空中快车工程:航空运输是本世纪出现的一种运输方法。目前,研制载客更多、航速更快、安全性能更好的特超音速“空中公共汽车”,已成为世界各国共同关心的一个重大工程项目。设计师设想中的飞机将是双体和三体的,翼展将达150米。在这种机翼中除可载客1700名外,还可装载少量货物。卫星定位系统:目前,在赤道上空,已出现同步卫星“客满”的趋势,如何来解决这种困境呢?预计在21世纪卫星系统将逐步向综合、组网、长寿命和全天候的方向发展,以便适应随时变化的要求和全球
Air Express Engineering: Air transport is a transport method of this century. At present, the development of a supersonic “sky bus” with more passengers, faster speeds and better safety performance has become a major project of common concern to all countries in the world. The aircraft the designer envisaged will be both catamaran and trisomy, with wingspan of up to 150 meters. In this wing in addition to carrying 1,700 passengers, but also can load a small amount of goods. Satellite Positioning System: At present, over the equator, there has been a trend of “fullness” of geostationary satellites. How to solve this dilemma? It is estimated that the satellite system will gradually develop in a comprehensive, networking, long-life and all-weather direction in the 21st century In order to adapt to changing requirements and global
