Problems solved by technology

In the wind tunnel test, due to the relatively low Reynolds number of the test, there is a rather long section of laminar boundary layer on the surface of the model, which causes a large difference between the state of the boundary layer on the surface of the model and the real aircraft.
This difference complicates and irregularizes the influence of Reynolds number in wind tunnel tests

Abstract

The invention provides a transition belt cutting bearing device, which belongs to the field of transition belt production, and includes a frame body and a bearing part; an installation space with a top opening is formed in the frame, and the bearing part is arranged in the frame body. One side of the frame body is also provided with a negative pressure port for connecting a negative pressure device; the bearing part includes an adsorption net plate and a positioning assembly, and the positioning assembly includes a telescopic rod and a supporting plate; the telescopic rod One end of one end is fixed to the supporting plate, and the other end is relatively fixed to the frame, so that the supporting plate can be relatively close to or away from the top opening; the adsorption net plate for carrying the transition belt is placed on on the support plate.

Description

technical field [0001] The invention relates to the field of transition belt production, in particular to a transition belt cutting and carrying device. Background technique [0002] When a real aircraft is flying in the air, due to the high flying Reynolds number, the boundary layer on the surface of each part of the aircraft is almost all in a turbulent state. In the wind tunnel test, due to the relatively low test Reynolds number, there is a rather long section of laminar boundary layer on the surface of the model, which causes a large difference between the state of the boundary layer on the model surface and the real aircraft. This difference complicates and irregularizes the influence of Reynolds number in wind tunnel tests. If the method of artificially fixing the transition of the boundary layer is adopted during the model test, so that the boundary layer on the surface of the model is similar to that of an airplane, the correction of the influence of Reynolds numbe...
