Abstract
A thrust generating device has a simple structure and can effectively control the magnitude of a Magnus force generated at a cylindrical blade in accordance with the direction of a flow acting on the cylindrical blade. A Magnus-type thrust generating device includes a first member that has a first rotational axis and that can rotate about the first rotational axis; and a second member that is disposed at a rear surface side in an advancement direction of the first member 1. (M−L)/L<2 is satisfied, where L is the distance from the first rotational axis to the most distant part of the surface of the first member and M is the distance from the first rotational axis to the closest part of the surface of the second member in a plane perpendicular to the first rotational axis of the Magnus-type thrust generating device.
