摘　　要：为满足立式风洞方向场动压场测量需求,提出一种双倒“T”型结构的方向场动压场组合测量装置方案。采用电机同步控制实现排管架的水平和垂直方向运动,排管架横截面采用NACA0020对称翼型,将原有直径12 mm的五孔探针优化为8 mm,并进行现场安装调试。检测结果表明,该装置水平和垂直方向的位移同步控制精度为0.2 mm。在立式风洞进行一期方向场动压场测量试验,结果表明:该装置性能较为先进,准确地测得了立式风洞试验段模型区内的方向场和动压场数据,能够作为今后立式风洞流场校测主力装置之一。In order to meet the requirements of the measurement of the dynamic pressure field in the vertical wind tunnel,a combined measurement device with double inverted“T”structure is proposed.The horizontal and vertical movement of the pipe rack is realized by the synchronous control of the motor.The cross section of the pipe rack adopts NACA0020 symmetrical airfoil.The original five-hole probe with a diameter of 12 mm is optimized to 8 mm,and the field installation and commissioning are carried out.The test results show that the control precision of the device in the horizontal and vertical directions is 0.2 mm.The first phase of the directional field and dynamic pressure field measurement test was carried out in the vertical wind tunnel.The results show that the performance of the device is more advanced,and the directional field and dynamic pressure field data in the model area of the vertical wind tunnel test section are accurately measured,which can be used as one of the main devices for flow field calibration in the future.
