Three-hole transonic speed pressure probe

摘要: The invention discloses a three-hole transonic speed pressure probe. As pneumatic technology develops, air flow appears more and frequently, for instance, many flows in an aeroengine reach state, so these fields need to be measured analyzed during development of engine components. Conventionally, the are respectively by use total probe direction that directions can obtained. When reaches speed, probes under great resistance, blown bent easily. ultrasonic due existence shock waves, there is large loss, influences exerted on quite large. Though conventional used flow, cannot neglected, requirement strength high. novel provided measuring fields. By invention, intensity waves front weakened measurement, reduced, air-flow pressure, static Mach number deflection angle simultaneously, resistance acting effectively firmness reliability guaranteed.
