The invention relates to a propeller-driven helicopter which is characterized in that a first vent hole in the windward side of a blade is communicated with an exhaust hole in the tail part of the blade through a fluid channel, and the leeward side of the blade is communicated with the windward side through a vent pipe or/and a second vent hole, so that the pressure difference is transferred from the high pressure of the leeward side of the blade to the low pressure of the windward side. The invention also relates to a propeller-driven aircraft. The fluid pressure in different directions borne by the windward side and the leeward side of the blade shell respectively is changed into the fluid pressure in the same direction, the pressure direction is opposite to the external pressure direction and counteracts the external pressure, and the counteracting pressure can obtain the pushing force, so that in the state of not increasing extra energy consumption, two larger lift and thrust sources are generated by reducing fluid resistance.

    本发明涉及一种螺旋桨驱动的直升机,在桨叶迎风面的第一通气口通过流体通道与的桨叶尾部的排气口相通,桨叶背风面通过通气管或/和第二通气口与迎风面相通,使桨叶背风面的高压力向迎风面的低压力转移压力差。本发明还涉及一种螺旋桨驱动的飞机。本发明把浆叶壳体迎风面和背风面分别承受的不同方向的流体压力,统统改变为同一方向的流体压力,其压力方向与外界的压力方向相反而相互抵消,而相互抵消多少压力、就获得多少推动力,因此在不增加额外能耗的状态中,通过减少流体阻力来产生二种更大的升力和推动力来源。
