Abstract

The invention discloses a no-pollution quick insert gas heating experiment device which belongs to the technical field of aerodynamic missile engine ground simulation experiment. The experiment comprises a graphite heat storage member, an electromagnetic induction coil and a pressure housing. The electromagnetic induction coil winds the graphite heat storage member. The electromagnetic induction coil is electrically connected with outer power distribution equipment. The graphite heat storage member is heated through electromagnetic induction. The graphite heat storage member and the outer electromagnetic induction coil are mounted in the pressure housing. Furthermore the air inlet channel and the air outlet channel of the graphite heat storage member penetrate the pressure housing. According to the experiment device, the graphite material is used as the heat storage member; the heat storage member is heated through the electromagnetic induction coil; after a preset temperature is reached, insert gas is introduced; the inert gas is heated by means of convection heat exchange between the surface of the heat storage member and the inert gas; and no-pollution heating to the inert gas can be quickly performed.

Description

technical field [0001] The invention belongs to the technical field of ground simulation tests of aircraft missile engines, and in particular relates to a test device for rapidly heating inert gas without pollution. Background technique [0002] There are many ways to simulate the high temperature environment on the ground test bench of the aircraft missile engine. At present, the most important ones are combustion heating method and convection heat exchange heating method. [0003] Combustion heating method: use air or oxygen-containing gas as the test working medium, and use alcohol, kerosene and other fuels to burn heat with oxygen to heat the incoming working medium; however, this heating method can only heat oxygen-containing gas, and the combustion produces A large amount of impurity gases such as water vapor and carbon dioxide have a great influence on the test results. [0004] Convective heat exchange method: use heat accumulator or heating body as heat source, de...
