摘　　要：针对航空发动机全流程测量中高温燃气流场测试问题,研制旋转式多截面多参数流场扫描测量装置。使用设计的旋转扫描测量段替代某型航空发动机原混合扩压段,通过控制测量段旋转实现周向测点加密,在航空发动机涡轮出口、加力燃烧室进口同时测量温度场、压力场、速度场、方向场等参数。开展试验验证了旋转扫描测量装置设计、温度/压力/速度多场同步测试布局设计、探针可靠性设计、大偏角高温燃气温度精确测量、大偏角复杂三维流场测量方案的可行性,之后在某型航空发动机整机试验工况下开展测试,验证了旋转式多截面多参数流场扫描测量装置的实际应用效果,为航空发动机性能评定、部件匹配研究工作提供了重要技术支撑。In order to solve the problem of high temperature gas flow field test in the whole process measurement of aero engine,a rotating multi-section and multi-parameter flow field scanning and measurement device was developed.The designed rotary scanning measurement section was used to replace the original hybrid diffuser section of a certain type of aero engine,the circumferential measurement point encryption was realized by controlling the rotation of the measurement section,and the temperature field,pressure field,velocity field,direction field and other parameters were measured at the turbine outlet and afterburner inlet of the aero engine at the same time.The feasibility of the design of the rotary scanning measurement device,the layout design of the temperature/pressure/velocity multi-field synchronous test,the reliability design of the probe,the accurate measurement of the temperature of high-temperature gas with a large declination angle,and the complex three-dimensional flow field measurement scheme with a large declination angle were verified by experiments.Then,tests were conducted under the test conditions of a certain type of aircraft engine to verify the practical application effect of the rotating multi-section and multi-parameter flow field scanning measurement device.This study provides important technical support for the performance evaluation and component matching research of aircraft engines.
