摘　　要：根据中国民用航空规章第25部《运输类飞机适航标准》(CCAR-25-R3)相关条款的要求,烟雾探测系统必须在起火后1 min内,向飞行机组给出目视指示。然而条款中未明确给出烟雾探测系统试验中所用烟雾量的大小。如何科学、合理的确定烟雾探测试验中烟雾量的大小是烟雾探测系统合格审定试飞的关键。通过搜集资料,梳理了国外对于发烟材料以及烟雾量大小的研究方法;通过借鉴空客公司烟雾探测试验烟雾量大小的确定方法,在实验室中对某型货舱烟雾探测系统功能试验中的烟雾量大小进行了研究,为该货舱烟雾探测系统功能飞行试验铺平了道路。According to China＇s Civil Aviation Regulations Part 25 ＂ transport category aircraft airworthiness standards＂（ CCAR-25-R3） related provisions,smoke detection system must give a visual indication to the flight crew within one minute after the fire. However,the terms are not explicitly given the amount of smoke in the test of the smoke detection system. How scientific and reasonable test to determine the amount of smoke is the key to the smoke detection system certification test flight. By gathering information abroad for smoke material and the research methods of the amount of smoke and by determining the method Airbus smoke detector test aerosol to the size of the drawing,research on the amount of smoke of a certain type of cargo smoke detection system functions test in the laboratory,paving the way for the cargo compartment smoke detection system function flight test.
