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 JP2022136491
Kind Code:
A
Abstract:
To provide a magnus type thrust generating device which has the increased durability thereof 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 and a plurality of shield plates 7 which constitute each group together with the plurality of cylinder blades 4 and a longitudinal direction of which are each 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 and the shield plates 7 in an opposite side to a progress direction of the cylinder blades 4. The shield plates 7 are disposed in a side of a front edge part 50c of the straightening plate 5 and is supported to be upright in a side of the first rotation axis O1 with respect to the straightening plates 5.SELECTED DRAWING: Figure 6
