美国国家航空航天局最近宣布,美国将在20年内登上火星。近来美国一些工程师正在考虑把自主飞行直升机作为进行火星表面探测的空中平台。为此,美国航空航天局、美国西科斯基公司和美国直升机学会,联合举办了火星探测自主飞行直升机方案设计竞赛。这项竞赛分3个单项:直升机机体设计、推进支系统设计和飞行控制支系统设计。竞赛规定:火星应能在 The United States National Aeronautics and Space Administration recently announced that the United States will fly to Mars within 20 years. Recently, some U.S. engineers are considering using autonomous flight helicopters as an aerial platform for the exploration of the surface of Mars. To this end, NASA, Sikorsky Corporation of the United States and the Helicopter Association of the United States jointly organized a Mars exploration autonomous flight helicopter program design competition. The competition is divided into 3 single items: helicopter body design, propulsion system design and flight control system design. Competition rules: Mars should be there
