WebThe shock tube is an instrument used to replicate and direct blast waves at a sensor or a model in order to simulate actual explosions and their effects, usually on a smaller scale. … Web11. apr 2024 · The tunnel is capable of running for up to 20 s; its working gas is the air from atmosphere. The supersonic nozzle was designed to use the method of characteristics … Reflected shock tunnels heat and pressurize a stagnant gas by using shockwaves that are redirected back into the center; this excites the gases and produces movement, heat, and pressure. The gases are then released and expanded through the nozzle and into the test chamber. Zobraziť viac In aeronautics, expansion and shock tunnels are aerodynamic testing facilities with a specific interest in high speeds and high temperature testing. Shock tunnels use steady flow nozzle expansion whereas expansion … Zobraziť viac Thin-film heat transfer gauge When the gauge is heated, the resistance changes; this causes a change in voltage, which is used to calculate the amount of heat transferred into … Zobraziť viac Expansion tunnel Expansion tunnels use a dual-diaphragm system where the diaphragms act as rupture discs, or a pressure relief. The tunnel is … Zobraziť viac During the expansion process, a variety of test are run to analyze the aerodynamic and thermal properties of the test vehicle. Skin friction The drag that is created when an object travels … Zobraziť viac Hypervelocity Expansion Tube (HET) The HET is one of the shock tunnels in the Caltech Hypersonics group at the California Institute of Technology directed by Professor Joanna Austin.
