摘　　要：直升机传动系统润滑失效将导致传动部件在短时间内进入干运转状态,进而使传动失效,引发灾难。本文以运输类旋翼航空器传动系统中使用压力润滑的减速器为研究对象,以其润滑失效时的适航符合性验证为研究内容,通过对适航规章进行解析,结合国外适航当局最新修订动态以及型号经验,给出了一种适合我国民用直升机传动系统压力润滑减速器润滑失效的适航符合性验证方法,并结合实际案例进行验证,为我国民用直升机压力润滑减速器润滑失效的适航验证提供借鉴。If the rotor drive system loses lubrication,transmission parts would get into the loss of oil operation condition in a short time,and then lose the ability to transmit power,causing a catastrophic accident.This paper researches on the airworthiness compliance verification method used for pressurized lubrication gear box of transport category rotorcraft transmission when loss of oil.Based on the analysis on airworthiness regulations and the latest revised developments of foreign airworthiness authorities,a compliance verification method is proposed.The method is suitable for the loss of oil operation of pressurized lubrication gear box of civil helicopter.Finally,the effectiveness of the proposed method is verified by the case.The proposed method provides reference for the verification of loss of oil operation of pressurized lubrication gear box of civil helicopter.
