本文介绍一种定容积式的高度模拟器,它突出的优点是气压能在一个很大的压力范围内相对快速和准确的变化。应用这一设备,在地面就可精确的模拟一架飞机在实际飞行中所遇到的气压。文中对高度模拟器的工作原理,部件的构造,主要技术指标以及为实现这些要求而采取的措施作了详细说明。 This paper presents a constant-volume height simulator that highlights the advantage that the pressure can vary relatively quickly and accurately over a wide range of pressures. With this device, the ground can accurately simulate the air pressure encountered by an aircraft in actual flight. In this paper, the working principle of height simulator, the construction of components, the main technical indicators and the measures taken to achieve these requirements are described in detail.
