摘要
为开展大涵道比涡扇发动机反推力装置的性能试验,设计了涡扇发动机反推力装置模型试验台。该试验台具有六分力测量、外流场测量、内涵气体加温等功能,以及双涵道喷管矢量推力和性能测量能力。通过直接排气和反推力排气试验对该试验台的主要功能进行了验证,结果表明:试验台满足最大排气流量60 kg/s的双涵道喷管直接排气和反推力排气性能试验要求,内涵可加温到650℃,测量精度较高,可用于航空发动机反推力装置及功能喷管、排气装置等部件的基础试验。
In order to carry out the performance test of the thrust reverser of the high bypass ratio turbofan engine,the model test-rig of the thrust reverser of the turbofan engine was designed.The test-rig has the functions of six-component force measurement,outflow field measurement,intension gas heating and so on,as well as vector thrust and performance measurement capability of dual separate flow nozzle.The main functions of the test-rig were verified by the test of direct exhaust and thrust reverser exhaust.The results show that the test-rig can meet the performance test requirements of direct exhaust and thrust reverser exhaust of dual separate flow nozzle with maximum exhaust flow rate of 60 kg/s,the core stream can be heated to 650℃,and the measurement accuracy is high,which can be used in the basic test of aeroengine thrust reverser and functional nozzle,exhaust system and other components.
