Design of the Wind Channel for the Test-Bed of Aerodynamic Brake

Abstract

For simulating the wind load strength effect so as to detect the opening and closing performance of the aerodynamic braking device and the reliability of its opening and closing mechanism with the wind load caused by high speed flow field, the wind load test-bed is to build. Wind channel, as the equipment to turn a high pressure flow into a relatively high speed advection, is one of its important components. This paper focuses on the design of the shape of the wind channel. By the means of flow field simulation analysis, with the indexes of the wind load size, the pressure distribution and the flow equality, the shape optimization of the wind channel is realized.
