Abstract
A system takes advantage of the Magnus effect to increase the efficiency of a moving structure by increasing the forces generated by a fluid moving relative to the structure, e.g., to improve lift, drag, etc. The system includes a structure having a first side and a second side opposite the first side. An object coupled to the structure, e.g., a cylinder, is exposed to a fluid such as air. The object is journaled for rotation relative to the structure so as to disrupt the fluid around the object. A drive source causes the object to rotate relative to the structure so as to cause a select one of an upward lift, or a downward drag.
Claims20
A system comprising:
- a structure having a first side and a second side opposite the first side;
- an object coupled to the structure, the object further exposed to a fluid, wherein the object is journaled for rotation relative to the structure so as to disrupt the fluid around the object;
- and
- a drive source that causes the object to rotate relative to the structure so as to produce a directional force causing a select one of an upward lift, or a downward drag against the structure.
A system comprising:
- a structure having a first side and a second side opposite the first side;
- an cylinder coupled to the structure, the cylinder further exposed to a fluid, wherein the cylinder is journaled for rotation relative to the structure so as to disrupt the fluid around the cylinder;
- and
- a drive source that causes the cylinder to rotate relative to the structure so as to produce a directional force causing a select one of an upward lift, or a downward drag against the structure;
- wherein:
- the cylinder includes at least one of a rib, a fin, a ridge, a vane, or a dimple;
- the cylinder is positioned spaced behind a leading edge of the structure;
- and
- the drive source is user controllable to cause at least one of lift or drag.
A method comprising:
- providing a structure having a first side and a second side opposite the first side;
- coupling an object to the structure such that the object is exposed to a fluid, wherein the object is journaled for rotation relative to the structure so as to disrupt the fluid around the object;
- and
- controlling a drive source that causes the object to rotate relative to the structure so as to produce a directional force causing a select one of an upward lift, or a downward drag against the structure.
