FIELD: physics; control.SUBSTANCE: invention relates to control systems in experimental aerodynamics, particularly wind tunnels with controlled nozzles. The apparatus has a controller for controlling drives of driven series of flexible walls of the nozzle, drives for controlling flexible walls of the nozzle, digital feedback sensors, as well as a command device, a digital unit for calculating the given position of driven series in a function of the measured position of the drive series, as well as a digital sensor of the position of the drive series and an operating mode switch. The digital unit for calculating the given position of driven series in a function of the measured position of the drive series is connected in series to the sensor of the potion of the drive series and the controller for controlling drives of driven series of flexible walls of the nozzle through the operating mode switch.EFFECT: design of a device which enables restoration of the nozzle of an wind tunnel in automatic mode and high accuracy of installing the nozzle.1 dwg |
