Problems solved by technology

[0006] The purpose of the invention of the present application is to: in the process of transforming the high-speed wind tunnel to expand the range of its maximum operating Mach number, it is necessary to develop a solid block nozzle device with an extended nozzle, and the nozzle device is left by the wind tunnel. Due to the influence of the fixed space position, the new nozzle device is often unable to be installed because the nozzle is too long, or it is difficult to ensure that the profile of the new nozzle has a stable streamlined contact with the structure of other sections of the wind tunnel. To provide a profile Foldable and unfoldable wind tunnel solid block nozzle device

Embodiment 1

[0045] The schematic diagram of the aerodynamic profile of the nozzle section and other components of the high-speed wind tunnel is as follows: figure 1 shown. In this figure, the spatial position of each section of the wind tunnel has been fixed, and the position of the nozzle section corresponds to the installation position of the solid block nozzle device. The local schematic diagram of the original solid block nozzle device is as follows: figure 2 shown. The device is the original solid block nozzle device structure designed during the construction period of the high-speed wind tunnel. Design a qualified working flow field within the Mach number range. In terms of installation method, the original solid block nozzle device can directly enter the position of the nozzle section, and quickly connect with other section structures of the wind tunnel, and can also be directly disengaged from other section structures to move out of the nozzle section position.

Abstract

The invention discloses a solid block spray pipe device applied to a wind tunnel and provided with a foldable profile, and aims to solve the problem that a solid block spray pipe device with a lengthened spray pipe is required to be developed in a process of reconstructing a high-speed wind tunnel to expand the highest work Mach number range of the high-speed wind tunnel but a new spray pipe device always cannot be mounted due to the too long spray pipe under the influence of fixed space position left by the wind tunnel to the spray pipe device. The solid block spray pipe device applied to thewind tunnel and provided with the foldable profile is provided and comprises a box body, a spray pipe assembly, a frame and a power drive assembly, wherein the box body is arranged on the frame, andthe frame is arranged on the power drive assembly. On the basis of structural improvement, the new spray pipe can be mounted on a wind tunnel structure in limited space, a lengthened spray pipe profile meeting the pneumatic design requirement is formed, furthermore, the new spray pipe profile is in stable streamline contact with other section structures of the wind tunnel, and effective expansionof the highest work Mach number range of the wind tunnel is realized jointly.

Description

technical field [0001] The invention relates to the field of high-speed wind tunnel aerodynamic structures, in particular to a novel solid block nozzle device for a wind tunnel, in particular to a wind tunnel solid block nozzle device with a foldable and unfoldable profile. Based on the improvement of the structure, the invention can effectively expand the range of the highest working Mach number of the high-speed wind tunnel, and has a good application prospect. Background technique [0002] The high-speed wind tunnel is composed of many sections in terms of aerodynamic design, one of the important sections is the nozzle section, before the nozzle section is the contraction section, and after that is the test section. In high-speed wind tunnels, the structure corresponding to the nozzle section is the nozzle device, and most high-speed wind tunnels use solid block nozzle devices. [0003] The solid block nozzle device is mainly composed of nozzles and other components, and...
