Title:
横軸ロータ
Document Type and Number:
Japanese Patent JP6560511
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a horizontal shaft rotor that is for use in a propulsion machine, that makes it possible to change the position of a blade of the horizontal shaft rotor such that the pitch angle thereof with respect to a rotational direction changes from 0 degrees and a leading edge moves 45 degrees to the front or to the rear, and that, by switching the pitch angle, makes it possible to perform changes of course, as well as to make a ship reverse, by means of propulsive force. A horizontal shaft rotor 1 wherein a support rod 4, which protrudes from a blade root 3C of a lift-type blade 3 that has a leading edge 3A that has a thickness that is 20%-30% of the chord length of the blade, is rotatably fitted into a hub 2 so as to be perpendicular to a rotating shaft center line S and such that a flat surface that runs from the leading edge 3A to a trailing edge 3B is a rear surface. The horizontal shaft rotor rotates the support rod 4 by means of an arbitrary rotation means 7 and can change the position of the lift-type blade 3 such that the pitch angle thereof with respect to the rotational direction changes from 0 degrees and the leading edge 3A of the lift-type blade 3 moves forward/rearward within 45 degrees.
