Aeronautics
Langley Research Center performs critical research on aeronautics, including wake vortex behavior, fixed-wing aircraft, rotary wing aircraft, air safety, human factors and aerospace engineering. LaRC supported the design and testing of the hypersonic X-43, which achieved a world speed record of Mach 9.6 (almost 7,000 miles per hour). LaRC assisted the NTSB in the investigation of the crash of American Airlines Flight 587.
Work began in July 2011 to remove the 1940s era 16 feet (4.9 m) transonic wind tunnel. The facility supported development and propulsion integration research for many military aircraft including all fighters since 1960 (F-14, F-15, F-16, F-18 and the Joint Strike Fighter) but had been inactive since 2004. Langley retained transonic wind tunnel testing capabilities facilities in the National Transonic Facility, a high pressure, cryogenically cooled 8.2 feet (2.5 m) closed loop wind tunnel.
