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.
Claims17
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, wherein the object comprises a cylinder;
- an additional cylinder coupled to the structure and journaled for rotation relative to the structure so as to disrupt the fluid around the structure;
- and
- a drive source that causes the object and the additional 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 drive source is user controllable to cause lift or drag, depending upon system requirements at that instant, and a control system utilizes lift measuring mechanisms with feedback to allow the system stabilization according to adaptive input/output control algorithms such that the object and the additional cylinder are controlled independently of each other.
