Title:
MAGNUS TYPE THRUST GENERATING DEVICE, WIND ROTARY DEVICE, HYDRAULIC ROTARY DEVICE, AND TIDAL ROTARY DEVICE WITH MAGNUS TYPE THRUST GENERATING DEVICE, AND WIND GENERATOR, HYDRAULIC GENERATOR, AND TIDAL GENERATOR WITH MAGNUS TYPE THRUST GENERATING DEVICE
Document Type and Number:
Japanese Patent JP2022136492
Kind Code:
A
Abstract:
To provide a magnus type thrust generating device which is light-weighted, is reduced in cost, and can efficiently generate rotational force owing to magnus force generated by a cylinder blade.SOLUTION: A vertical axis type magnus type wind generator (thrust generating device) 1 includes a support body 10, a rotary part 3 rotatable relative to the support body 10 around a first rotation axis O1, a plurality of cylinder blades 4 which can spin around a second rotation axis O2 parallel to the first rotation axis O1, a plurality of straightening plates 5 which constitute each group together with the plurality of cylinder blades 4 and a longitudinal direction of which are arranged along an axial direction of the cylinder blade 4 of each group, and a support part 6 which is fixed to the rotary part 3, supports the cylinder blades 4 on a circle around the first rotation axis O1, and supports the straightening plates 5 in an opposite side to a progress direction of the cylinder blades 4. The straightening plate 5 includes, in a side of a rear edge part 50d, a tapered part 53 in which the width of the straightening plate 5 is narrowed closer to an end part of the straightening plate 5 in the longitudinal direction.SELECTED DRAWING: Figure 1
