A test bracket for anti-erosion test of heat protection material

Abstract

The invention relates to a scouring resistance testing support for a thermal protecting material. The scouring resistance testing support for the thermal protecting material comprises two empty cavities, wherein one empty cavity is provided with a triangular section, and the other empty cavity is provided with an inverted trapezoidal section; the bottom edge of the triangle is connected to the long edge of the inverted trapezoid; a front edge is arranged on the top angle of the triangle, and the section of the triangle is sector. The scouring resistance testing support for a thermal structure,a rigid heat insulation tile and a flexible heat insulation felt is simple in structure, and easy to assemble; scouring resistance tests of the thermal structure, the rigid heat insulation tile and the flexible heat insulation felt are realized; a whole scouring resistance test is simplified, and moreover, all scouring resistance test requirements are met; the actual application value is high.

Description

technical field [0001] The invention belongs to the technical fields of aviation, aerospace and near space, and relates to a thermal structure, a scour-resistant test support for thermal protection materials such as rigid heat-insulating tiles and flexible heat-insulating blankets. Background technique [0002] Aerospace vehicles and hypersonic vehicles have high flight speeds, large aerodynamic heating effects, and a large number of system equipment inside. These system equipment basically work in a relatively low temperature environment, which requires the outer surface of the body to have a heat insulation function; at the same time, Under the action of aerodynamic load, thermal protection materials such as thermal structure, rigid thermal insulation tile and flexible thermal insulation felt may damage the surface. However, the anti-scouring experiment of the whole machine is expensive and takes a long period, which is not conducive to experimental research. Therefore, a ...

[0002] Aerospace vehicles and hypersonic vehicles have high flight speeds, large aerodynamic heating effects, and a large number of system equipment inside. These system equipment basically work in a relatively low temperature environment, which requires the outer surface of the body to have a heat insulation function; at the same time, Under the action of aerodynamic load, thermal protection materials such as thermal structure, rigid thermal insulation tile and flexible thermal insulation felt may damage the surface. However, the anti-scouring experiment of the whole machine is expensive and takes a long period, which is not conducive to experimental research. Therefore, a simplified and representative test piece is urgently needed for experimental demonstration.

[0003] Domestic aerospace vehicles and hypersonic vehicles are still in the research and development stage, and various experimental parts and supports are still immature, and there is no ready-made technology for reference
