民用飞机辅助动力装置排液验证试验方法研究

民用飞机辅助动力装置(APU)排液验证试验涉及APU 系统、总体布置及气动外形设计、APU 舱结构和后尾锥结构等多个专业,属于整机集成验证问题,是国内外民机取证过程中的共性难点。对民用飞机APU 排液验证试验方法进行了研究,给出了APU 排液地面试验和飞行试验时相关测试改装、试验方法的技术要点以及试验结果的符合性判据。

Research on APU Fluid Drainage Certification Test Methods of Civil Aircraft

Auxiliary power unit (APU) fluid drainage certification test for civil aircraft is one of the most difficult issues during civil aircraft certification. As an aircraft integration test, it is involved with APU system design, aircraft general layout design, aerodynamic design, APU compartment and tailcone structure design, etc. The paper studies auxiliary power unit (APU) fluid drainage certification test , and the key technology points for relevant test methods, modification and instrumentation and the compliance criteria during ground and flight tests are obtained.
