<p>According to the present invention, a blade with lift-to-drag ratio greater than one can generate a lift force greater than the drag force on the blade when a fluid flows across the blade. The blade can be positioned within an enclosed engine to produce a force greater than the force required to move the fluid across the blade, thereby creating a thrust for the enclosed engine. The direction and the magnitude of the thrust may be controlled by controlling the direction of fluid flow. According to the present invention, fluid flowing inside a thrust engine may be gaseous or liquid. A thrust engine of the present invention uses one or more wings in a configurable environment to create a directional force. Thrust engines according to the present invention can be configured by varying fluid parameters, such as density or velocity, the wing parameters (such as wing geometry, lift coefficient or plane surface area of the wing), the number and the locations of wings, how the fluid receives energy, fluid motion, fixed or movable wings and the fluid path.</p> |
