sound, while minimizing the typical disruptive sonic boom to a subdued sonic thump. NASA intends to conduct flights over several communities to collect data on how people perceive the noise it generates. This data will be provided to U.S. and international regulators to potentially revise regulations that currently prohibit commercial supersonic flight over land.

NASA postpones X-59 flight tests to 2024

Fernando Valduga By Fernando Valduga 10/20/2023 - 10:01am in Technology

NASA postponed the first flight of the X-59 low-noise supersonic demonstrator to 2024, after a series of subsystem problems found during verification tests at Lockheed Martin's Skunk Works facility in Palmdale, California, later this summer, proved more difficult to solve than expected.

"We want to fly as early as possible, but we want to fly safely," says the agency, which - together with Lockheed Martin - has solved a variety of problems of abandonment and redundancy of security systems in various subsystems.

First reported in August, the problems are related to the flight control computer and the hydraulic system and were found during structural coupling tests in Palmdale. The coupling tests were designed to evaluate the interaction between the fuselage and the flight control system, and to ensure the absence of any aeroelastic and aeroservoelastic instabilities.

Developed by Lockheed for NASA's Quiet Supersonic Technology (QueSST) program, the X-59 almost 30 meters long was originally supposed to fly in 2021. However, the latest system-related delays add to a series of delays that included workforce hiring issues, the pandemic and technical challenges related to cabling and the integration of final systems. Until recently, the agency still expected to make the first flight of the X-59 by the end of the year, with a transition soon after to NASA's neighboring Armstrong Flight Research Center at Edwards Air Base for subsequent expansion of the envelope.

Commenting on the delay, NASA states: “This unique experimental aircraft requires unique and complex engineering, and its team encountered several technical challenges last year. The X-59 is currently in the process of integrated testing, which must be completed to help ensure safe and successful flights. NASA plans to release a more specific schedule for the first flight when the flight readiness review is completed, after integrated tests."

The X-59 is designed to collect community response data on the public acceptability of reduced sonic rons. The data will be used by U.S. and international authorities to determine whether a growth standard can be established that allows the release of the current ban on civilian supersonic flights over land, which has been in force since the 1970s.

However, to achieve low-intensity sonic sonic roning at the projected speed of the X-59 of Mach 1.4, the aircraft is configured with a well-sloping hang glider and swinging extended nose section that represents more than one third of the length of the vehicle. Specifically designed with rigidity for high-speed testing, rather than resistance for payload capacity, the long and slender format therefore presents significant aeroelastic challenges.

