随着时代的发展,科学技术的进步已经逐渐改变了人们的出行方式,相较于传统的铁路和水路交通,乘坐飞机出行能够在更短的时间内到达目的地,改变了传统的出行方式。目前,我国已经成为民用航空旅客运载量增长最快的区域之一,有数据表明,我国每年的航空运载量的递增速率在10%以上。因此,在这样的情况下,现代飞机的安全性已经成为了人们关注的焦点,对于大型飞机的环境控制系统的要求也是在不断提升。本文结合航空发动机的发展,在人们对于污染环境和系统安全寿命周期的关注的基础上,介绍我国大型飞机环境控制系统的关键技术,指出民用大型客机中环控系统关键技术的内涵。
With the development of the times, advances in science and technology have gradually changed people’s way of traveling. Compared to the traditional railway and waterway transportation, traveling by plane can reach its destination in a shorter time and change the traditional mode of travel. At present, China has become one of the fastest-growing passenger transport areas for civil airlines. Data show that the annual growth rate of air transport in China is above 10%. Therefore, under such circumstances, the safety of modern aircraft has become the focus of attention, and the requirements for environmental control systems of large aircraft are also constantly increasing. In this paper, based on the development of aeroengine, based on the people’s attention to the polluted environment and the system safety life cycle, this paper introduces the key technologies of the large aircraft environmental control system in our country, and points out the connotation of the key technology of the environmental control system in the civil large passenger aircraft.
