摘要： It is an object of the present invention to solve the problem of a drop in precision in conventional systems using a square pyramid type five-hole probe due to the drop in atmospheric pressure in high altitude ranges, and to provide a wide velocity range flight velocity vector measurement system that can prevent a drop in measurement precision. Furthermore, it is also an object of the present invention to provide a method for eliminating the effects of detection fluctuations caused by adhering water droplets, ice particles or dust in a wide velocity range flight velocity vector measurement system. The flight velocity vector measurement probe of the present invention comprises means in which a static pressure hole is formed in the tube wall surface of the probe, so that a static pressure value is obtained from the pressure detected by this static pressure hole, the Mach number M is calculated on the basis of an equation approximated by a fourth-order polynomial of the static pressure/total pressure signal and the angle of attack, and in cases where an abnormal detection value is detected, this is replaced by the preceding detection value.

摘要翻译：本发明的一个目的是解决由于在高海拔范围内的大气压力下降而使用方形棱锥型五孔探针的常规系统的精度下降的问题，并且提供宽的速度范围飞行速度矢量测量系统，可以防止测量精度下降。此外，本发明的另一个目的是提供一种消除在宽速度范围飞行速度矢量测量系统中粘附水滴，冰粒或灰尘引起的检测波动的影响的方法。本发明的飞行速度矢量测量探头包括在探针的管壁表面中形成静压孔的装置，从而由该静压孔检测到的压力获得静压值，马赫数基于由静压/总压力信号的四次多项式近似的方程式计算出M，并且在检测到异常检测值的情况下，将其替换为前一检测值。
