Problems solved by technology

[0004] However, during the high-temperature thermal strength test of the aircraft, since the alloy steel or 304 stainless steel joints will block the radiation heating of the test piece, after the test, there will be obvious unheated areas on the surface of the test piece, which seriously affects the high temperature of the aircraft. Accuracy of heat strength test

Description

technical field [0001] The invention relates to the technical field of aircraft testing, in particular to a static load loading system and a method thereof in a high-temperature thermal strength test for aerospace aircraft testing. Background technique [0002] The aircraft high temperature thermal strength test is a key step in the aircraft structure test. The aircraft high temperature thermal strength test can observe and study the mechanical properties and resistance to damage of the aircraft structure or components in the thermal environment. During the test, it is necessary to simulate and fly on the ground. For the thermal load environment equivalent to the process, in addition to static, dynamic and fatigue tests in the thermal environment, it is also necessary to study the heat transfer test of the heat transfer characteristics of the structure, the thermal insulation test, the ground simulation test of ablation, and the creep. Tests, etc., according to the differenc...
