牛年伊始,多家新闻媒介报道了一条振奋人心的消息:我国第一代实用型地效飞行器今年将问世并交付使用。什么是地效飞机地效是地面效应的简称。当飞机在地面附近飞行时,因地面的存在就会影响围绕飞机的空气流动状况,从而使飞机气动力的特性发生改变,这种现象称为地面效应。飞机接近地面快要着陆时,翼下面有一股“推力”阻止飞机接地,这是由于
At the beginning of the Year of the Ox, a number of news media reported an exciting news: China’s first generation of ground-effect aircraft will come out this year and be delivered to use. What is the efficiency of ground-effect aircraft is short for ground effect. When the aircraft is flying near the ground, the presence of the ground will affect the air flow around the aircraft, thus changing the characteristics of the aerodynamics of the aircraft. This phenomenon is called ground effect. When the aircraft is nearing the ground, there is a “thrust” under the wing to stop the grounding of the aircraft. This is due to
