20080304971 | Method of Manufacturing a Fibre-Reinforced Part for a Wind Power Plant - The invention relates to a method of manufacturing fibre-reinforced parts for a wind power plant such as eg a blade, wherein the method comprises laying out a first, outermost layer of film in the interior surface of an open mould; following which different layers are arranged on top of the first layer, comprising layers of fibre material; and wherein resin is applied for joining the laid-out layers to each other. By use of a film for the outermost layer a moulding process results that provides a major improvement of the working conditions. A further advantage is also that, compared to the use of gelcoat, a surface is accomplished which is more resistant to physical influences in the form of eg cyclical stresses on the element. The invention also relates to a fibre-reinforced part for a wind power plant, eg a blade, wherein the part is structured from a first, outermost layer, and also to a blade for a wind power plant and comprising a fibre-reinforced part according to the invention. | 12-11-2008 |
20080310962 | Air-Jet Propeller - The invention relates to an air-jet propeller comprising three bodies. The first body or head takes the form of a half-ellipse, the upper part of which is provided with a grille, while the lower part thereof is closed at one section, said first body being equipped with a closure ring. The second body or central part takes the form of a tubular cylinder comprising a helical round honeycomb rotor which is coupled to a spark ignition engine. The third body or rear part takes the form of a truncated cone and is equipped with a series of openings, gates and butterfly valves which balance, stabilise and direct the aircraft, such as to reduce fuel consumption and, consequently, pollution since the aircraft can fly at low speeds (km/h), thereby facilitating landing and take-off with minimum runway lengths and eliminating the risks associated with the high speed required for take-off and landing. | 12-18-2008 |
20090169388 | Multiple Rotor Windmill and Method of Operation Thereof - The hub of the horizontal axis contains rotors rigidly attached in the radial direction by their own axes on the ground of logarithmic spiral-shaped load-bearing elements that rotate in response to the force of ram pressure and as it rotates in a wind flow around it generates lateral aerodynamic force arisen due to the Magnus effect; the total quantity thereof creates a rotary moment of the horizontal axis. | 07-02-2009 |

20110262275 | METHOD FOR PRODUCING THRUST (EMBODIMENTS) AND APPARATUS FOR TRAVEL IN A FLUID MEDIUM - The subject of the patent is a group of inventions relating to an apparatus for movement in air and water. The apparatus for movement in fluid comprises an aerodynamic cross-section wing with a convex upper surface, and a source of high pressure fluid interconnected with a means for forming pressure jets over the convex upper surface of the wing. Six embodiments of the apparatus are characterized by the design of the means for forming pressure jets. The method for developing thrust consists of using the means for forming pressure jets over the convex upper surface of the wing. Five embodiments of the method are characterized by the design of the means for forming pressure jets. The group of inventions is aimed to increase efficiency. | 10-27-2011 |
20140334931 | PROPULSION UNIT FOR A SHIP - This invention provides a propulsion unit for a ship with a new structure that is able to propel the ship without using a propeller. | 11-13-2014 |
20150086373 | JET PROPULSION WATERCRAFT - A jet propulsion watercraft includes a vessel body, a steering nozzle, and a bucket. The steering nozzle includes a jet port from which a jet of water is ejected to propel the vessel body. The bucket is configured to move to a retracted position away from the jet of water ejected from the jet port and a jet receiving position to receive the jet of water ejected from the jet port. The bucket includes a right opening, a left opening, a first opening, and a second opening spaced apart from the first opening. The jet of water flows rightward from the right opening, leftward from the left opening, and rearward from the first opening and the second opening when the bucket is located in the jet receiving position. The first opening is located at least partially rightward of a right end of the jet port. The second opening is located at least partially leftward of a left end of the jet port. | 03-26-2015 |

20130142650 | TURBINE DEVICE - A turbine device, including: a turbine housing including an inlet, a flow channel, an outlet, a middle partition, an arced partition; a turbine impeller; a gas outlet; and an exhaust manifold. The turbine impeller and the gas outlet are arranged inside the turbine housing. The exhaust manifold is connected to the inlet. The flow channel is arranged inside the turbine housing. The outlet is arranged on the flow channel close to the turbine impeller. The middle partition is disposed inside the flow channel and divides the flow channel into a left flow channel and a right flow channel. The arced partition is arranged in both the left and right flow channels. One end of the arced partition is in a rigid connection with the middle partition, and the other end of the arced partition is close to the outlet of the turbine housing. | 06-06-2013 |
