The invention discloses a variable sweepback aircraft variant structure with inner and outer telescopic wings. The variable sweepback aircraft variant structure comprises outer wings, a fuselage, a lead screw system, push rods, inner wings, push rod connecting pieces, graphite copper sleeves and upper and lower guide rails, wing accommodating grooves are formed in the two sides of the fuselage respectively and used for accommodating the outer wings and the inner wings; the inner wing is located in the outer wing and connected with the outer wing through a rotating pair, and rotating motion can be achieved. The inner and outer wings are provided with chutes with special tracks, one end of a push rod is connected with the chutes, the other end of the push rod is fixed with a sliding table of a ball screw through a connecting piece, and a motor drives the screw to rotate to realize symmetrical movement of the push rod, control of actions of the inner and outer wings and wing deformation. Through the design of the sliding grooves of the inner and outer wings, the push rods are connected with the inner and outer wings through the sliding grooves, a certain supporting effect is achieved, the length of the sliding grooves is increased, the change range of the sweepback angle can be increased, the constant-speed movement of the lead screws realizes constant-speed extension of the outer wings and constant-speed rotation of the inner wings through movement of the push rods along the sliding grooves, and the overall structural design is simple and ingenious and flexible and convenient to use.
本发明公开了一种变后掠内外伸缩翼飞行器变体结构,包括外翼、机身、丝杠系统、推杆、内翼、推杆连接件、石墨铜套和上下导轨;所述机身两侧分别加工有机翼收纳槽,用于容纳外翼与内翼;内翼位于外翼内部,通过旋转副与外翼连接,可实现旋转运动;内外翼设计特殊轨迹的滑槽,推杆一端与滑槽连接,另一端通过连接件与滚珠丝杠的滑台固定,电机驱动丝杆转动,实现推杆对称运动,控制内外翼的动作,实现机翼变形。本发明通过内外翼的滑槽的设计,推杆通过滑槽与内外翼连接,起一定支撑作用,滑槽长度增加,可增大后掠角的变化范围,丝杠的匀速运动通过推杆沿滑槽运动实现外翼匀速伸出和内翼匀速旋转,整体结构设计简单巧妙,使用灵活方便。