NASA’s X-59 quiet supersonic research aircraft sits on the apron outside Lockheed Martin’s Skunk Works facility at dawn in Palmdale, California. The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to address one of the primary challenges to supersonic flight over land by making sonic booms quieter.Lockheed Martin Skunk Works NASA and Lockheed Martin formally debuted the agency’s X-59 quiet supersonic aircraft Friday. Using this one-of-a-kind experimental airplane, NASA aims to gather data that could revolutionize air travel, paving the way for a new generation of commercial aircraft that can travel faster than the speed of sound. “This is a major accomplishment made possible only through the hard work and ingenuity from NASA and the entire X-59 team,” said NASA Deputy Administrator Pam Melroy. “In just a few short years we’ve gone from an ambitious concept to reality. NASA’s X-59 will help change the way we travel, bringing us closer together in much less time.” Melroy and other senior officials revealed the aircraft during a ceremony hosted by prime contractor Lockheed Martin Skunk Works at its Palmdale, California facility. The X-59 is at the center of NASA’s Quesst mission, which focuses on providing data to help regulators reconsider rules that prohibit commercial supersonic flight over land. For 50 years, the U.S. and other nations have prohibited such flights because of the disturbance caused by loud, startling sonic booms on the communities below. The X-59 is expected to fly at 1.4 times the speed of sound, or 925 mph. Its design, shaping and technologies will allow the aircraft to achieve these speeds while generating a quieter sonic thump. “It’s thrilling to consider the level of ambition behind Quesst and its potential benefits,” said Bob Pearce, associate administrator for aeronautics research at NASA Headquarters in Washington. “NASA will share the data and technology we generate from this one-of-a-kind mission with regulators and with industry. By demonstrating the possibility of quiet commercial supersonic travel over land, we seek to open new commercial markets for U.S. companies and benefit travelers around the world.” With rollout complete, the Quesst team will shift to its next steps in preparation for first flight: integrated systems testing, engine runs, and taxi testing for the X-59. The aircraft is set to take off for the first time later this year, followed by its first quiet supersonic flight. The Quesst team will conduct several of the aircraft’s flight tests at Skunk Works before transferring it to NASA’s Armstrong Flight Research Center in Edwards, California, which will serve as its base of operations. “Across both teams, talented, dedicated, and passionate scientists, engineers, and production artisans have collaborated to develop and produce this aircraft,” said John Clark, vice president and general manager at Lockheed Martin Skunk Works. “We’re honored to be a part of this journey to shape the future of supersonic travel over land alongside NASA and our suppliers.” Once NASA completes flight tests, the agency will fly the aircraft over several to-be-selected cities across the U.S., collecting input about the sound the X-59 generates and how people perceive it. NASA will provide that data to the Federal Aviation Administration and international regulators. The X-59 is a unique experimental airplane, not a prototype – its technologies are meant to inform future generations of quiet supersonic aircraft. At 99.7 feet long and 29.5 feet wide, the aircraft’s shape and the technological advancements it houses will make quiet supersonic flight possible. The X-59’s thin, tapered nose accounts for almost a third of its length and will break up the shock waves that would ordinarily result in a supersonic aircraft causing a sonic boom. Due to this configuration, the cockpit is located almost halfway down the length of the aircraft – and does not have a forward-facing window. Instead, the Quesst team developed the eXternal Vision System, a series of high-resolution cameras feeding a 4K monitor in the cockpit. The Quesst team also designed the aircraft with its engine mounted on top and gave it a smooth underside to help keep shockwaves from merging behind the aircraft and causing a sonic boom.

Breaking the Sound Barrier Without the Boom

NASA, in collaboration with Lockheed Martin, is set to redefine air travel with the upcoming launch of the X-59, an experimental supersonic aircraft designed to eliminate the disruptive sonic boom. This innovative jet, expected to take flight in 2025, is engineered to exceed speeds of 900 mph, surpassing the sound barrier of 761 mph. Unlike conventional supersonic aircraft, which generate a deafening boom when breaking the sound barrier, the NASA X-59 will produce a softer “thump,” similar to the sound of a closing car door.

Extensive testing is underway to ensure the aircraft’s noise-reduction technology functions as intended. A recent test in California demonstrated the aircraft’s capabilities, with images showing flames erupting from its engine. These tests confirm the X-59’s potential to travel at high speeds while maintaining significantly reduced noise levels. NASA remains focused on refining this technology to make supersonic travel a feasible and quiet reality.

Paving the Way for Supersonic Commercial Flights

The success of the NASA X-59 could lead to the removal of long-standing restrictions on supersonic travel over the United States. Currently, a federal ban prevents commercial aircraft from flying at supersonic speeds over land due to the disruptive sonic booms. If the X-59 proves successful in mitigating noise pollution, it could pave the way for regulatory changes that allow faster air travel across the country.

NASA intends to conduct multiple test flights to analyze the aircraft’s impact on communities below its flight path. By collecting data on noise perception and aircraft performance, the agency aims to demonstrate that supersonic travel can be both efficient and unobtrusive. The findings will help determine whether the U.S. government will lift the ban, potentially revolutionizing commercial aviation.

Beyond enhancing air travel for passengers, the X-59’s technology holds promise for emergency medical services and military operations, where rapid transportation can be crucial. NASA’s ongoing research highlights its commitment to advancing aviation while addressing environmental and societal concerns.

