In measuring high subsonic internal flows which are observed in high speed turbomachines such as transonic or supersonic compressors, authors planned to use a cylindrical probe which was supported at both ends, and got satisfactory results in the case of zero inclination angle.
Furthermore, the inclination characteristics of this probe were investigated experimentally and it was revealed that the yaw angle of flow could be easily obtained independently of both Mach number M∞ and inclination angle α. It was also revealed that the flow component normal to the axis of the probe (total pressure P0, Mach number M∞) could be obtained with a fair accuracy from the characteristics of zero inclination angle within the range of not too large inclination angles (about ±15 degrees).
