Problems solved by technology

The existing atmospheric parameter simulator is mainly based on the air pressure control system of pressure servo valve / proportional valve. The advantage of this air pressure control system is that the device structure is relatively simple and has good control accuracy; It is more difficult, the cost is high, and it is difficult to achieve high pressure control, and the response speed is slow

Abstract

The invention relates to the technical field of air pressure test and simulation, in particular to an atmospheric parameter simulator. The invention aims to solve the problems of a pressure control mode based on a proportional valve, such as low response speed, high processing difficulty and the like. In order to fulfill the aim, the atmospheric parameter simulator comprises a main control module, a liquid crystal display module, a keyboard control module, a static pressure and total pressure control module and an air channel module, wherein the main control module is used for performing overriding control on the atmospheric parameter simulator; the liquid crystal display module is used for displaying system parameters and output results; the keyboard control module is used for inputting an operating instruction into a system through a keyboard so as to perform control; the static pressure and total pressure control module is used for controlling and measuring atmospheric parameters of a static pressure channel and a total pressure channel; and the air channel module is used for actually controlling and measuring the atmospheric parameters according to the instruction of the static pressure and total pressure control module. The atmospheric parameter simulator has the advantages of simple structure, low cost, high response speed and the like.

Description

technical field [0001] The invention relates to the technical field of air pressure testing and simulation, in particular to an atmospheric parameter simulator. Background technique [0002] The atmospheric parameter simulator can provide simulation of atmospheric parameters such as static pressure, total pressure, Mach number, airspeed, etc. for aircraft in the aerospace and aviation fields. Especially in the aerospace field, the requirements for atmospheric parameter simulators are higher, which requires high precision. Air pressure control, faster response speed. The existing atmospheric parameter simulator is mainly based on the air pressure control system of the pressure servo valve / proportional valve. The advantage of the air pressure control system is that the device structure is relatively simple and has good control accuracy; but the corresponding disadvantage is the processing of the pressure servo valve. It is more difficult, the cost is high, and it is difficult...
