Telescopic wind duct for wind tunnel

Abstract

The invention discloses a telescopic wind duct for a wind tunnel. The wind duct at least comprises two big wind ducts and one small wind duct; the two big wind ducts are movably connected by the small wind duct; the telescopic wind duct is specifically characterized in that two end parts of the small wind duct are respectively stretched into the big wind ducts; the external wall of the small wind duct is matched with the internal walls of the big small ducts in a sliding manner; the end parts of the big wind ducts are provided with rubber rings; chutes are arranged at intervals on the external wall of the small wind duct; and rollers are arranged at the bottoms of the big wind ducts. According to the telescopic wind duct for the wind tunnel, the heavy overall wind tunnel is divided into a plurality of conveniently moved telescopic wind ducts, so that the length of the telescopic wind duct can be flexibly changed; moreover, the big wind ducts are provided with the rollers, so that each part can be moved conveniently; and the parts can be self-assembled according to the requirements, so that the wind tunnel is applicable to multiple experimental tasks.

Description

technical field [0001] The invention relates to equipment for aerodynamic experiments, in particular to a telescopic air cylinder used in a wind tunnel. Background technique [0002] In the 21st century, as a new period of human development, the level of science and technology has been continuously improved, and various technologies that are changing with each passing day have developed comprehensively and rapidly. As a subject closely related to human beings, aerodynamics research is of great significance to test guidance. To conduct aerodynamic research, it is necessary to use a wind tunnel platform to simulate the atmospheric environment. As a basic equipment for aerodynamic experiments, the wind tunnel provides the required flow field for aerodynamic research experiments. It is a modern science and technology. Especially the product of the rapid development of aerodynamics and fluid mechanics, the birth of the wind tunnel has enabled a large number of aerodynamic experi...

Problems solved by technology

For colleges and universities across the country, more and more scientific research projects require the use of wind tunnels, and the construction of traditional wind tunnels requires a lot of manpower and material resources

However, most scientific research projects do not have high requirements for wind tunnels, and because of the limitation of manpower and material resources, most universities hope that wind tunnels can complete multiple experimental tasks

[0004] Nowadays, when small wind tunnels face different experimental tasks, the length of each part of the wind tunnel is usually fixed. In different experimental tasks, it is necessary to replace the wind tunnel with different lengths. The operation is neither flexible enough nor can it adapt to multiple The experimental tasks
