Temperature control wind tunnel device based on quartz lamp heating and test method thereof

Abstract

The invention relates to a temperature control wind tunnel device based on quartz lamp heating and a test method thereof. The device comprises a heating device, a water cooling device, an air coolingdevice and a temperature control box. The heating device includes a quartz glass frame, two quartz glass covers, and a condensation housing that are arranged successively from inside to outside. Mounting frames are arranged at the two ends of the quartz glass frame. All parts are fixed by support plates at two ends. A plurality of quartz lamps form a heating array arranged between the two quartz glass covers; and the two ends of the quartz lamps are fixedly connected with the quartz glass covers. Electrodes at the two ends of the quartz lamps are connected with a water cooling pipe and an electrode coil respectively. The water cooling pipe is connected to the water cooling device through a water-cooled pipe joint and the water cooling pipe. The electrode coil is connected with the temperature control box through a temperature control line interface and a temperature control line; and a temperature sensor is connected to the temperature control box through the temperature control line joint and the temperature control line. The water cooling pipe is arranged at the outer side of the condensation housing; the outlet is communicated with sealed space formed by the two quartz glass covers and a test segment support plate; and the inlet is connected with the air cooling device by an air cooling conveying pipe.

Description

technical field [0001] The invention relates to a temperature-controlled wind tunnel device based on quartz lamp heating, which is especially suitable for ground aerothermal simulation experiments of hypersonic aircraft. Compared with traditional total temperature-controlled wind tunnels and thermal wind tunnels, it has a good flow field It has good simulation effect and good thermal environment simulation effect, and belongs to the high-temperature thermal flow field simulation device in the field of aerospace. Background technique [0002] In the past half century, countries around the world have paid more and more attention to hypersonic vehicles, and have invested more and more manpower and material resources in the development of hypersonic vehicles. In the past ten years, my country has also vigorously developed hypersonic aircraft. Typical hypersonic aircraft such as the X-51 Blackbird reconnaissance aircraft and the X-47B unmanned aerial vehicle fly at a speed above...

AI Technical Summary

Problems solved by technology

Therefore, the size of the high-pressure gas cylinder limits the working time to a certain extent

[0006] Compared with the hot wind tunnel, the total temperature control wind tunnel can achieve very good flow field characteristics and can also achieve a longer working time, but it cannot make the airflow reach the temperature of hypersonic flight
