摘要
本文介绍了可用于测量风洞中旋转模型表面压力分布的集成测试系统。本系统包括两部分:装在模型内部的记录黑匣子和与控制计算机相连接的地面控制系统。地面控制系统与记录黑匣子采用无线指令传输方式,在模型高速旋转时可以实现实时控制压力数据的采集。由于采用了新开发的存储测试及微封装技术,此系统具有体积小、容量大、通道多等优点。可广泛用于风洞模型压力参数测试中。
The paper introduced a spinning model surface pressure measurement sy which used in the wind tunnel. By using varies new developed data acquisition and stor measuring technologies, this system has only two parts: a recorder box in the spinning model an real-time control box connected to the control computer on the ground. A wireless contn commands transfer model included in the system.
