摘要
测压的典型安装位置为机头、翼尖、垂尾,文中简述了三种安装位置对应的高度误差。针对上述静压测量误差,提出了几种误差补偿方法,包括安装位置互为补偿,及静压管气动补偿。通过对两种方法进行风洞试验,验证了在马赫数1.15以内,位置误差被补偿到不足静压的0.5%。静压测量误差补偿对于在不同飞行高度间保持安全的纵向间隔具有重要意义。
The typical installation positions for pressure measurement are the nose,wing tip,and vertical tail,and the corresponding altitude errors are briefly described in the article.In view of the above-mentioned static pressure measurement errors,several error compensation methods are proposed,including compensation for the installation positions and aerodynamic compensation of the static pressure pipe.Through wind tunnel tests on the two methods,it is verified that within Mach number 1.15,the position error is compensated to less than 0.5%of the static pressure.The static pressure measurement error compensation is of great significance for maintaining safe vertical separation between different flight altitudes.
