Shock tube — A shock tube is a device used primarily to study gas phase combustion reactions. Shock tubes (and related shock tunnels) can also be used to study aerodynamic flow under a wide range of temperatures and pressures that are difficult to obtain in… … Wikipedia
Shock diamond — [ Pratt Whitney J58 engine on testbed with full afterburner] Shock diamonds (also known as Mach diamonds or Mach disks) are a formation of shock waves in the exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket … Wikipedia
Wave — A wave is a disturbance that propagates through space and time, usually with transference of energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic… … Wikipedia
Rocket engine — RS 68 being tested at NASA s Stennis Space Center. The nearly transparent exhaust is due to this engine s exhaust being mostly superheated steam (water vapor from its propellants, hydrogen and oxygen) … Wikipedia
Compressible 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… … Wikipedia
Avalanche transistor — An Avalanche Transistor is a bipolar junction transistor designed for operation in the region of its collector current/collector to emitter voltage characteristics beyond the collector to emitter breakdown voltage, called avalanche breakdown… … Wikipedia
