Description

technical field [0001] The invention relates to a dynamic oxidation ablation test method and device for simulating the environment of an engine combustion chamber, and belongs to the technical fields of engineering materials, structural deformation and mechanical experiments. Background technique [0002] The engine is the core component of the aircraft and one of the decisive factors for the maneuverability, range, reliability, economy and environmental impact of the aircraft. The service environment of aeroengines is harsh and the factors are complex, and there is a coupling effect in the response of materials to the environment, rather than the superposition of the results of a single environment. For this reason, in the corresponding major material research plans of various countries, the environmental performance simulation of materials is taken as the main content, such as the aircraft composite material plan formulated by the United States in 1988, and the advanced th...
