A vertical fixed wing folding structure comprises a wing folding structure and a locking mechanism, one side and the other side of the wing folding structure are fixed to a fixed wing spar and a folding wing spar of a vertical take-off and landing machine respectively, and the wing folding structure comprises hinges connected to the upper surfaces of the fixed wing spar and the folding wing spar. A screw retracting and releasing module is arranged between the fixed wing spar and the folding wing spar and is driven by a driving motor embedded in the fixed wing spar, the locking mechanism comprises a positioning plate fixedly arranged in the folding wing spar, a positioning hole is formed in the end part of the positioning plate, a steering engine and a ball head pull rod are arranged in the fixed wing spar, and the positioning hole is formed in the end part of the positioning plate. A limiting inserting hole is formed in the end of the ball head pull rod, the limiting pin is slidably connected into the limiting inserting hole in a sleeved mode, one end of the limiting pin is connected with the steering engine through a pull rope, and the limiting pin is inserted into the positioning hole. The wingspan of the aircraft in the hangar can be reduced to 60% of the wingspan in a cruise operation state, so that the size of the hangar is remarkably reduced, and the building cost of the hangar is saved.
一种垂起固定翼机翼折叠结构,包括机翼折叠结构和锁紧机构,机翼折叠结构一侧和另一侧分别固定在垂直起降机的固定翼翼梁和折叠翼翼梁上,机翼折叠结构包括连接在固定翼翼梁和折叠翼翼梁上表面的合页,在固定翼翼梁和折叠翼翼梁之间设置螺杆收放模块,螺杆收放模块通过嵌设在固定翼翼梁内的驱动电机驱动,锁紧机构包括固设在折叠翼翼梁内的定位板,定位板端部设置有定位孔,在固定翼翼梁内设置有舵机和球头拉杆,球头拉杆的端部设置有限位插孔,限位销滑动套接在限位插孔内,限位销一端通过拉绳与舵机连接,限位销插接在定位孔内。本发明能够将飞行器在机库中的翼展降低为巡航作业状态下的60%,进而显著降低机库尺寸,节省机库建造成本。
