High-temperature radiation temperature enhancement device of quartz lamp used for guided missile thermal test

Abstract

The invention relates to a high-temperature radiation temperature enhancement device of a quartz lamp used for a guided missile thermal test. The high-temperature radiation temperature enhancement device comprises an interlayer water-cooled quartz lamp heating array, a water-cooled type cooper electrode base, a water flow channel of a lamp wall, a tungsten thermal fuse, a quartz lamp electrode, cooling water, a through water-cooled channel and a metal connecting pipe. A wall surface of the quartz lamp used for heating is designed into an interlayer form, part of the heat quantity on the surface of the quartz lamp can be removed by the cooling water flowing through the water flow channel of an interlayer lamp wall, so that the surface temperature of quartz glass is dropped to below softening temperature 1600 DEG C, an infrared light generated by the tungsten thermal fuse of the quartz lamp can penetrate through a wall surface of a heater of a transparent interlayer water-cooled quartz lamp and the transparent cooling water to radiate outwards. In the high-temperature radiation temperature enhancement device, a radiating capacity of the quartz lamp heating array exceeds the primary use limit temperature 1200 DEG C, and the maximum radiation temperature is increased to 1450 DEG C. Therefore, an effective high-temperature pneumatic thermal test analog method is provided for researching a hypersonic missile with faster flying speed, and the high-temperature radiation temperature enhancement device has an important application value in military engineering.

Description

technical field [0001] The invention relates to a high-temperature radiation temperature enhancing device for a quartz lamp heater used in a missile heat test. Especially when simulating the aerodynamic heating environment of the missile hypersonic flight test, it can increase the high temperature radiation temperature of the quartz lamp from a maximum of 1200°C to 1450°C. Provide effective high-temperature test means for the development of faster-flying hypersonic missiles and high-speed aerospace vehicles. Background technique [0002] Due to the needs of defense penetration, anti-missile, high-altitude and high-speed reconnaissance, missiles and other aircraft are flying faster and faster. The flight Mach number of air defense missiles and air-to-air missiles has exceeded 6 Mach numbers. The stagnation point temperature will exceed 1200°C, and there will even be a local high temperature zone reaching 1450°C in the front end of the radome cone at the front end of the miss...

Problems solved by technology

Therefore, when the surface temperature of the test piece 50-100mm away from the heater reaches 1200°C, the surface temperature of the heater used as the heat source will be close to the softening temperature of quartz glass at 1600°C, causing the vacuum seal of the quartz heater to leak, which in turn causes Tungsten filament burnt by high temperature oxidation
