The first aircraft to fly supersonic in level flight was the American Bell X-1 experimental plane which was powered by a 6,000-pound (2,700 kg) thrust rocket powered by liquid oxygen and ethyl alcohol. Most supersonic aircraft have been military or experimental aircraft. Aviation research during World War II led to the creation of the first ...
The SAI Quiet Supersonic Transport is a 12-passenger design from Lockheed Martin that is to cruise at Mach 1.6, and is to create a sonic boom only 1% as strong as that generated by Concorde. [ 50] The supersonic Tupolev Tu-444 or Gulfstream X-54 have also been proposed.
NASA and Lockheed Martin have finally taken the wraps off of the X-59, a “quiet supersonic” aircraft that may shape the future of both military and civilian air travel.. The X-59 has been ...
NASA’s X-59 Quesst supersonic commercial jet, which is being developed by Lockheed Martin, will have its flight test livestreamed as a demonstration of how quiet it can be in the air. The $247.5 ...

On Wednesday, the company announced plans to build a manufacturing facility at Piedmont Triad International Airport in North Carolina. Once complete, "The Overture Superfactory" will employ ...
Sodar, an acronym of sonic detection and ranging, is a meteorological instrument used as a wind profiler based on the scattering of sound waves by atmospheric turbulence. Sodar equipment is used to measure wind speed at various heights above the ground, and the thermodynamic structure of the lower layer of the atmosphere .
Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. [1] The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.
