Abstract

The invention discloses a novel exhaust system, which includes a vacuum spherical tank (1), a centrifugal vacuum pump (2), a regulating valve (3) and a vacuum switching valve (4). The vacuum switching valve (4) is located in the vacuum spherical tank ( 1) and the centrifugal vacuum pump (2). The invention has the beneficial effects of long continuous operation time, stable airflow pressure in the flow field of the control wind tunnel test section, accurate repetition of air flow state parameters in a given test section, and improved wind tunnel operation test efficiency.

Description

technical field [0001] The invention relates to the technical field of a vacuum exhaust system for wind tunnel tests, in particular to a novel exhaust system. Background technique [0002] A wind tunnel is a pipeline-shaped experimental device that artificially generates and controls airflow to simulate the flow of air around an aircraft or object, and can measure the effect of airflow on an object and observe physical phenomena. It is the most commonly used and most effective for aerodynamic experiments. Tool of. The hypersonic wind tunnel can take into account the environment of supersonic flight and the time required for dynamic pressure to a large extent, and can simulate different combinations of total pressure parameters to meet the basic requirements of the flight environment of supersonic vehicles at different flight altitudes. The hypersonic wind tunnel is mainly composed of a gas source system, a combustion heater, a nozzle, a test section, a diffuser, a vacuum ba...
