Reverse thrust testing technique in the 8m×6m Low Speed Wind Tunnel of CARDC

  • 摘要: TPS(涡扇动力模拟器)试验技术是风洞中模拟发动机反推力状态最有效的手段。开展反推力试验的目的是获得反推力发动机对飞机气动特性的影响,确定反推力发动机的再吸入速度边界。为满足我国大飞机研制的试验技术需求,中国空气动力研究与发展中心在8米×6米风洞发展了全模TPS反推力试验技术。自主研制了TPS反推力试验专用的高精度六分量杆式应变天平、大流量空气桥和流量控制单元、TPS监视报警系统、数据采集系统、综合显示系统等TPS反推力试验系统,制定了试验模拟准则、试验流程和试验方法,建立了完善的全模TPS反推力试验技术。利用TPS反推力试验技术,开展了国内首期全模TPS反推力风洞试验,研究了某型飞机反推力发动机的再吸入特性,获得了反推力发动机的再吸入速度边界。

     

    Abstract: The turbine powered simulator (TPS) testing technique is the prime choice for simulation of reverse thrust of engines in wind tunnel. The purposes of the reverse thrust test are to obtain the impact of reverse thrust on the aircraft aerodynamics property and determine the re-ingestion velocity. To meet the needs of testing technique of large aircraft, CARDC built up a testing technique to simulate the reverse thrust of engines with turbine powered simulators (TPS), the beam balance, air bridge, mass flow controlling units, surveillance and alarm system, data processing system and integrated display system were developed, and the similarity criterion, testing procedure and methods were formulated as well. The first domestic low speed reverse thrust test with whole model was carried out in the 8m×6m Wind Tunnel. The test investigates the reverse property of an aircraft and gain re-ingestion velocity, and test results indicated that re-ingestion velocity of the aircraft is around 48m/s.
