    摘要： An aircraft has a plurality of pairs of disc-type wings behind each other kept by holding structures on the body of the craft. Each pair has one disc-type wing on the right and one disc type wing on the left of the body, symmetrically arranged relative to the body. The discs have propeller blades which can be retracted into the discs and be extended from the discs. The discs are also provided with windows wherein adjustable covers are located which can close and open the windows.For forward flight the discs are slightly inclined to act as wings which carry the craft. For vertical take off and landing the propeller blades are extended from the discs while the discs are revolved for action of the propeller blades as lift providers for the craft. An analysis which is given in this specification shows that a considerable benefit is obtained at equal installation of power if at least two pairs of propeller revolving discs are provided on the aircraft.

    摘要： An aircraft drive system having two propellers, each of which is driven independently by a drive belt which is connected to a separate engine. The engines are mounted in cantilever fashion in a spaced relationship on a hollow sleeve. The sleeve is attached by a pair of spaced brackets to the frame of the aircraft. A shaft is rotatably telescopically mounted within the sleeve by bearings located on the ends of the sleeve. A pulley is fixedly mounted on one end of the shaft and is driven by one of the engines for rotating one of the propellers which is fixed on the other end of the shaft. Another pulley is rotatably mounted by bearings on the sleeve and is driven by a drive belt connected to the second engine. The second propeller is telescopically located about the sleeve adjacent the first propeller and is firmly connected to the second pulley which rotates said second propeller completely independent of the first propeller and in an opposite direction than the first propeller. The sleeve which is attached to the aircraft frame provides the entire support for the two drive engines, pulleys, propellers and associated drive belts.

    摘要： A helicopter-like craft has plural propellers with substantial vertical axes which can be inclined forwardly to provide the forward movement of the vehicle. The propellers are driven by hydraulic fluid motors. One embodiment features the application of a four flow hydraulic pump which supplies two pairs of hydraulic pressure fluid flows, wherein the rate of flow in fluid in each flow of the pairs are equal. One of the pairs of flows may be of permanently fixed rate of flow but the flows of the other pair of flows is variable, but variable in such a system, that even at variation of rate of flow the rate of flow of the two flows of the variable flow--pair remains equal relatively to the other flow of the pair. This system of hydraulic drive is utilized to let the two front propellers of an airborne craft run with equal velocity even when the speed thereof is varified by the mentioned variablity in order to incline the vehicle into its forward movement. The two rear propellers are also forced to run at equal speeds. In another embodiment the plural deliveries of the flows are utilized to maintain flight of the vehicle when one of the fluid lines breaks or fails to deliver. The features of the arrangements are, that the airborne craft of the invention is easily controllable, does not depart from a desired straight forward flight path and that it will be able to continue a flight or to afford a safe landing, when one of the delivery flows fails.

    摘要： A hydraulically driving and controlling - unit comprises a power plant which drives a fluid flow producing device for the separate production and supply of pairs of flows of hydraulic fluid under pressure. The unit supplies at least one pair of flows to at least two fluid motors. Rates of flow in flows are proportionate to each other whereby motors of same pair of flow are actuated and maintained to act with to each other proportionate speed of motion. Unit may be transportable and adaptable to machines or vehicles. The drive unit may include a plurality of power plants and fluid flow producing devices. In such multiple unit one way valves are set into fluid lines which may combine partially after those one way valves for directing each one flow from a different power plant to the same motor. Thereby the unit can continue to operate, when one of the plurality of power plants fails. The proportionateness of speed of motion of the motors which is enforced by the proportionateness of rates of flow in the separated flows can be utilized to equalize or synchronize the motion of machines or vehicles or of driving members thereof.
