Nasa transonic wind tunnel
Witryna2 kwi 2024 · The largest low-speed wind tunnel is the national full-size facility (NFSF) at NASA's Ames Center. The large transonic wind tunnel with the highest Reynolds number is the national transonic facility (NTF) of Langley Center in the United States. It is a low-temperature wind tunnel with a section size of 2.5 m × 2.5 m in the test section. WitrynaIn wind tunnel tests, the low-frequency and large-amplitude vibration of the cantilever sting result in poor test data in pitch plane and yaw plane, more seriously, even threatens the safety of wind tunnel tests. To ensure the test data quality, a multidimensional vibration suppression method is proposed to withstand the vibration from any …

Witryna8 lis 2024 · NASA and Boeing are collaborating to develop a Transonic Truss-Braced Wing (TTBW) aircraft concept design, which contains advancements in technology with the potential to improve fuel efficiency for commercial aircraft. Witryna9 cze 2016 · Transonic Dynamics Tunnel Overview The TDT is a unique wind tunnel facility that is optimized for aeroelastic, dynamic, or high-risk testing. A unique feature is the ability to use either Air or R-134a heavy gas as a test medium. R-134a has a higher density, lower viscosity, and lower speed of sound than air.
WitrynaNewer wind tunnels were designed, so researchers could test newer wing designs without risking test pilots' lives. The slotted-wall transonic tunnel was designed by NASA and allowed researchers to test wings and different airfoils in transonic airflow to find the best wingtip shape for sonic speeds.
