Supersonic high-temperature three-dimensional flow field measuring device

The invention provides a supersonic speed high-temperature three-dimensional flow field measuring device. The measuring device comprises a sensing mechanism used for measuring the characteristics of a flow field and a displacement mechanism used for adjusting the position of the sensing mechanism in the flow field. The sensing mechanism comprises a rear supporting plate and a front flow guide plate used for conducting flow guide on a flow field, a cavity is formed between the rear supporting plate and the front flow guide plate, a plurality of probes are installed in the cavity and comprise a temperature sensing probe, a pressure sensing probe and a three-dimensional flow field measuring probe, and the temperature sensing probe, the pressure sensing probe and the three-dimensional flow field measuring probe are arranged in the cavity. The rear supporting plate and the front flow guide plate are connected with the displacement mechanism through a connecting plate. According to the invention, a reloading positi
