摘　　要：辅助动力进排气系统性能是辅助动力系统设计过程中面临的关键工程技术问题。本文对飞机辅助动力装置进排气系统简化后进行三维流动数值仿真,分析了不同工况下飞机辅助动力装置进排气系统对辅助动力装置性能的影响。研究表明:在地面工况和高空飞行工况下,两侧开门式辅助动力装置进排气系统可以满足辅助动力装置进排气流量及总压损失需求,不会对辅助动力装置在不同状态下的正常起动和工作产生影响。The intake and exhaust performance of Auxiliary Power Unit(APU)is a key engineering and technical issue faced in the design process of APU.This article simplifies the intake and exhaust systems of aircraft auxiliary power devices and conducts three-dimensional numerical simulation to analyze the impact of the intake and exhaust systems of aircraft auxiliary power devices on their performance under different operating conditions.Research has shown that under ground and high-altitude flight conditions,the intake and exhaust systems of the two side open door auxiliary power device can meet the requirements of the intake and exhaust flow rate and total pressure loss of the auxiliary power device,without affecting the normal start and operation of the auxiliary power device in different states.
