The invention discloses a single-wing self-rotating landing device which can enable blades to generate lifting force through rotation in the falling process of a load thrown from the air, so that thefalling speed is decreased, and the load falls to the ground safely. The single-wing self-rotating landing device comprises a storage box, a leading edge balance weight and blades. According to actualengineering application conditions, an effective load needing to be decelerated can be placed in the storage box to be jointly regarded as a wing root balance weight, and the mass and the position ofthe front edge balance weight and the size and the shape of the blades are reasonably arranged respectively to achieve overall normal operation. The device is specially designed for air-drop objectsand air-drop loads with special requirements. The principle of the device is similar to that of maple seeds in the nature. The blades are pushed by air during falling, so that the whole device rotatesto generate lifting force and slow down the falling speed; and the device has the characteristics of simple structure, effectiveness and reliability.
本申请公开了一种单翼自旋降落装置,可以使从空中投放的载荷在下落过程中,通过旋转使桨叶产生升力,从而减慢下落速度并安全落地。所述单翼自旋降落装置包括收纳盒、前缘配重和桨叶。根据实际工程应用情况,可以将需要减速的有效载荷放入收纳盒内,共同视作翼根配重,并将前缘配重质量、位置以及桨叶尺寸、形状,分别合理布置,使整体正常运转。本发明专门针对有特殊需求的空投物、空投载荷所设计。该发明与自然界中的“枫树种子”原理类似。在下落时空气推动桨叶,使整个装置旋转,进而产生升力,减缓下落速度,具有结构简单,有效可靠的特点。
