2022年10月5日 · There are five common types of hypersonic wind tunnels. Quiet tunnels are perhaps the most sought after type. Quiet tunnels are so-called because they are capable of flowing air at hypersonic velocities without the turbulence created by the boundary layer that develops at such speeds.

The Naval Research Laboratory (NRL) Hypersonic Wind Tunnel is a long-duration mid-size aerodynamics test facility capable of real-time altitude and speed variation. The range spans sea level to...

2024年3月14日 · Mechanical engineers at Colorado State University built a new hypersonic wind tunnel that will advance high-speed military, space, and commercial transportation. The tunnel is one of about 10 devices in use across the nation, giving CSU distinctive research capabilities similar to NASA and the U.S. Air Force.

The LAL consists of three hypersonic blow-down wind tunnels covering Mach numbers of 6 and 10 and unit Reynolds number ranges of 0.5 to 8.3 million per foot as well as a 60-ft Vacuum Sphere Test Chamber. LAL facilities are used to study and define the aerodynamic performance and aeroheating characteristics of flight vehicle concepts.
