摘要
针对风洞试验中现有的有线测压管测压法的不足,设计并制作了一个将32 b ARM 7嵌入式系统以及无线数据传输技术与风洞试验相结合的无线测压系统,用于低速风洞试验中翼型表面压力分布的测量.将测压设备安装于模型内部,提高了系统的测量精度,并且能够实现对运动模型表面压力分布的测量.使用系统进行风洞试验的结果表明,系统成功地实现了模型表面压力分布的无线测量.
This paper introduces a wireless pressure measuring system for measuring the surface pressure of the aerofoil in the low-speed wind tunnel. Wireless data transmission technology and the 32 bit ARM7 embedded system are used. Measuring precision is increased by fixing the system inside the model. And the system can also measure the surface pressure of the moving model. The experimental results demonstrate that the system can successfully finish the wireless pressure measuring task.
