Embodiment Construction

[0017] The present invention will be described in further detail below with reference to the accompanying drawings.

[0018] The layout scheme of the present invention is as Figure 4 shown. The heat exchanger 7 includes an intermediate channel and a peripheral channel surrounding the intermediate channel. First, the high-pressure gas from the gas tank 1 is sent into the peripheral channel of the heat exchanger 7, and then sent into the heater 2 by means of a gas pipeline. In the heater 2 The heated high-pressure gas is sent into the stable section 3, flows through the nozzle 4, the test section 5 and the super-expansion section 6 in turn, flows into the middle channel of the heat exchanger 7, and then passes through the ejector 8 and the water ring pump group 9 is exhausted into the atmosphere. Alternatively, via the vacuum bulb 10 , it is exhausted to the atmosphere by the vacuum pump system 11 .

[0019] This layout is an improvement on the existing layout. The main chan...

Abstract

The invention provides an energy-saving environment-friendly layout of a large-scale routine hypersonic wind tunnel. The system comprises a gas tank, a heater, a stabilization segment, a jet pipe, a test segment, an ultra-expanding segment and a heat exchanger, wherein the stabilization segment, the jet pipe, the test segment and the ultra-expanding segment are successively connected to form a major test wind tunnel assembly, the heat exchanger comprises an intermediate channel and a peripheral channel encircling the intermediate channel, an outlet of the ultra-expanding segment communicates with the intermediate channel of the heat exchanger, the gas tank communicates with the peripheral channel of the heat exchanger, and high-pressure gas in the gas tank is sent into the heater via the peripheral channel of the heat exchanger by means of a gas pipeline, then is sent into the stabilization segment after passing through the heater and is discharged through flowing through the intermediate channel of the heat exchanger after being tested in the major assembly of a test wind tunnel. According to the invention, energy consumption is reduced, the operation cost is decreased, at the same time, the influence on the environment is reduced, and the problems of large exhaust noise and waste of afterheat of a conventional hypersonic wind tunnel can be solved.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly layout of a large conventional hypersonic wind tunnel. Background technique [0002] The conventional hypersonic wind tunnel is a hypersonic wind tunnel with pure air as the working medium and heated by convection. It is an essential test equipment for the development of hypersonic aircraft. With the continuous development of hypersonic vehicles, conventional hypersonic wind tunnels have been undergoing transformation and construction, and the scale of equipment is getting larger and larger. In terms of the outlet size of the wind tunnel nozzle, the conventional hypersonic wind tunnel has developed from the initial 200-300mm level to the current 1000-1200mm level. Looking forward to the development of hypersonic vehicles in the future, conventional hypersonic wind tunnels of the order of 2400-3000mm are needed. [0003] The development of conventional hypersonic wind tunnel technology...
