Gobi Integrated environment wind tunnel simulation device

Abstract

The invention discloses a Gobi integrated environment wind tunnel simulation device applied to the field of environment wind tunnel simulation equipment. The Gobi integrated environment wind tunnel simulation device comprises a power segment, a snow segment and a test segment arranged in sequence; a fan is arranged in the power segment; a snow generator is arranged in the snow segment; a sand generator is arranged at an entry of the test segment; the lower wall of the test segment is provided with a rotary table that bears an experimental model; the upper wall of the test segment is provided with a rainfall device and a plurality of solar radiation lamps. Much of current environment wind tunnel experimental devices refer to fluid mechanics researches in the aircraft or aerospace field, andthere are scarcely no simulation devices for Gobi integrated environment wind tunnels. As Gobi is a terrain of certain converge in the territory of China, simulation researches on Gobi integrated environments are of significant practical guidance on running and flight of automobiles and unmanned aerial vehicles in Gobi. The Gobi integrated environment wind tunnel simulation device can function tosimulate Gobi experiencing sandstorm, blizzard, windstorm and high-solar-irradiation environments.

Description

technical field [0001] The invention belongs to the field of environmental wind tunnel simulation devices, and in particular relates to a Gobi comprehensive environmental wind tunnel simulation device. Background technique [0002] Gobi mainly refers to the desert area where the ground is almost covered by coarse sand and gravel, and the plants are scarce. China's Gobi is widely distributed in the vast desert and semi-desert flat land to the northwest of the line of Undur Temple-Bailing Temple-Otog Banner-Yanchi, with a total area of ​​about 455,000 square kilometers. The surface of the Gobi is composed of loess and slightly larger sand and gravel. When the wind blows, most of the dust is blown up. When the wind is strong, there will be flying sand and rocks. In addition to the windy and sandy environment, the Gobi also has high solar radiation, as well as the environmental conditions of rainfall and snowfall. [0003] The current wind tunnel experimental devices for the e...
