Hypersonic Piston Gun Tunnel
2012-01-13 | admin
FD-20, FD-22 are hypersonic impulsive gun tunnels with Mach number 5-25. The diameter of nozzle exit is φ0.4~φ0.5m. The total pressure and temperature can reach to 400Mpa and 3000K respectively while (Re)max=6*107/m. The main tests are as following: pressure, force, and thermal transferring measurements of hypersonic flight vehicle models, stage separating test, cold and hot jet simulation, engine ignition, the interferences of shock waves, flow visualization, etc.
