Threefold JOINT TEST aerodynamic model

摘要

The invention relates to the field of experimental aerodynamics of aircraft. Threefold hinge for wind tunnel models test comprises rack rocker and the housing with bearings and sensors angles rack mounted above the upper surface of the wind model, the body is made of two separate parts mounted on both sides of the rocker and the angle sensor configured to remote transmission via radio signal . The technical result of the implementation of the utility model is to improve the accuracy of the test model at high angles of attack, increasing the range of the studied angles of attack and slip model, the growth of the reliability of the hinge, reducing interference angle measurement signals.
