5. 내 용 :


There have been numerous studies conducted on the dual-mode or convertible aircraft that can takeoff and land vertically and fly like a fixed-wing aircraft in high-speed forward flight. For the dual-mode aircraft, the conversion to and from the fixed-wing mode remains the most critical phase in the entire fight spectrum. Among the aircraft concepts with low disc loadings are the tilt wing, and the x-wing. The feasibility of the tilt wing aircraft that rotates a wing with engines for flight mode changes has been confirmed through flight test programs conducted in the 1960’s in the US and Canada. However, no operational aircraft has ever been built. The x-wing aircraft with stoppable rotor wings was a subject of much interest in the 1980’s in the US, but the feasibility of the concept has not been confirmed via flight tests. This talk attempts to provide a historical account of the research on these types of aircraft, identify technical issues and discuss their potential as unmanned aerial platforms
