Abstract

The invention relates to the technical field of system robustness analysis and optimization design, in particular to an anti-icing cavity structure reliability design method, which comprises the stepsof establishing a structure model of an anti-icing cavity, and editing the structure model according to a preset value set for a preset structure variable to obtain at least one to-be-selected structure model; performing numerical simulation on the at least one to-be-selected structure model to determine an initial structure model; based on the influence of each preset structure variable on the failure probability of the initial structure model, determining a main optimization variable and an auxiliary optimization variable in the preset structure variables; and determining the value ranges of the main optimization variable and the auxiliary optimization variable according to a preset rule, and performing optimization design on the initial structure model based on the value ranges. According to the method provided by the embodiment of the invention, the initial structure model can be optimized in a targeted manner, so that better anti-icing and deicing effects are obtained.

Description

technical field [0001] The present disclosure relates to the technical field of system robustness analysis and optimization design, and in particular, relates to a reliability design method of an anti-icing chamber structure. Background technique [0002] With the development of the large aircraft project in our country, the research on the wing aerothermal anti-icing system has been paid more and more attention. As the core component of the wing aerothermal anti-icing system, the anti-icing cavity directly affects the anti-icing and de-icing effect of the aircraft. [0003] Since the anti-icing chamber uses the high-temperature and high-pressure engine bleed air to eject the air after heat exchange with the icing protection surface, so that the pressure and temperature of the mixed air meet the anti-icing and deicing requirements, and then achieve the purpose of anti-icing and deicing At the same time, for the performance of the engine, the bleed air volume of the engine o...
