Abstract
The invention discloses an aircraft generating a larger thrust and lift by fluid continuity. First open channels used to extend fluid paths are formed in front parts and/or middle parts of windward sides of wings of the aircraft and extend from sides, close to the fuselage, of the wings to sides, away from the fuselage, of the wings, and the first open channels are concave channels or convex channels, so that a pressure difference in a direction identical with a moving direction is generated from back to front due to different flow speeds of fluid flowing over the windward sides of the wings in a lengthwise direction and a widthwise direction to reduce fluid resistance, and a larger pressure difference and lift are generated due to different flow speeds on the windward sides and leeward sides of the wings.
Claims16
An aircraft, comprising a fuselage, wings and a propeller including a plurality of blades, wherein
- a first plurality of open channels used to extend fluid paths are formed in windward sides of the blades in a lengthwise direction;
- the first plurality of open channels extend from sides of roots of the blades to tails away from the sides of the roots, and the first plurality of open channels are concave channels and convex channel, or the first plurality of open channels are concave channels or convex channels;
- a pressure direction of a centrifugal force generated during rotation of the blades is consistent with a flowing direction of fluid in the first plurality of open channels, so that a larger pressure difference and lift are generated due to different flow speeds of a high-speed fluid flowing over the windward sides of the blades in the lengthwise direction and a low-speed fluid flowing over leeward sides of the blades in a widthwise direction;
- the windward sides and leeward sides of the blades communicate with each other through a plurality of pressure ports;
- the pressure difference allows a high-pressure fluid above the leeward sides of the blades to flow to a low-pressure fluid above the windward sides of the blades through a shorter path inside the pressure ports, to reduce friction,
- wherein the concave channels are recessed downward on surfaces of shells on windward sides of wings, so that fluid flows smoothly through the concave channels, and openings of the concave channels are flush with the surfaces of the shells on the windward sides of the wings.
