In November we'll be in Galveston, TX, conducting a research flight series to examine technology to be used in future community response testing with the agency’s Low-Boom Flight Demonstrator aircraft. • The flight series, called Quiet Supersonic Flights 2018, or QSF18, will use a NASA F/A-18 research aircraft performing a unique supersonic dive maneuver that produces a sound similar to a soft “thump” in comparison to the sonic boom typically associated with supersonic flight. The goal of the flights is to study techniques for obtaining accurate community response data, using surveys, to the reduced sounds of supersonic flight over a community that is relatively unfamiliar with these sounds. • #nationalaviationday #aviationday #nasa #aviation #aeronautics #flight #supersonic #xplane #x59 #research #technology

In 2017 we finished testing a new cockpit-based air traffic management tool, Flight Deck Interval Management, designed to automatically provide pilots with more precise spacing information on approach into a busy airport. • The technology is intended to help airplanes spend less time in the air, save money on fuel, and reduce engine emissions – all while improving schedule efficiency to help passengers arrive on time. • Using a Boeing 757 and Dassault Falcon business jet provided by Honeywell, and a Boeing 737 provided by United Airlines, the aircraft flew together above Washington state during 18 days of tests spread over a month. Early analysis indicates the tool worked as expected. Additional data review will take some time, but for now the research team involving @nasa_langley and @nasaames, along with Boeing, Honeywell and United, are celebrating the successful flight test campaign. • #nationalaviationday #aviationday #nasa #aviaton #aeronautics #flight #nasalangley #nasaames #research #technology

Have you heard? We recently awarded @lockheedmartin a contract to build a faster-than-sound X-plane — the X-59 QueSST— that will demonstrate quiet supersonic technologies over land. • Part of the Low-boom Flight Demonstration mission, the X-59 is shaped so that supersonic shockwaves do not coalesce together to create the characteristic sonic booms, which prompted the government to ban supersonic flight over land years ago. • Once built, and its quiet supersonic technologies confirmed, the X-59 will fly over several U.S. towns or cities – yet to be selected – and gather data from residents on the ground about their perception of the sound the supersonic aircraft generates. • #nationalaviationday #aviationday #nasa #aviation #aeronautics #flight #x59 #xplane #supersonic #research #technology

There is a new era dawning in air transportation: Urban Air Mobility. @nasaaero is working on a safe and efficient air transportation system where everything from small package delivery drones to passenger-carrying air taxis operate over populated areas, from small towns to the largest cities. • "The convergence of technologies, and new business models enabled by the digital revolution, is making it possible to explore this new way for people and cargo to move within our cities,” says Dr. Jaiwon Shin, NASA’s associate administrator for aeronautics research. • But there’s still much research to be done, tests performed, demonstrations conducted, and operating rules and regulations to be written and adopted before you should expect same-day package delivery by air on the roof of your office building downtown. • #nationalaviationday #aviationday #nasa #aviation #aeronautics #flight #drones #unmanned #research #technology

At @nasaglenn we're exploring a relatively new phenomenon called ice crystal icing: when ice crystals found at high altitudes enter an engine’s core, causing loss of thrust, engine stall, surge and potential damage. • The icing research being done at NASA Glenn is one-of-a-kind, and NASA currently has the only facility in the world that can test full-sized engines and rigs at relevant ice crystal icing conditions. • As more planes enter the airspace and the likelihood of flying into icing regions increases, Glenn’s icing research is of the utmost importance to the future of engine design and aviation safety. • #nationalaviationday #aviationday #nasa #aviation #aeronautics #flight #research #technology

The Icing Research Tunnel (IRT) @nasaglenn is the longest running, second largest icing facility in the world and has been in operation since 1944. Most ice protection technologies in use today were largely developed at this facility. In this facility, natural icing conditions are duplicated to test the effects of in-flight icing conditions on actual aircraft components such as wings tails and engine inlets. • A variety of tests are performed in the IRT including fundamental studies of icing physics, icing prediction validation, and ice protection system development and certification. These tests have been used successfully to reduce flight test hours for ice detection instrumentation and ice protection systems certification. • #nationalaviationday #aviationday #nasa #nasaglenn #aviation #aeronautics #flight #research #technology

Our icing research involves the development of methods for evaluating the growth of ice on aircraft surfaces or engines, and the effects ice may have on the behavior of aircraft in flight. • At @nasaglenn, they “We Freeze to Please." Their icing research teams utilize a refrigerated wind tunnel, an engine test cell, and small scale laboratories to create icing conditions for models and airfoils on the ground, as well as flying laboratories to study aircraft icing in the sky. They have also developed software tools to help predict ice growth and the effects of ice contamination on aircraft or inside of engines. • The icing research conducted at NASA leads to developed and validated simulation methods, both computational and experimental, suitable for use as both certification and design tools when evaluating aircraft systems for operation in icing conditions. We are challenged to look forward to new technologies being developed and consider what potential issues may arise related to flight into icing. • #nationalaviationday #aviationday #nasa #nasaglenn #aviation #aeronautics #flight #icing #windtunnel #research #technology
