Summary:This paper presents the effect of temperature inside the settling chamber of a hypersonic wind tunnel which is a test facility used to study the effect of aerodynamic forces on the specimen under test. Regulation of pressure inside the settling chamber is a very important task for the efficient operation of the tunnel system. The effects of aerodynamic forces and temperature are to be considered for the flight vehicle design and to be tested in the test section of the tunnel system. Here the stability analysis and the open loop response of the nonlinear model of the hypersonic wind tunnel is determined. The response of the settling chamber pressure incorporating the variation in temperature in all three vessels, high pressure vessel, heater and settling chamber is also obtained.
