摘要
飞艇作为飞行器的一种,其工作原理与飞机、热气球等传统的飞行工具不同。飞艇上升的动力主要依靠气囊中的升浮气体来产生。所以,如何控制气囊中气体的压力对飞艇来说非常重要。压力控制过程涉及飞艇的气囊安全控制、升降速度控制等,还与飞艇的动力系统以及外部大气环境和气象条件密切相关。因此要让飞艇的压力控制做到既安全又平稳并不是一件容易的事情。本文将以飞艇的数学模型、标准大气模型和传热学基本原理为基础,探讨如何实现飞艇的气囊压力控制。
As a kind of aircraft, airship works differently from traditional ones such as airplane and balloon. The buoyancy of airship comes from lifting gas which is infused in the ballonet. Thus, it is very important as how to control the air pressure of the ballonet which is close related with outer atmosphere and climate condition, with safety control, blastoff and landing control. It＇s not an easy task not only to realize safety control while ensuring the stability. Our article will discuss how to control the air pressure of ballonet baaed on the mathematic model of airship, standard atmosphere model and Heat Transfer Theory.
