Abstract

The invention provides a testing device used for measuring the heatproof performance of an aircraft fuel tank and an application method thereof. The testing device comprises a support module, a fuel tank fixing module, a heater module used for heating a fuel tank and a temperature used for measuring the temperature of the tank body of the fuel tank. The support module comprises support columns and crossbeam units. The number of the support columns is at least three. The crossbeam units are arranged between two adjacent support columns and are in detachable connection with the support columns. The fuel tank is in detachable connection with the crossbeam units through the fuel tank fixing module and is arranged in the support module. The invention provides the testing device used for measuring the heatproof performance of the aircraft fuel tank and the application method thereof, there is no need to arrange a plurality of different testing devices, and the cost is lowered; in addition, the installation position of the fuel tank can be adjusted, so that the testing device can met different test requirements and is applicable to the fuel tanks different in size, and the universality is higher.

Description

technical field [0001] The invention relates to the field of testing of aircraft components, in particular to a test device for measuring the temperature resistance performance of an aircraft fuel tank and a method for using the same. Background technique [0002] Hypersonic aircraft generally refers to aircraft, missiles, artillery shells and other winged or wingless aircraft that fly faster than 5 times the speed of sound. One of the difficulties encountered in the development of hypersonic vehicles is the problem of aerodynamic heating, the so-called thermal barrier. It is mainly due to the effect of shock wave and viscosity when the aircraft is flying, the temperature of the surrounding air rises sharply, forming a severe aerodynamic heating environment, which makes the general aircraft structure unbearable. In order to overcome the thermal barrier, researchers first carefully design the flight trajectory and aerodynamic shape of the aircraft so that the aerodynamic hea...
