The optimum hypersonic wind tunnel

14th Aerodynamic Testing Conference, 1986
The capabilities of existing hypersonic wind tunnels in the U.S. are assessed to form a basis for recommendations for a new, costly facility which would provide data for modeling the hypervelocity aerodynamics envisioned for the new generation of aerospace vehicles now undergoing early studies.

Laser-Heated Hypersonic Wind Tunnel

AIAA Journal, 1973
Typical stagnation conditions required to simulate the orbital re-entry corridor are P0 > 1000 atm and T0 > 5000°K. Although it is not feasible to have such stagnation conditions in a reservoir operating under nearly continuous conditions, it is feasible to obtain high stagnation temperatures in a gas flowing from a relatively cool high-pressure ...

Condensation in hypersonic nitrogen wind tunnels

16th Aerodynamic Ground Testing Conference, 1990
Experimental observations and a theoretical model for the onset and disappearance of condensation are given for hypersonic flows of pure nitrogen at M = 10, 14 and 18. Measurements include Pitot pressures, static pressures and laser light scattering experiments.

High-Sensitivity Atomic Layer Thermopile Heat- Flux Sensor and Its Application in Hypersonic Low-Density Wind Tunnel Tests

IEEE Transactions on Instrumentation and Measurement
Measuring the heat-flux density is one of the main tasks in the research field of hypersonic experimental aerodynamics. Considering the fact that refined wind tunnel tests require small-sized sensors, and the sensitivity of atomic layer thermopile (ALTP)

Tomographic Reconstruction of Hypersonic Aircraft Flowfields in Large-Scale Wind Tunnel Experiments

AIAA Journal
Three-dimensional flowfield features around a hypersonic aircraft model were reconstructed using a computed tomography background-oriented schlieren technique. Datasets of projection images were acquired in hypersonic wind tunnel experiments conducted at

Supercooling in hypersonic nitrogen wind tunnels

Journal of Fluid Mechanics, 1994
Recent experimental observation of supercooling in large hypersonic wind tunnels using pure nitrogen identified a broad range of non-equilibrium metastable vapour states of the flow in the test cell. To investigate this phenomenon a number of real-gas effects are analysed and compared with predictions made using the ideal-gas equation of state and ...
