Abstract
The invention provides a movable correcting device for a common hypersonic-velocity wind tunnel. The movable correcting device is used for measuring exit flow field velocity of a nozzle of the common hypersonic-velocity wind tunnel. The movable correcting device comprises a bent frame, a holder and a running gear. The bent frame comprises a bent frame arm, a bent frame seat, a vertical column and a flange. The bent frame arm is fixed on the bent frame seat. The plane where the bent frame arm exists is perpendicular to the axis of the wind tunnel. The bent frame arm is provided with a measuring pipe. The bent frame seat is connected with the vertical column through a thread and a key. The vertical column is fixed on the flange. The bent frame is fixed on the holder through the flange. With the holder, the running gear drives the bent frame to axially move along the wind tunnel, in this way, fluid velocity of sections of the exit flow field of the nozzle is measured. The movable correcting device has the advantages that the sections of the flow field can be measured at a time, structure is simple, mounting and demounting convenience is facilitated, and measuring precision is high.
