Abstract

The invention relates to the technical field of arc wind tunnel test, in particular to a thermal response arc wind tunnel test device and method of a heat prevention and isolation material. The thermal response arc wind tunnel test device and method of the heat prevention and isolation material comprises a wind tunnel, a rotation connection piece, a water-cooling tool and a rotation driving mechanism, wherein a power output shaft of the rotation driving mechanism is connected with the rotation connection piece, the water-cooling tool is arranged on the rotation connection piece, and the water-cooling tool is corresponding to an exit of the wind tunnel. According to the thermal response arc wind tunnel test device and method of the heat prevention and isolation material, provided by the invention, an included angle between a measurement surface of a flat plate test module and a lower surface of an inner side wall of the exit of the wind tunnel can be changed, the purpose of continuouslychanging thermal flow loaded onto the measurement surface of the flat plate test model is achieved, refined and continuous operation of thermal response of the heat prevention and isolation materialunder a long-term condition is further achieved, the trueness of thermal response of the heat prevention and isolation material in arc wind tunnel test is greatly improved, and an effective support isprovided for a heat prevention and isolation design of an aircraft under the long-term flight condition.

Description

Technical field [0001] The invention relates to the technical field of arc wind tunnel testing, in particular to an arc wind tunnel testing device and method for thermal response of anti-insulation materials. Background technique [0002] In the current arc wind tunnel test, the basic design has a limited number of steps, and the design state covers the changing state of the heat flow of the aircraft along the flight profile, and the heat flow cannot be loaded along the flight profile. Although the widely used arc wind tunnel thermal response method can meet the requirements of aircraft design, as aircraft design pursues faster, higher, and farther goals, the requirements for thermal insulation design are more accurate, and the design margin for thermal insulation It is getting smaller and smaller, so it is imperative to accurately assess the anti-heat insulation design through the arc wind tunnel test. [0003] The thermal response of anti-insulation material is a process that co...
