Title:
INCREASING PROPULSIVE FORCE AND PROPULSION BLADE FOR VISCOUS FLUID FLOWING ALONG FACE
Document Type and Number:
Japanese Patent JP2017019391
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a shape of a propulsion blade having lift force and propulsive force.SOLUTION: A left end shown in the drawings is advanced by obtaining increasing propulsive force of a flow along a curve surface due to reception of headwind by a flight sail j1 and is navigated by receiving buoyant force due to lift force. A center shown in the drawings is navigated forwards in such a manner that a bird-shaped sail j2 receives tail wind while a rear edge thereof being perpendicular in an upper direction. A right end shown in the drawings is navigated forwards by obtaining increasing propulsive force of a flow along a curve surface in such a manner that a symmetrical sail j3 is perpendicularly stood while a connection pin p2 for the end being connected to another connection part n2 and receives headwind, and is navigated forwards by converting a resistance of headwind into a drag as a yacht.SELECTED DRAWING: Figure 4
