A single power source airfoil variable sweepback and locking mechanism comprises a power output rod, a rocker arm, a rotating shaft, a locking piece, an airfoil and a spar, the power output rod is hinged to the rocker arm, the rocker arm is sleeved on the rotating shaft, the spar is fixedly connected with a fuselage, a rotating joint of the airfoil is arranged in a clamping lug of the spar, and the rotating shaft penetrates through the airfoil and is fixedly connected with the spar; the locking piece penetrates through the rotating shaft, the rocker arm and the wing spar and then is inserted into the wing surface, the locking piece cannot rotate around the rotating shaft, and a spring is connected between the locking piece and the fuselage; an initial locking hole, a locking hole and a groove are formed in the wing surface; the locking piece is provided with a sawtooth-shaped groove used for placing the rocker arm at the initial position. The variable sweepback function of the airfoil and unlocking and locking of the airfoil at a specific angle can be achieved by means of a single power source, the variable sweepback function of the airfoil and an unlocking and locking mechanism are integrated, and the pressure of the variable sweepback system of the airfoil on an energy power system, the structural weight and the internal space of an aircraft is effectively reduced.
一种单动力源翼面变后掠及锁定机构,包括动力输出杆、摇臂、转轴、锁紧件、翼面及翼梁,其中,动力输出杆与摇臂铰接,摇臂套装在转轴上,翼梁与机身固定连接,翼面的旋转接头置于翼梁的夹耳内,转轴穿过翼面与翼梁固定连接;锁紧件穿过转轴、摇臂、翼梁后插入翼面内,锁紧件不能绕转轴发生旋转,并在锁紧件与机身之间连接有弹簧;翼面上设置有初始锁定孔、锁定孔和凹槽;锁紧件上设置有用于将摇臂置于初始位置处的锯齿形槽。本发明依靠单一的动力源能够实现翼面的变后掠功能以及翼面在特定角度下的解锁与锁定,并将翼面的变后掠功能、解锁与锁定机构集成于一体,有效降低翼面可变后掠系统对飞行器的能源动力系统、结构重量和内部空间的压力。
