FIELD: pipes.
SUBSTANCE: invention relates to experimental aerodynamics, particularly to wind tunnels. Device comprises setting device, actuator, temperature, position and pressure sensors, as well as pressure regulator. Pressure regulator consists of adder of negative feedback by pressure, series-connected low-pass filter and facing object control model, closed by positive feedback through an adder model of control object. Controller inputs are connected to driving device and air pressure and temperature sensors in antechamber, temperature and air pressure in gas-holder, plunger position adjusting throttle and nozzle throat.
EFFECT: technical result consists in possibility of using the controller in whole range of allowable for WT values number M with high accuracy in automatic mode without correcting devices.
