HELICOPTER AND AIRCRAFT POWER DEVICE

摘要

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.

主权项

1. A helicopter power device, comprising a propeller and a fuselage, the propeller comprising a cover body, a blade and a blade housing, the helicopter power device being characterized in that a fluid passage which is hollow for the fluid to flow through is provided in the lengthwise direction in the blade; at least one fluid inlet is provided on a windward side of the blade;
at least one fluid outlet is provided on a leeward side of the blade in a manner to communicate with the fluid inlet; and the fluid passage allows different paths for the fluid to pass in the lengthwise direction of windward side and in the widthwise direction of the leeward side to generate pressure difference give more lift force.
