为满足某型飞机/发动机相容性试验要求,提出了一种基于插板试验数据的半经验方法,用于模拟板的设计.在获得模拟板大致轮廓和阻力系数校验的基础上,通过模型的吹风校准试验和若干次环面基元畸变指数的调整,对比目标图谱的环面畸变强度和环面低压区大小,确定开孔的环面、孔的数量和孔的尺寸.结果表明,模拟的流场可满足某型飞机/发动机试验的要求.
In order to meet the requirements of a certain type of aircraft / engine compatibility test, a semi-empirical method based on test data of plug-in board is proposed for the design of analog board.On the basis of obtaining approximate outline of simulation board and checking the resistance coefficient, The air blow calibration test and the adjustment of some toroidal primitive distortion index were carried out to compare the torus distortion intensity of the target map and the size of the low pressure area of the torus to determine the torus, the number of holes and the hole size of the open hole.The results show that, The simulated flow field can meet the requirements of a type of aircraft / engine test.
