Nozzle Performance Test Module
A series of convergent and convergent-divergent nozzles may be installed in one of two locations in a high pressure measuring chamber. A pressure regulator, throttle valve and back pressure valve allow the air flow rate, inlet and discharge (or back) pressure to be varied.
Standard unit includes convergent Ã¢â¬â divergent ducts designed to produce Mach 1.0 at the throat and supersonic velocities downstream.
Inlet and outlet air pressures, temperatures and air flow rate are recorded by a combination of instrumentation on the Compressible Flow Range base unit and the optional module.
