System and method for simulating irradiation heating environment of hypersonic aircraft

Abstract

The invention disclosed a system and a method for simulating irradiation heating environment of a hypersonic aircraft. The system comprises an environment simulation chamber, an infrared lamp array, a laser heating unit and a vacuumizing unit. The infrared lamp array arranged on the inner wall of the environment simulation chamber is used for carrying out medium-high temperature heating on the whole aircraft or local parts of the aircraft, the environment simulation chamber is externally connected with the vacuumizing unit which is used for increasing and reducing pressure inside the environment simulation chamber, and the laser heating unit is arranged outside the environment simulation chamber and emits a laser beam which can penetrate through the glass which is arranged on the side wall of the environment simulation chamber so as to carry out ultrahigh temperature heating on the whole aircraft or the local parts of the aircraft. The infrared lamp array and a solid-state laser are adopted as heating sources, therefore, the large component of the aircraft even the whole aircraft can be tested, and the technology difficulty of height thermal environment comprehensive simulation is little; and the system has simple structure, and is more flexible.

Description

technical field [0001] The invention relates to the field of thermal environment simulation, in particular to a combined radiation heating environment simulation system applied to hypersonic aircraft thermal environment simulation tests. Background technique [0002] The thermal environment simulation test of the whole machine or partial parts of a hypersonic vehicle is an important basic test for the development of a hypersonic vehicle. Hypersonic aircraft in near space will encounter extremely high temperature and heat flux, which will have many adverse effects on the aircraft. For example: under high temperature conditions, the strength limit and elastic modulus of the material decrease, and the bearing capacity of the structure decreases; under the condition of rapid heating, a huge temperature gradient is formed inside the material, resulting in additional thermal stress, which affects the local or overall bearing capacity of the structure; Under the action of high tem...
