Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the present invention provides a planting device for planting fluorescent microfilaments on the airfoil surface. In some embodiments, it includes: a copper tube, two wire clamping slots 2 and an opening 7 . Wherein, the copper tube is divided into upper and lower parts, the upper part is a hollow cylinder 1, and the lower part is a solid cylinder 4, and the inside of the hollow cylinder 1 is used for injecting the adhesive for fixing the wire and the copper tube. The outer wall of the hollow cylinder 1 is provided with two wire-holding grooves 2, the direction of the two wire-holding grooves 2 is the same as the axial direction of the hollow cylinder 1, the two wire-holding grooves 2 are arranged at intervals, and the size of the wire-holding grooves 2 is different. The limit is usually selected according to...

Abstract

The invention discloses a planting device for planting fluorescent microfilaments on the surface of an airfoil profile, which comprises a copper pipe, the upper part of the copper pipe being a hollowcylinder, and the lower part of the copper pipe being a solid cylinder; and an adhesive being injected into the hollow column body; two wire clamping grooves, arranged on two strip-shaped grooves formed in the outer wall of the hollow column body and being formed in the axis direction of the hollow column body at intervals; an opening, formed in the outer wall of the hollow column body, positionedbetween the two wire clamping grooves and used for communicating the bottom ends of the two wire clamping grooves; an opening, used for allowing the silk thread to enter the inlets of the two threadclamping grooves, so that the two ends of the silk thread are hung in the two thread clamping grooves respectively. The problems that an existing copper pipe silk thread planting method is complex inoperation and not firm are solved.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel tests, and in particular relates to a planting device for planting fluorescent filaments on the surface of an airfoil. Background technique [0002] Fluorescent microfilament flow display technology is widely used in various wind tunnels and field tests due to its simple operation, wide application range and small impact on the flow field. This technology is a newly developed method of observing the surface flow field of the test model on the basis of the conventional silk flow display technology. Synthetic fibers containing fluorescent substances are used to make fluorescent microfilaments, and then fixed on the surface of the test model. The diameter of the wire made of this fiber is extremely small, which can ensure the accuracy and authenticity of the flow field near the model to a large extent, and greatly reduce the influence on the surface flow field of the test model. It is very diffi...
