GAS-DYNAMIC TESTING DEVICE Russian patent published in 2018 - IPC G01M9/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of industrial aerodynamics and can be used for gas-dynamic testing of aviation and rocket technology. Device comprises a test chamber with an aerodynamic nozzle, source of compressed air with a high-pressure line, system for regulating the supply of compressed air with adjustable valves, pressure sensors, a temperature sensor and an air flow regulator installed in the high-pressure line, gas generator with a mixing tank, fuel injectors and an ignition system connected by an inlet to the high pressure line, and the outlet to the inlet of the aerodynamic nozzle of the test chamber, fuel supply system, connected to the fuel injectors and having a fuel flow controller, and an oxygen supply system connected to the mixing tank and having an oxygen flow regulator. It is also provided with a source of constant pressure of neutral gas, regulators of fuel and oxygen consumption are made in the form of controlled reduction valves, the control cavity of each of which is connected to a source of constant pressure of neutral gas through an additional pneumatic reducer, an adjustable valve and a receiver connected to the atmosphere through additional controlled valves.

EFFECT: technical result consists in increasing the accuracy of regulation of all components supplied to the gas generator and ensuring the explosion-proof operation of the device.