The Race for Supersonic Dominance

While NASA and Lockheed Martin push forward with the X-59, private industry is also making strides in supersonic aviation. Boom Supersonic, a Colorado-based company, recently achieved a milestone with its XB-1 jet. On January 28, the company successfully conducted its first flight, marking a significant step toward commercial supersonic travel. With 12 flights completed, the XB-1 has already broken the sound barrier over California, earning the title of the world’s fastest airliner.

Despite competition, the X-59 remains a pioneering project in NASA’s pursuit of quiet supersonic technology. The jet’s first public flight is scheduled for later this year, with plans to conduct trials over populated areas to assess its noise impact. If successful, the NASA X-59 could reshape the future of air travel, making supersonic speeds more accessible and practical for commercial use. The world now eagerly awaits the results of NASA’s ambitious test flights, which could mark the beginning of a new era in aviation.

NASA’s X-59 Quiet SuperSonic Technology X-plane, or QueSST. Image credits: Lockheed Martin

This radiometric system measures the temperature of any components of heat shields, aeroshells, hot gas flow paths, or proximate structures. There are likely opportunities for ARMS to benefit many civilian and consumer efforts not currently considered.

The NASA Technology Transfer Office would like to identify and license to one or more organizations or teams that can mature this technology, with the long-term goal of commercializing these sensors.

Radiometric temperature measurement: Overview

NASA efforts to support commercial Low Earth Orbit (LEO) have led to many new technologies, such as ARMS. The challenge of measuring high temperatures with a low SWaP system is present across a variety of air and space vehicles, as well as ground test and defense applications.

Although commercial LEO, supersonic, and hypersonic development are obvious areas with the need for high temperature data, other possible applications exist for this wireless and contactless high-temperature measurement technology.

Radiometric system ARMS utilizes wireless fiber optic communication with a Data Acquisition Unit (DAU) separate from the measured heat source. The tested temperature range for the sensor is 600⁰C to 2900⁰C (1112⁰F to 5252⁰F). The advantages of ARMS over thermocouples and other technologies in use include:

A contactless system that eliminates consumables that burn away during conventional high temperature measurement

A temperature range which far exceeds the capacities of thermocouples

Better quality and quantity of data for this higher temperature range due to the fiber optic system, with more accurate and frequent data sampling

NASA hopes to identify and work with the widest practical and appropriate audience of new innovators and to promote awareness of this technology. The ARMS team will supply the winning solution(s) with a non-exclusive license, two (2) prototype systems, and consulting time from the NASA engineering team that will be negotiated during the licensing agreement.

Submissions to this Challenge must be received by Dec 1, 2023.

Revolutionizing Air Travel: NASA's Ambitious Project to Cut New York to London Flight Time to 1.5 Hours

In a bid to redefine the future of air travel, NASA is delving into the realm of supersonic technology with a groundbreaking project that aims to drastically reduce the flight time between New York and London to a mere 1.5 hours. This ambitious endeavor falls under NASA's Commercial Supersonic Technology Project, signaling a new era of rapid and efficient global transportation. In contrast to the current passenger planes cruising at an average speed of 600 mph, NASA is setting its sights on revolutionizing commercial aviation with a supersonic jet capable of traversing the skies at speeds ranging from Mach 2 to Mach 4, equivalent to an astounding 1,535 to 3,045 mph. However, the journey to achieve this supersonic feat is not without its challenges. Present flight regulations across the United States and various nations prohibit supersonic jets from flying over land due to concerns over sonic booms causing noise pollution. Determined to overcome this hurdle, NASA has outlined two pivotal objectives to pave the way for supersonic flights over land. At the heart of these efforts is the Quesst mission, an initiative through which NASA is crafting the X-59 quiet supersonic aircraft. Distinguished by its innovative technology designed to mitigate the deafening roar of a sonic boom into a gentle, ground-level thump, the X-59 is poised to reshape the sonic landscape of supersonic flight. NASA's plan involves flying the X-59 over U.S. skies, meticulously analyzing the impact of its softened sonic boom on the populace. The objective is clear: to amass empirical data that will substantiate the case for revising the regulations barring overland supersonic flights. Drawing inspiration from the advancements achieved through the X-59 program, the commercial supersonic jet will emerge as the culmination of NASA's groundbreaking work. Lori Ozoroski, the esteemed project manager for NASA's Commercial Supersonic Technology Project, remarked, "A decade ago, we embarked on similar concept studies at Mach 1.6-1.8, and the insights gleaned from those studies have guided NASA's research trajectory ever since, including the pivotal strides toward the X-59." As the project accelerates, NASA is poised to award two 12-month contracts to select companies, tasking them with crafting comprehensive concept designs and technology roadmaps. These roadmaps will not only chart the uncharted territory of high-speed air travel but will also delineate potential risks, challenges, and essential technologies necessary to translate the vision of Mach 2-plus travel into an operational reality.

