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 filaments on the surface of an airfoil, comprising: a copper tube, the upper part of which is a hollow cylinder, and the lower part is a solid cylinder; the inside of the hollow cylinder is used for injecting adhesive ; Two wire-holding grooves are two bar-shaped grooves opened on the outer wall of the hollow cylinder, which are arranged at intervals along the axis of the hollow cylinder; one opening is arranged on the outer wall of the hollow cylinder and is located between the two wire-holding grooves The space is used to connect the bottom ends of the two wire holding grooves; the opening is used to provide the entrance for the wire to enter the two wire holding grooves, so that the two ends of the wire thread are hung in the two wire holding grooves respectively. The problem of cumbersome operation and infirmity of the existing copper pipe planting silk thread method is 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...
