Abstract

Abstract:

In order to improve the working performance of the pneumatic safety valve for aviation propulsion system, the AMESim numerical model of the high-pressure gas line of a double-stage gas pressure reducer and a safety valve was established. A safety valve test performance experimental bench was built to verify the accuracy of the model, and the influence law of structural parameters on the characteristics of the safety valve was studied. A significant regression model of structural parameters and safety valve pressure overshoot and response time was established using response surface methodology (RSM). The significant differences in the effects of structural parameter interactions on safety valve pressure overshoot and response time were investigated using Analysis of Variance (ANOVA). The parameters of inlet length, inlet diameter and spring stiffness were optimized based on an Adaptive Range Multi-objective Genetic Algorithm (ARMOGA). The results of the study show that the influence of inlet length, inlet diameter, and spring stiffness on overshoot and response time decreases in descending order, with the interaction between inlet length and diameter being the most significant. The best performance of the safety valve is achieved when the inlet length, inlet diameter and spring stiffness are 14.587 8 mm, 14.898 0 mm and 48.966 8 N/mm, respectively, and the optimized overshoot is reduced by 6.917% and the response time is reduced by 6.383%.

Key words: aviation propulsion system, pneumatic safety valve, structural parameters, overshoot and response time, multi-objective optimization
