FIELD: physics.
SUBSTANCE: device for determining static and dynamic characteristics of gas-dynamic objects consists of an aerodynamic tunnel housing in form of a pipe fitted with a flow modulator. The flow modulator consists of one rotary disc valve and a differential pressure measuring transducer. The device also includes a channel for generating test effects, a channel for measuring parametres of the test effects, a channel for controlling parametres of the analysed object, a preliminary digital processing channel and a channel for digital control of operation of the device. Said channels are connected to each other in a corresponding circuit.
EFFECT: higher efficiency of the device, higher accuracy, broader functional capabilities and more reliable functioning.
