Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0036] Aiming at the guiding and collecting device of the low-speed flutter wind tunnel test protection system in the prior art, the cable will be stuck in the gap between the pulley and the pulley support by the wind in the wind tunnel, which will cause the wind tunnel test to fail To solve the problem, this application provides a new type of guiding and gathering device.

[0037] Different from the design scheme in the prior art that uses two pulleys mounted on the pulley support for the guide wire collection device, the guide wire collection device in this application changes the design of the two pulleys and the pulley support in the wind tunnel. It is a bell-shaped single part, so as to achieve simple, ...

Abstract

The invention provides a guide line concentration device applied to a low-speed flutter wind tunnel test protection system. The device comprises a guide line concentrator disposed in a wind tunnel wall preformed hole, wherein the guide line concentrator is provided with a line conduit passing through the wind tunnel wall preformed hole, one end of the line conduit extends to form a horn mouth, the horn mouth rotates around the axis of the line conduit, an outer surface of the wire conduit is provided with an external thread; a through hole is formed in the middle of the locking guide device, the locking guide device is provided with internal threads matched with the external threads of the wire conduit, the side wall of the locking guide device is provided with a plurality of wire through holes which extend in the radial direction and are communicated with the through hole in the middle, and the concentrator is locked and guided to the wind tunnel wall through the locking guide device. According to the guide line concentration device provided by the invention, the cable in the wind tunnel cannot be blocked at the steering and gathering positions, a curved surface of the horn mouth of the guide line concentration device is smooth, the cable cannot be worn, a curved surface at the horn mouth is large in radius, the cable is not easy to roll, and the cable can be taken up and paid off more smoothly.

Description

technical field [0001] The application belongs to the technical field of wind tunnel tests, and in particular relates to a guiding wire collection device applied to a protection system for low-speed flutter wind tunnel tests. Background technique [0002] In the existing low-speed flutter wind tunnel test protection system, the guide wire gathering device used for guiding and bundling the control cables or cables is installed on the pulley support with two pulleys, and the cables pass through the pulleys It is realized by entering the hole that the pulley support communicates with the outside of the hole. [0003] However, when the wind tunnel test is carried out, the control cables or cables will be blown away from the middle plane of the pulley by the wind in the wind tunnel, and will be stuck in the gap between the pulley and the pulley support, resulting in the failure of the wind tunnel test to proceed smoothly. Contents of the invention [0004] The purpose of the p...
