Supersonic flow calibration large-stroke single-point displacement measurement device for wind tunnel and wiring method

The invention discloses a large-stroke single-point displacement measuring device for wind tunnel supersonic flow calibration and a wiring method, and relates to the technical field of wind tunnel supersonic flow field calibration. The large-stroke single-point displacement measuring device is characterized by comprising a wind tunnel wall plate, a tail support, a main support, an executing mechanism, a connecting section, a probe switching section and a pressure measuring part, wherein the executing mechanism is a servo electric cylinder, the pressure measuring part comprises a total pressureprobe and a static pressure probe, the total pressure probe and the static pressure probe are connected with a measuring pipeline, the measuring pipeline is fixedly wound with a piston rod of the servo electric cylinder, and the measuring pipeline is connected with a balance weight located outside the wind tunnel. According to the single-point moving measurement device, the stroke of the executing mechanism is increased,
