The invention discloses an aircraft high lift device with double slotted flaps and a fixed wing aircraft, the aircraft high lift device comprises a main wing, a main flap, a rear flap, a main wing connecting bracket, a main flap fixing bracket, a rear flap fixing bracket and connecting rods, and the main wing, the main flap and the rear flap are connected through two connecting rods or three connecting rods. Follow-up of the rear flap relative to the main flap is achieved through the connecting rod, so that when the main flap actively deflects, the rear flap can automatically retreat and deflect relative to the main flap, and the maximum lift coefficient is increased. The complexity of the follow-up double-slit flap high lift mechanism is simplified, meanwhile, the maximum lift coefficient is increased, the takeoff and landing sliding distance of an aircraft is reduced, and short-distance takeoff and landing of the aircraft are achieved.
本发明公开了一种双缝襟翼的飞机增升装置及固定翼飞机,包括主翼、主襟翼、后襟翼、主翼连接支架、主襟翼固定支架、后襟翼固定支架和连杆,所述主翼、主襟翼、后襟翼之间通过两连杆或者三连杆连接。本发明通过连杆实现了后襟翼相对于主襟翼的随动,使得主襟翼在进行主动偏转时,后襟翼相对于主襟翼能自动进行后退及偏转,从而增加最大升力系数。本发明简化了随动式双缝襟翼增升机构的复杂性,同时增加最大升力系数,降低飞机起降滑跑距离,实现飞机短距起降。
