Variable-angle high-temperature heat testing device for conical housing with oblique section of high-speed aircraft

Abstract

The invention relates to a variable-angle high-temperature heat testing device for a conical housing with an oblique section of a high-speed aircraft. The variable-angle high-temperature heat testing device comprises a U-shaped copper support saddle, a conical fastening screw, an annular flat copper support, an adjustable electrode support saddle, a linking and locking shaft, the conical housing with the oblique section of the high-speed aircraft, a quartz lamp heating pipe and a water-cooling copper pipe. The device can conveniently change the angle of the infrared radiation quartz lamp heating pipe mounted on a water-cooling device during a pneumatic heat simulation test and allow the infrared radiation quartz lamp heating pipe to be fast and conveniently matched with the conical housing with the oblique section of the high-speed aircraft. Simultaneously, the quartz lamp heating pipe can be cooled through cooling water in the pneumatic heat simulation test, and an electrode of the quartz lamp heating pipe can be prevented from being burned out due to outward leakage of inert gas, which is caused by large deformation when the temperature is too high. A convenient and safe high-temperature heat environment testing means can be provided for the pneumatic heat simulation test of the conical housing with the oblique section of the high-speed aircraft.

Description

technical field [0001] The invention relates to a variable-angle high-temperature thermal test device for a conical shell with an oblique section of a high-speed aircraft. Especially when simulating the aerodynamic heating environment of high-speed aircraft tests such as missiles, it has the advantages of flexible followability to the shape angle of the oblique section conical shell at the front end of the aircraft and convenient use. Provide fast and safe thermal environment simulation test means for the development of high-speed missiles and high-speed aerospace vehicles. Background technique [0002] As the design flight speed of high-speed aircraft is greatly increased, the high-temperature thermal environment generated by aerodynamic heating becomes extremely severe. If high-speed aircraft such as missiles and spacecraft fly at a Mach number of 6, the instantaneous heat flux density on the front shell of the high-speed aircraft can exceed 1.2Mw / m 2 , Local and regiona...
