壁面静压是开展流体力学试验所需要获取的基本参数。为了提高壁面静压测量的准确性,通常需要对壁面静压进行整体联校。但是对于一些复杂的型面,如存在较大表面曲率的弯曲壁面等,整体联校实施难度大,且联校结果准确性差。本文围绕如何降低复杂型面上壁面静压整体联校难度,设计了专用的联校接头,改进了整体联校的方法,成功地应用于进气道/发动机相容性试飞中,取得了良好的效果。
Wall static pressure hydrostatic test is to obtain the basic parameters needed. In order to improve the accuracy of the wall static pressure measurement, it is usually necessary to conduct integral calibration of the wall static pressure. However, for some complicated profiles, such as curved walls with larger surface curvature, the overall joint school is difficult to implement and the accuracy of the joint school results is poor. This paper focuses on how to reduce the difficulty of the overall hydrostatic pressure on the complex surface, designed a special joint school joint, improved the overall method of joint school, successfully used in intake / engine compatibility test flight, and achieved good Effect.
