摘　　要：基于对中国民用航空局(CAAC)运输类飞机适航标准和美国联邦航空管理局(FAA)咨询通告的分析、解读,分别从工程试验与适航验证两个方面,研究了溅水试验程序、试验水池方案设计与滑行速度测量与控制技术,制定了符合适航标准体系的运输类飞机动力装置溅水试验审定程序,以ARJ21-700型支线飞机合格审定试飞为平台,完整进行了相关试验验证。结果表明:所设计的溅水试验程序合理可行,能够完整地验证运输类飞机在机场跑道积水环境下动力装置对适航标准体系的符合性;试飞结果表明CF34-10A发动机配装ARJ21-700型飞机在机场积水环境下起飞构型临界滑行速度为166.6 km/h,发动机风扇、压气机及动力涡轮前温度最大波动值分别为5.1%、1.7%和39℃;在飞机着陆构型下,发动机慢车状态相对于最大反推力状态工作稳定性较好,能够满足适航标准规定;项目形成溅水试验程序和技术为后续C919、C929等运输类飞机动力装置相关试验提供了直接的支持。On the basis of analyzing and interpreting the Chinese civil regulations transport airworthiness standards of Civil Aviation Administration of China(CAAC)and advisory circular of Federal Aviation Administration(FAA),the water ingestion test program,test pool scheme and landing speed measurement and control technology was studied and designed from two aspects of engineering test and airworthiness verification.Based on the airworthiness standard system,the procedure of transport aircraft power system water ingestion test was developed and applied in the ARJ21-700 aircraft flight test.The results showed that the designed water ingestion test procedure was reasonable and feasible,and it was able to verify power systemcompliance with standards completely when the transport aircraft passed through the water contaminated runway;the critical speed of ARJ21-700 aircraft equipped with CF34-10 A engine was 166.6 km/h in aircraft taking off and slipping through the water contaminate runway;the maximum fluctuations of the rotation rate of fan and compressor,and inter turbo temperature were 5.1%,1.7%and 39℃.The performance of engine was better in idle state compared with maximum reverse thrust state in the aircraft landing and slipping through the water contaminated runway.So it could meet the airworthiness standard.The procedure and technology provide a direct support for the power system water ingestion test of C919,C929 and other transport aircrafts.