NASA Targets 2024 for First Flight of X-59 Experimental Aircraft

NASA’s Quesst mission has adjusted the scheduled first flight of its X-59 quiet supersonic aircraft to 2024. A one-of-a-kind experimental aircraft, the X-59 has required complex engineering from NASA researchers working with prime contractor Lockheed Martin Skunk Works. In addition to the aircraft’s design, the X-59 also combines new technology with systems and components from […] from NASA https://ift.tt/o0Sj5dk

Laying the Groundwork for a New Generation of Commercial Supersonic Aircraft

Cabin crew, prepare for takeoff. Engines roar; speed increases. You sip a cold beverage as the aircraft accelerates quietly past Mach 1 or around 600 mph. There’s no indication you’re flying over land faster than the speed of sound except when you glance at your watch upon arrival and see you’ve reached your destination in half the time. You leisurely walk off the plane with ample time to explore, finish a final report or visit a familiar face. This reality is closer than you think.

We’re on a mission to help you get to where you want to go in half the time. Using our single-pilot X-59 Quiet SuperSonic Technology (QueSST) research aircraft, we will provide rule-makers the data needed to lift current bans on faster-than-sound air travel over land and help enable a new generation of commercial supersonic aircraft.

The X-59 QueSST is unique in shape. Each element of the aircraft’s design will help reduce a loud sonic boom, typically produced by conventional supersonic aircraft, to a gentle sonic thump, making it quieter for people on the ground. To prove the quiet technology works, we will fly the X-59 over select U.S. communities to gauge the public’s response to the sound.

We are working with Lockheed Martin in Palmdale, California, to manufacture the X-59 and are making significant progress, despite the pandemic.

We finished the majority of work on the wing and closed its interior, marking the halfway point on construction of the aircraft. 

The X-59 team at Lockheed Martin completed the final touches by fastening skins to the wing. A special sealant is applied so that fuel can be carried in the wings of the aircraft.

Moving at a steady pace, technicians continue to work on many parts of the aircraft simultaneously. The forebody section of the aircraft will carry the pilot and all the avionics needed to fly the aircraft.

Because of the X-59’s long nose, the pilot will rely on an eXternal Vision System (XVS), rather than a window, for forward-facing visibility. The XVS will display fused images from an advanced computing system and cameras mounted on the upper and lower part of the aircraft’s nose.

The aft part of the aircraft will hold an F414 GE engine and other critical systems. Unlike typical aircraft, the engine inlet will be located on the upper surface of the X-59 and is one of many features that will help reduce the noise heard on the ground.

Over the next several months, the team will merge all three sections together. After final assembly in 2021, the X-59 will undergo numerous tests to ensure structural integrity of the aircraft and that ¬its components work properly. First flight of the aircraft will be in 2022 and community testing will start in 2024, making way for a new market of quiet commercial supersonic aircraft.
