摘　　要：针对4.2m直径旋翼模型试验桨叶表面压力测量中的问题,使用桨叶表面布置毛细管的方式进行测压。利用CFD技术完成表面压力的预估,指导毛细紫铜管布置,完成桨叶结构设计、测试系统设计等内容,并且通过一个标定试验对不同长度、不同内径毛细管的测压性能进行研究。这种测量方法具有成本低、可靠性高、测试精度高等优点,可以应用于后期的试验。According to the 4. 2 meters diameter rotor mode test of blade surface pressure measurement,used a capillary tube on the surface of the blade completed blade surface pressure measurement. Firstly,using CFD technique arranged on blade surface pressure prediction,guide capillary arrangement,completed blade structure design,equipment layout,pressure test system design,strength analysis etc.. And through a calibration test on the different length and diameter of the capillary pressure measurement the capillary pressure measurement,obtained the performance of the capiliary pressure measurement. The measuring method had the advantages of low cost,high reliability and high test precision,which can be used in the later period experiment.
