民用飞机动力装置短舱排液适航验证试验研究

摘要

In order to demonstrate the Civil Aircraft Powerplant System nacelle drainage compliance with CCAR25.1187(a) (c) and CCAR25.1091(d)(1), the ground certiifcation test(MOC5) and lfight certiifcation test(MOC6) need to be conducted to show that the flammable fluid from the leakage zone of the compartment could be discharged safely without accumulation and no discharged lfuid will cause an additional hazard. A brief introduction of nacelle drainage system used for civil aircraft is given, and the test requirement, test plan and test result acceptance criterion of the nacelle drainage MOC5 and MOC6 tests are provided. Methods presented herein provide a valid approach and guidance for CCAR25.1187(a)(c) and CCAR25.1091(d)(1) compliance demonstration using MOC5 and MOC6.%为验证民用飞机动力装置短舱排液满足CCAR25.1187(a)(c)和CCAR25.1091(d)(1)条款的要求，需进行地面验证试验（MOC5）和飞行验证试验（MOC6），以证明动力装置舱内泄漏的可燃液体能被安全地排出机外而无积存，且排出时不会产生其他危险。在介绍某型民用飞机短舱排液系统功能和结构组成的基础上，给出了短舱排液MOC5和MOC6试验的试验要求、试验方案和试验结果可接受判据，为CCAR25.1187(a)(c)和CCAR25.1091(d)(1)条款的地面和飞行验证试验提供了有效途径，对飞机型号合格审定中有关短舱排液验证试验的相关工作具有指导意义。
