The invention relates to the fields of folding propellers, air flight and underwater navigation, and aims to play a greater role in the propellers, enable the propellers to have the capability of adapting to different resistances by own power in different domains, change the area of flapping wind and pushing water during working so as to adapt to different environments and generate better kinetic energy, and the folding propellers are unfolded towards the periphery of a rotating plane of the propellers after being folded, so that the propellers can be folded and unfolded. After the rotation area is enlarged, the propeller can continue to rotate, adapt to air flight, gather, merge, fold and the like in the direction of the center point of the rotation plane of the propeller, and after the rotation area is reduced, the propeller can continue to rotate, adapt to underwater navigation and continue to drive the main body to advance in different regions.
折叠桨,空中飞行,水中航行领域,意在于将螺旋桨发挥更大作用,能在不同的域中,使其有自身动力适应不同阻力的能力,做工时改变扑风推水的面积,以适应不同环境产生更好的动能,折叠桨,折叠后向螺旋桨旋转平面外围展开,扩大旋转面积后,能继续旋转,能适应空中飞行,向螺旋桨旋转平面中心点的方向聚拢,合并,折叠等,缩小旋转面积后,能继续旋转,能适应水下航行,能在不同的域中继续带动主体行进。
