摘要： A method of retrofitting a wind turbine (10) having a wind turbine tower (12) and a first energy generating unit (14) includes rotating at least a portion of the wind turbine tower (12). The wind turbine tower (12) is secured to a foundation (16) and has a first position on the foundation (16). The method includes rotating at least a portion of the wind turbine tower (12) from the first position to a second position. In the second position, the portion experiences less stress when the wind turbine (10) is operated in the same prevailing wind. The wind turbine tower (12) may have at least two sections (12a, 12b, 12c) and wherein rotating includes rotating one section relative to another section. One section may be secured to a foundation (16). In that case, rotating may or may not include rotating the section secured to the foundation (16). Rotating the tower may occur after the first energy generating unit (14) is removed from the tower and may include rotating the wind turbine tower by an angle from 90°±15° relative to the first position.

摘要： A vane assembly, particularly suitable for a transverse flow, or vertical axis, turbine or a propulsion device includes a vane with at least one concavo-convex part that is mounted by a pivot so that it is free to rotate about a pivot axis. The pivot connects the vane to a rotor with an axis of rotation. The pivot axis is inclined to the concave face such that, as the rotor turns, the vane is free to rotate about the pivot axis between a first position in which the vane defines a high-drag configuration for retreating with a transverse fluid flow, and a second position in which the vane defines a reduced-drag configuration for advancing against the transverse fluid flow.

摘要： Several embodiments of a device for economically harvesting wave energy are disclosed. A sealed vessel for air storage, the spar buoy, is mostly submerged under water is also used as an inertial body that surface floats move relative to. The spar buoy may take many geometrical forms, but all have a stem that is above the water surface. Piston pumps are placed at the top of the stem. The pump has a gearing reduction to optimize the rotational motion of the pump drive shaft. Small angular motion at the drive shaft results in multiple cycles of linear reciprocal motion of the piston. Various mechanisms could convert the relative motion between the floats and the spar buoy to a rotational motion of the shaft. The compressed air generated by the pump is stored in the spar buoy and regenerated as electrical energy by expanding the compressed air in a turbine.

摘要： The present invention relates in general to the field of hydropower devices using a reciprocating or oscillating blade system. It aims at utilizing the currents of oceans and seas and rivers to generate electricity. Its distinguishing design makes it possible to realize a leverage factor, much larger than existing devices using a reciprocating or oscillating blade system, and by this it will introduce leverage as a main characteristic for harnessing the power of relatively slow river and ocean currents by devices using a reciprocating or oscillating blade system.

摘要： The specification discloses a rotating turbine tower. The tower rotates to maintain the turbine facing into the wind. This allows structural optimization. The tower structure is comprised of a leading edge and a trailing edge, with joining panels between the edge structures. The tower edges are the main structural components of the tower. The separation of the edges tapers to follow the thrust bending moment on the tower, reducing the need to taper material thickness. The tapering shape of the tower structure matches the primary edgewise moment distribution. The tower can be assembled on site from components, thereby facilitating transportation to the tower site. The material properties and shape can be selected based upon the tower maintaining a near constant orientation with the wind. This can save weight and costs. The tower architecture can be of differing shapes such as a triangle or a structure tapering at each end.

摘要： A control mechanism for injector diaphragms in a turbojet engine is disclosed wherein an annular fairing is utilized to synchronize the movement of the individual air-fuel injector diaphragms. The fairing member is interconnected to each of the diaphragms and a single control element controls the rotational movement of the annular fairing. This minimizes the turbulence of the air flow passing around the control system.

摘要： New combustors which produce lower emissions, particularly lower emissions of nitrogen oxides and CO, are provided. The combustors are provided with a first combustion region that is cylindrical, short and of small diameter and an adjacent downstream second combustion region comprising an abrupt enlargement in diameter to provide a relatively larger capacity than the first combustion region. A first stream of air is introduced, either radially, axially, or tangentially, into the first combustion region and the amount of said air is varied in accordance with fuel flow to the first combustion region. A second stream of air is introduced tangentially into the first combustion region. A third stream of air is introduced tangentially into the second combustion region. In preferred embodiments of the invention the air stream pressure drop across an air assist fuel nozzle is varied in accordance with fuel flow to the nozzle.
