transonic regime
1Subsonic and transonic wind tunnel — ubsonic tunnelLow speed wind tunnels are used for operations at very low mach number, with speeds in the test section up to 400 km/h ( 100 m/s, M = 0.3). They are of open return type ( losses. Open wind tunnelThe working principle is based on the …
2High-hypersonic speed regime — Re Entry Speed Regime = Generally, NASA defines high hypersonic as any mach number from 10 to 25 and Re entry speeds as anything greater. Aicraft operating in this regime are the Space Shuttle and various space planes in future development.… …

4military aircraft — Introduction any type of aircraft that has been adapted for military use. Aircraft have been a fundamental part of military power since the mid 20th century. Generally speaking, all military aircraft fall into one of the following… …
5Compressible flow — is the area of fluid mechanics that deals with fluids in which the fluid density varies significantly in response to a change in pressure. Compressibility effects are typically considered significant if the Mach number (the ratio of the flow… …
6Anti-shock body — Anti shock bodies or Küchemann carrots are pods placed at the trailing edge of a subsonic aircraft s wings in order to reduce wave drag, thus improving fuel economy, as the aircraft enters the transonic flight regime (Mach 0.8–1.2). Most jet… …
