The test apparatus and the test method for the heat insulation performance of the honeycomb panel in the invention have the following advantages: small energy consumption, simple operation, capacity of convenient and rapid changing of a temperature and capability of accurate and effective testing of the heat insulation performance of the honeycomb panel.

Description

technical field [0001] The invention relates to a heat insulation performance test device, in particular to a honeycomb panel heat insulation performance test device and a test method thereof. Background technique [0002] Now major countries in the world are competing to develop hypersonic aircraft in order to achieve rapid global reach and effective penetration in modern warfare, so as to strike combat targets quickly and accurately. As the flight speed of hypersonic vehicles is greatly increased, the aircraft will face serious aerodynamic heating problems. Aerodynamic heating is caused by the friction of the gas against the surface of the aircraft against the aircraft. The gas close to the aircraft undergoes a complex heat exchange process on the surface of the aircraft structure. This process includes heat conduction between gas molecules, diffusion heat transfer of gas components, gas decomposition, and heat flow exchange caused by gas atomic recombination. According ...
