Problems solved by technology

[0002] During the flight of the aircraft, the pulsating pressure at a special position is unsteady. Therefore, when carrying out aerodynamic tests on the ground, it is necessary to measure the unsteady pulsating pressure on the surface of the aircraft structure. Aerodynamic tests are carried out to measure the unsteady pulsating pressure in the high temperature environment (for example: measuring the unsteady pulsating pressure in the combustion chamber of the engine), but it is difficult to obtain the unsteady pulsating pressure of the aircraft in the high temperature environment

Abstract

This application relates to the field of aerospace test technology, in particular to an unsteady-state pulsating pressure test system in a high-temperature environment, which is cooled by a circulating cooling chamber, thereby ensuring that the pulsating pressure sensor is not damaged by high temperature, and then the measured pulsating pressure y( t), and the actual pulsating pressure x(t) is obtained by modifying the transfer function H(∫).

Description

technical field [0001] The present application relates to the technical field of aerospace testing, in particular to an unsteady-state pulsating pressure testing system in a high-temperature environment. Background technique [0002] During the flight of the aircraft, the pulsating pressure at a special position is unsteady. Therefore, when carrying out aerodynamic tests on the ground, it is necessary to measure the unsteady pulsating pressure on the surface of the aircraft structure. Aerodynamic tests are carried out to measure the unsteady pulsating pressure in a high temperature environment (for example: measuring the unsteady pulsating pressure in the engine combustion chamber), but it is difficult to obtain the unsteady pulsating pressure of the aircraft in a high temperature environment. [0003] Therefore, how to obtain the unsteady pulsating pressure in a high-temperature environment is a technical problem urgently needed to be solved by those skilled in the art. C...
