A high enthalpy wind tunnel is intended to study flow of air around objects moving at speeds much faster than the local speed of sound (hypersonic speeds). " Enthalpy " is the total energy of a gas stream, composed of internal energy due to temperature, the product of pressure and volume, and the velocity of flow.
NASA Langley's Hypersonic Facilities Complex, 1969. A hypersonic wind tunnel is designed to generate a hypersonic flow field in the working section, thus simulating the typical flow features of this flow regime - including compression shocks and pronounced boundary layer effects, entropy layer and viscous interaction zones and most importantly high total temperatures of the flow.
High-speed flight represents the next frontier. ... and is now home to the world’s most powerful hypersonic wind tunnel, ... launched spaceplane design in this tunnel that has been designed for ...
High subsonic wind tunnels, between Mach 0.4 and 0.75, and transonic wind tunnels, between Mach 0.75 and 1.2, are designed on the same principles as the subsonic wind tunnels. Testing at transonic speeds presents additional problems, mainly due to the reflection of the shock waves from the walls of the test section.
A university hopes a £2m investment in wind tunnels will put it at the forefront of aerospace teaching facilities. ... The university is currently installing a new bespoke high-speed impact ...
A supersonic wind tunnel is a wind tunnel that produces supersonic speeds (1.2<M<5) The Mach number and flow are determined by the nozzle geometry. The Reynolds number is varied by changing the density level (pressure in the settling chamber). Therefore, a high pressure ratio is required (for a supersonic regime at M=4, this ratio is of the ...
Aerospace and defense companies use Florida State University's wind tunnel to test their developing aircraft. FSU's Polysonic Wind Tunnel, 'a crown jewel,' tests aircraft from across the nation ...
