High frequency induction plasma heating wind tunnel

Abstract

A high frequency induction plasma heating wind tunnel is used for a nonequilibrium thermal environment and deep space exploration research. The heating wind tunnel comprises a plasma generator, a jet pipe, a test segment, a diffusion segment, a cooler, a vacuum set and an assisting system. Working gas is heated by the plasma generator, acts on a model of the test segment under the effect of the jet pipe, and is discharged outside via the vacuum set by being pressurized by the diffusion segment and cooled by the cooling segment. The high frequency induction plasma heating wind tunnel is a ground simulation apparatus that can provide a chemically pure, high temperature and high speed air flow environment, and can meet requirements of gas components for deep space exploration research.

Description

technical field [0001] The invention relates to the field of deep space exploration, in particular to a plasma heating wind tunnel in the field of aerodynamic thermal protection. Background technique [0002] With the development of aerospace technology, human beings are more and more willing to explore deep space, and the requirements for aerothermal ground simulation technology are also getting higher and higher. As early as 1964, the United States began to explore Mars, and at the same time, research on the exploration of other planets was also underway. my country's deep space exploration started relatively late, but in recent years, with the enhancement of comprehensive national strength and the deepening of aerospace research, the demand for deep space exploration has also become higher and higher.

Problems solved by technology

In the traditional arc wind tunnel, the DC arc heating gas is generally used to simulate the thermal environment of the aircraft re-entry into the atmosphere. The gas medium used is mainly air. Due to the inherent electrode burning phenomenon of the arc heater, the DC arc wind tunnel pollutes the high-temperature flow to a certain extent. field, which has an impact on the research on the real gas effect of heat-resistant materials and the research on the catalytic effect of the wall surface
