Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist.
Jan 5, 2024 · NASA made aviation history with the first and second successful flights of a scramjet-powered airplane at hypersonic speeds – speeds greater than Mach 5 or five times the speed of sound.
Most often propeller-driven and commercial turbofan aircraft with high-aspect-ratio (slender) wings, and rounded features like the nose and leading edges. The subsonic speed range is that range of speeds within which, all of the airflow over an aircraft is less than Mach 1.
Jun 28, 2018 · The famed SR-71 Blackbird reconnaissance aircraft used such a system in the 1960s, as have multiple missiles and experimental aircraft. Boeing is collaborating with Northrop Grumman Innovation...
Jan 25, 2023 · Quarterhorse, the Air Force's next hypersonic aircraft, has taken an epic leap. The SR-71 Blackbird successor is a step closer to breaking the airspeed record.
Mar 12, 2024 · Stratolaunch, a company that aims to launch hypersonic vehicles from the world's largest airplane, achieved high supersonic speed over the Pacific Ocean on March 9, 2024. The test flight was the first powered flight of the Talon-A1 vehicle, which is designed to serve as a private hypersonic testbed.
Jun 21, 2024 · Vehicles that travel at hypersonic speeds fly faster than five times the speed of sound. NASA studies the fundamental science of hypersonics to understand it better and applies this understanding to enable point-to-point and space access hypersonic vehicles.
