Abstract

The invention provides a high-temperature combustion-gas flow supersonic wind tunnel test system and relates to the technical field of aircraft thermal protection ground test. The system comprises a heater, a supersonic nozzle, a test cabin, a diffuser and an exhaust system. One end of the heater is connected with an external energy system; one end of the supersonic nozzle is fixedly connected with the heater, and the other end of the supersonic nozzle is fixedly connected with the test cabin; the diffuser is fixedly arranged at one end of the test cabin; and one end of the exhaust system is fixedly connected with the diffuser, and the other end of the exhaust system is connected with the outside world directly. The high-temperature combustion-gas flow supersonic wind tunnel test system is a system having hundred-megawatt power and meter-scale jet size, and the power thereof reaches more than 200 megawatts, and the jet size reaches 1.5 m; and aircraft thermal protection system global and regional 1:1 large-size model heat check can be realized.

Description

technical field [0001] The invention relates to the technical field of aircraft heat-resistant ground tests, in particular to a high-temperature gas flow supersonic wind tunnel test system. Background technique [0002] Hypersonic aircraft will be subjected to severe aerodynamic heating during flight, and the heat protection system plays a decisive role in the development of the aircraft. It is an indispensable link in the development process of the aircraft heat protection system to carry out thermal environment simulation assessment and verification on the ground test of the aircraft heat protection system. [0003] At present, the domestic test systems for thermal assessment of aircraft heat protection systems mainly include arc wind tunnels and gas flow free jet test benches. The power of the arc wind tunnel is on the order of ten megawatts, the scale of the gas flow free jet test bench is small, and the outlet pressure of the nozzle is generally atmospheric pressure. ...
