A mechanical structure used for extracting energy from oscillating marine waves is submitted. The apparatus comprises a plurality of buoyant tanks connected by a plurality of horizontal outriggers through a hinge assembly to a vertical frame located between the buoyant tanks. Marine waves create a pitching motion in the tanks forcing the outriggers to ascend and descend causing the vertical frame to rotate perpendicularly along the horizontal axis of the hinge. The power extraction system is comprised of a plurality of hydraulic cylinders connected to the vertical frame and outriggers. The pitching motion of the buoyant tanks and outriggers produce a vertical rotation along the horizontal axis of the hinge in the vertical frame, which forces contraction and expansion of the hydraulic cylinder assembly, thus extracting power from the relative motion between the members.

A device for retrieving energy of flowing water for the riverside is disclosed. The device uses a rotating disk to respectively connect with a first blade and a second blade through two rotating bodies. The first blade and the second blade are respectively located at the first position of an upstream side and the second position of a downstream side. Water pushes the first blade under the surface of water to swing from the first position to the second position, thereby rotating the rotating disk by a rotating distance. Thus, the second blade originally arranged over the surface of water reversely swings to the first position. Then, the second blade sinks in the water. Water pushes the second blade to swing to the second position, and the first blade rises and leaves the surface of water to swing to the first position.

The system also includes a cam bracket operatively coupled to an engine case structure, the cam bracket defining a slot. The system further includes an actuator bracket operatively coupled to the torque tube at a first end of the actuator bracket, the actuator bracket having a pin disposed within the slot of the cam bracket.

An assembly is provided for an aircraft propulsion system. This assembly includes a fixed structure, a translating structure, a blocker door and a rigid linkage. The translating structure is configured to translate relative to the fixed structure. The blocker door extends between a blocker door first end and a blocker door second end. The translating structure is pivotally attached to the blocker door at the blocker door first end. The rigid linkage includes a first pivot attachment, a second pivot attachment and a third pivot attachment. The first pivot attachment is coupled to the fixed structure. The second pivot attachment is coupled to the translating structure. The third pivot attachment is coupled to the blocker door at the blocker door second end.

An energy conversion and storage system, comprises a piston defining an enclosed volume. The piston has an inlet valve proximate a bottom of the piston and an outlet valve proximate a top of the piston. A guide having a vertical displacement is arranged so that the piston travels along the guide. The guide has a compressed gas outlet proximate a bottom of the guide and is arranged to move gas into the piston when the piston contacts the compressed gas outlet. The guide has a release valve operator disposed proximate a top of the guide and is arranged to open the outlet valve when the piston contacts the release valve operator. A source of compressed gas in communication with the compressed gas outlet. The system has means for converting motion of the piston along the guide into either (i) motion of another object or (ii) electric power.

An apparatus is described for converting river, tidal or ocean current energy into another form of energy, such as electrical, mechanical, or chemical energy. The apparatus can include a first underwater sail(s) coupled to a first cable and second underwater sail(s) coupled to a second cable. The sails are configured to catch water flows and move their respective cables along pulleys. The first cable and the second cable can form a main cable loop that is coupled to a bull wheel. A second cable loop configures the sails to best catch the water flow. The pulleys can guide the main cable loop along a rotational direction. The rotational movement of the bullwheel can be transferred to a generator to convert the water flow into another form of energy.

An apparatus for converting kinetic energy of a fluid into reciprocating motion includes a rod mounted for reciprocating motion along a substantially vertical direction, an airfoil mounted on the rod, and control surfaces for selectively moving the airfoil upwardly and downwardly in a fluid stream.

The already patented Madson Wind Turbine System (MWTS) embodies a wind turbine system for the collection of wind energy, compression of air (air or gas) in multi-stages to high pressure, for High PressureCompressed Air Energy Storage (HP-CAES), decompression of air in multi-stages, cooling of hot compressed air, harvesting of compression heat for heating cold decompressed air to increase volume & air flow for more efficient generation of electricity. This new invention constitutes a significant improvement of MWTS thru improved: ability to resist typhoons, cyclones & hurricanes, harvesting & directing hub area wind to the propellers, streamlining of wind for more efficient use by downstream wind turbines, harvesting of compression heat to heat decompressed cold air, simplification of equipment & construction by reducing the number of or combining the function of components, such as, the functions of transfer & regulator valves in previous inventions for lower capital & maintenance costs & greater efficiency; the introduction of new beneficial components, such as, uncloggable transfer valves; the avoidance of hazards, such as, bird strikes & nuisances, such as, flutter, pulse & vertigo and other improvements for the generation, storage and dispatch of electricity. This improvement also includes an HP-CAES Reserve Tank, constructed with Bolted Joints, such that it can be assembled quickly & cheaply without welding, de-stressing & spherical or thick plates; the elimination of, at least, one (1) built-in derrick and the development of self-regulating controls for feathering the propellers adapted to a Fan Wind Turbines instead of the conventional long aspect ratio sails (propellers).

A fan casing assembly for a turbine engine including a casing having an annular fan cooler. The annular fan cooler includes first and second connection assemblies to fix movement of the fan cooler during engine operation, while permitting circumferential thermal growth of the fan cooler without suffering from high cycle fatigue.
