ONERA Modane S2MA wind tunnel [77] Operational Supersonic France Continuous-flow wind tunnel, Variable pressure, Mach 0.1 to Mach 3.0. PHEDRA (Arc-jet) high enthalpy wind tunnel [78] Operational Diameter 4.5 m (15 ft) by 2.1 m (6 ft 11 in)
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.
Since then, China has continued to advance its science and technology and is now home to the world’s most powerful hypersonic wind tunnel, the JF-22, which can simulate the conditions in which a ...
A drawing defining the geometry of the AGARD-B standard model and its sting fixture; all dimensions are relative to body diameter D (dimensions according to [1]) Theodore von Kármán, left, is joined by Air Force and NASA officials while inspecting two of the models used in the high velocity, high altitude wind tunnels at Arnold Air Force Base.
Cryogenic tunnels: Test gas is cooled down to increase the Reynolds number. The European transonic wind tunnel uses this technique. High-altitude tunnels: These are designed to test the effects of shock waves against various aircraft shapes in near vacuum.
It is an open-jet wind tunnel. Dimensions: The wind tunnel is composed of 3 parts: a settling chamber: length of 2.6 m, internal diameter of 1.2 m. It is equipped with a flow breaking cone. a cylindrical test chamber: length of 3.5 m, diameter of 2 m. a diffusor going to the pumping room: length of 10m and diameter of 1.4 m. Scheme of the wind ...
16S is a supersonic wind tunnel that can be configured for Mach numbers from 1.5 to 4.750. The test section is also 16-foot-square and 40-foot long. The facility can simulate unit Reynolds numbers from approximately 0.1 to 2.4 million per foot or altitude conditions from 43,000 to 154,000 feet. Currently 16S is in the standby state.
