  • Publication number: 20090067983
    Abstract: A Centerline Compression Turbofan Engine reconfigures the current technology eliminating the shaft and placing the combustor at the intake of the engine Turbine blades mounted on the inside of consecutive rings are curved and angled so that they compress air towards the centerline and backward along the axis of the engine as they rotate. High speed exhaust gasses from the combustor coming into contact with the turbine blades provide the rotational drive for each turbine blade array. Exhaust gasses from the combustion chamber and air from the intake are compressed through consecutively smaller turbine blade arrays along the entire length of the engine until it exits the variable exhaust nozzle. Said configuration produces a jet of a high speed exhaust gas for propulsive purposes.

A turbine has a large opening to allow a stream of water to pass through. The turbine is supported by a plurality of rubber tires such that a reaction force from the stream of water holds against the tires. A frame with a floatation chamber is used to lower the turbine into position in the stream of water, and to raise the turbine to a horizontal position on the surface of the body of water. The floatation chamber is partially filled with water to lower the turbine in the body of water such that an air pocket exists in the chamber to orient the turbine in a vertical position. When the chamber is purged of water, the turbine is raised to the surface. Rotation of the turbine drives the tires, which drive pumps to pump fluid to a motor, which drives an electric generator to produce power.

  • Patent number: 5167483
    Abstract: An energy conversion device which benefits from forces associated with angular momentum. A mass such as fluid is directed through a conduit from one elevation to a lower elevation with the conduit configured to conform to a decreasing cross-sectional area and oriented in a spiral of substantially conical shape so that fluid entering into the conduit accelerates both by virtue of the decreasing cross-sectional area of the conduit and by the velocity added to the fluid by successively constricting the fluid to an ever tighter spiral path of lesser radius ultimately to an output of the conduit which is in communication with a converter such as a turbine. The converter has an interior passageway in axial alignment with an outlet of the conduit and includes an interior vane which coacts against the fluid exiting from the outlet of the conduit imparting rotation to the rotor which circumscribes the passageway. The rotor is supported on a bearing block and operatively couples to a stator for power output.
