A helicopter and aircraft power device has a plurality of fluid inlets on a windward side of a blade housing and a plurality of fluid outlets on a leeward side in a manner that the fluid inlets communicate with the fluid outlets. The path where the fluid flows in the lengthwise direction on the windward side of the blade housing is far greater than the path where the fluid flows in the widthwise direction on the leeward side of the blade housing, generating a very large pressure difference between the leeward side and the windward side. The action of the centrifugal force and a suction force from a suction motor significantly increase the flowing speed on the windward side of the blade and in the fluid passage, generating bigger pressure difference on either sides of the propeller and thus forming more powerful lift force and driving force.
A helicopter power device, comprising a propeller and a fuselage, the propeller comprising a cover body, a blade and a blade housing generating a first counteraction force, the helicopter power device being characterized in that a hollow fluid passage along a lengthwise direction of the blade is provided for the fluid to flow through;
An aircraft power device, comprising a propeller and a fuselage, the propeller comprising a plurality of blades generating a first counteraction force, the aircraft power device being characterized in that a hollow fluid passage along a lengthwise direction of the blade is provided for the fluid to flow through;
