Problems solved by technology

When the Mach number is greater than 7 and less than or equal to 10, the air flow of the wind tunnel is relatively small, the pressure level is high, and the heating temperature is high. During use, it is prone to failure due to the influence of high temperature and high pressure.
If a heater is used to meet both the large flow rate and high temperat

Abstract

The invention discloses a three-branch series connection type hypersonic wind tunnel overall structure, and the structure comprises branches dividing the Mach number simulation range of a hypersonic wind tunnel into three branches, wherein the three branches are the large-flow low-pressure cold air branch, the large-flow medium-temperature medium-pressure branch and the medium-small-flow high-temperature high-pressure branch respectively; the Mach number operation range of the large-flow low-pressure cold air branch is smaller than or equal to Mach number 4, the Mach number operation range of the large-flow medium-temperature medium-pressure branch is larger than 4 and smaller than or equal to 7, and the Mach number operation range of the medium-small-flow high-temperature high-pressure branch is larger than 7 and smaller than or equal to 10. According to the three-branch series connection type hypersonic wind tunnel overall structure provided by the invention, the advanced hypersonic wind tunnel requirement of wide parameter simulation can be realized through a step-by-step implementation mode; the wind tunnel operation state is convenient to switch, the wind tunnel layout is concise, and wind tunnel safe operation and standardized management are facilitated.

Description
