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.
