为了模拟飞机飞行高度、飞行爬升率和俯冲率,研制了一套高空模拟系统。本文从真空泵系统选型、高空模拟舱设计和抽气能力仿真计算等方面,论述了高空模拟系统的设计思想和技术关键,经过设备调试和试验验证表明,该高空模拟系统模拟精确,满足试验要求。
In order to simulate the aircraft flight altitude, flight climb rate and dive rate, developed a set of high-altitude simulation system. In this paper, the design ideas and technical key points of high altitude simulation system are discussed from the selection of vacuum pump system, the design of high-altitude simulation cabin and the simulation of suction capacity. After the equipment commissioning and test verification, it shows that the simulation system is accurate and meets the test requirements .
