西科斯基公司网站2014年10月2日发布了S-97“侵袭者”高速直升机原型机。该公司作为世界级的顶尖直升机制造商,发布这款全新旋翼机意味着直升机家族新一轮的更新换代已经开始了,外界对S-97的评价是具备“颠覆性”的气动设计,采用了与众不同的共轴反转刚性旋翼作为主要的升力来源,尾部安装了螺旋桨推进装置,机身修长,这样的气动增强了直升机的机动性和灵活性。西科斯基公司认为S-97项目将作为未来高速直升机的雏形,也引领着旋翼机领域的发展。尤其是刚性旋翼加尾螺旋桨推进器的气动布局,承载了西科斯基对21世
Sikorsky’s website released the S-97 “Invader ” high-speed helicopter prototype on October 2, 2014. The company as a world-class top helicopter manufacturer, released this new rotorcraft means that the helicopter family a new round of replacement has already begun, the outside world on the S-97 evaluation is with “subversive” aerodynamic design, A distinctive coaxial inversion rigid rotor is used as the main source of lift. Propeller propulsion units are fitted to the rear and the fuselage is slender. This aerodynamic enhances the mobility and agility of the helicopter. Sikorsky believes the S-97 project will be the prototype of the future high-speed helicopter and will lead the development of the rotorcraft. In particular, the aerodynamic layout of the rigid rotor plus tail propeller propulsion, carrying Sikorsky on the 21st
