The invention discloses a multi-point multi-stage regulation spoiler wedge. The multi-point multi-stage regulation spoiler wedge comprises a wind shielding substrate and a wind field regulation unit.Two rows of wind field adjusting assemblies are arranged on the same side surface of the wind shielding substrate; each wind field adjusting assembly comprises a plurality of wind field adjusting units; the wind field adjusting units are vertically distributed, and each wind field adjusting unit comprises a spoiler and a motor assembly; the motor assemblies are arranged on a side surface of the wind shielding substrate, and each spoiler is arranged on an output shaft of the corresponding motor assembly; and each spoiler is also provided with a telescopic spoiler. According to the wind tunnel test spoiler wedge device, a plurality of spoilers are arranged on a traditional wind shielding substrate (wedge) and a telescopic plate is arranged on each spoiler body, the telescopic plates can be finely adjusted on the basis of adjusting the wind field according to the position, the posture and the number of the spoilers, and thus, the multi-point multi-stage regulation spoiler wedge has the advantages of convenience and rapidness.
Description
technical field [0001] The invention relates to a wind tunnel turbulent wedge, in particular to a multi-point and multi-stage adjustable turbulent wedge. Background technique [0002] Wind tunnel experiments are an integral part of flight development. It not only plays an important role in the research and development of aviation and aerospace engineering, but also is indispensable in the fields of transportation, housing construction, and wind energy utilization with the development of industrial aerodynamics. In the wind tunnel test, the flow state of the wind is easy to control. The model or object is fixed in the wind tunnel for repeated blowing, and the experimental data can be obtained through the measurement and control instruments and equipment. The wedge and rough elements are widely used in the simulation of the atmospheric boundary layer in wind tunnel tests. The average wind speed and turbulence profile of different landform features can be simulated through the...
