Novel heat insulation patch applied to supersonic missile

Abstract

The invention discloses a novel double-layer heat insulation patch applied to a supersonic missile. The patch is made of non-metal and metal materials, an external environment heat source is efficiently blocked through low heat conductivity of the non-metal materials, the internal environment temperature is reduced through the high density characteristic of the metal materials, and environment temperature protection is provided for missile structures and instrument equipment in cabins. The novel heat insulation patch is additionally provided with the metal layer, the heat insulation effect of the novel heat insulation patch is better than that of a traditional heat insulation material, and the novel heat insulation patch has good mechanical properties and can bear a certain mechanical load environment. The novel heat insulation patch is wide in application range and can insulate heat inside and outside the missile. The patch manufacturing process is simple, and special processing equipment is not needed.

Description

technical field [0001] The invention provides a heat insulation scheme applied to supersonic missiles, which belongs to the field of anti-heat insulation design of aircraft structures. Background technique [0002] Supersonic missiles fly at low altitude and high speed, and the environmental dynamic pressure is very large. In addition to flying for a long time, the aerodynamic heating environment faced by the missile structure is harsh. Studies have shown that when the missile flight Mach number exceeds 2.5, the body wall temperature of the metal material will exceed 400°C. The high wall temperature of the missile will seriously weaken the strength of the load-bearing structure of the missile body and adversely affect the normal operation of the equipment inside the bomb bay, resulting in a decline in the flight performance and flight quality of the missile, and even endangering flight safety. Therefore, the anti-heat insulation design is an indispensable part in the design...

Problems solved by technology

These materials can effectively block the transfer of heat, but their low density can easily cause the temperature of the material itself to be too high, resulting in that the heat insulation effect is not obvious when the material is thin
