Nozzle Performance Test Module

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 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.
