摘　　要：针对发动机进气口总温总压测量的需求,设计了一种滞止罩式总温总压光纤复合探针。首先,利用有限元法对探针结构进行气动仿真,分析了探针结构参数对测量结果的影响。在此基础上,制造了总温总压光纤复合探针,并搭建了静态测试系统测试了其工作性能。实验结果表明,总温总压光纤复合探针可以工作在150℃,0.25 MPa的温压复合环境中,在常温至150℃范围内总压传感器的最大非线性度为0.5%,常压环境下总温传感器最大非线性度为4.04%。最后,根据温度数据完成了压力参数的温度解耦,全温区压力测量误差不超过1.55%。设计的总温总压光纤复合探针直径为5 mm,有效减少了探针对流场的干扰。A stagnation cover type total temperature and pressure fiber-optic composite probe is designed for the demand of total temperature and pressure measurement at the engine inlet.Firstly,the aerodynamic simulation of the probe structure was carried out by using the finite element method,and the influence of the probe structure parameters on the measurement results was analyzed.On this basis,the total temperature and pressure fiber-optic composite probe was fabricated and its working performance was tested by building a static test system.The experimental results show that the total temperature and pressure fiber-optic composite probe can work under the temperature and pressure composite environment of 150℃and 0.25 MPa.The maximum nonlinearity of the total pressure sensor is 0.5%in the range of room temperature-150°C,and the maximum nonlinearity of the total temperature sensor is 4.04%in the ambient pressure environment.Finally,the temperature decoupling of the pressure parameters was completed,and the pressure measurement error in the full temperature range did not exceed 1.55%.The designed total temperature and pressure fiber optic composite probe diameter is 5 mm,which effectively reduces the interference of the probe to the flow field.
