Embodiment 1
[0067] In this embodiment, the optical fiber aerodynamic force measuring balance structure adopts a commonly used rod-type three-component aerodynamic force measuring balance structure. Its shape is cylindrical, including the model connection end 1, the axial force element 3, the normal force and the pitch Moment combination elements 2 and 4, support rod 5 and model support connection end 6, model connection end 1 is processed into a 1:5 taper to connect to the test model, model support connection end 6 is processed into a cylindrical surface, and is connected to the model support. Axial force element 3, normal force and pitching moment combination elements 2 and 4 are arranged between the ends, which are placed inside the test model to measure the aerodynamic force / torque of the model. The back end of the measuring element is a support rod, which is a straight cylindrical section. In order to meet the rigidity requirements, a conical section is designed at the connection with t...
