Engine hanger for tilting ducted aircraft
Engine hanger for tilting ducted aircraft
The invention discloses an engine hanger for a tilting ducted aircraft, which is used for fixedly mounting an electric propulsion engine on the upper wing surfaces of an integral flaperon and a full-motion horizontal tail of the tilting ducted aircraft through the engine hanger. The electric propulsion engine can be driven to tilt between horizontal propulsion and vertical propulsion along with the deflection of the integral flaperon and the full-motion horizontal tail; the chordwise installation position of the engine hanging frame on the tilting movable face is determined by an intersection point A of the front edge of the engine hanging frame and the upper surface of the tilting movable face, and when the chord length of the tilting movable face is c, the chordwise position of the projection of the point A on the upper surface of the tilting movable face ranges from 0.42 c to 0.52 c. Through the optimized design of the hanging frame, structures such as the section shape of the hanging frame, the height of the supporting mechanism and the shapes of the front edge and the rear edge can be optimally designed according to the given engine duct, the wing surface efficiency and the safety of the rotor duct can be effectively improved, and the flutter characteristic is improved.
本发明公开了一种用于倾转涵道飞机的发动机挂架，用于将电推进发动机通过其固定安装在倾转涵道飞机的整体式襟副翼和全动平尾的上翼面上，并可随着所述整体式襟副翼和全动平尾的偏转而带动电推进发动机在水平推进和垂直推进之间倾转；所述发动机挂架在所述倾转活动面上的弦向安装位置由发动机挂架的前缘与所述倾转活动面的上表面的交点A所确定，当所述倾转活动面的弦长为c时，所述A点在倾转活动面的上表面投影的弦向位置在0.42～0.52c之间。本发明通过优化的挂架设计，可以根据给定的发动机涵道，优化设计包括挂架的剖面形状，支撑机构的高度、前后缘形状等结构，能够有效提升翼面效率和旋翼涵道的安全性，改善颤振特性。
