摘要： A wind turbine generator assembly comprising an enclosure forming an air pathway; one or more wind turbines within the enclosure air pathway for generating power from air flow through the air pathway; a powered induction fan located at the upstream end of the enclosure air pathway for directing and accelerating ambient air flow into the enclosure and along the air pathway; and a powered vacuum fan located within the air pathway downstream from at least one wind turbine, the vacuum fan operating to create a negative pressure downstream from the wind turbine to increase air flow across the wind turbine and increase the efficiency of power generation by the wind turbines. In some embodiments, the air pathway within the enclosure forms a straight path with no turns and has a substantially constant cross-section between the location of the induction fan and the vacuum fan.

摘要： A combined omnidirectional flow turbine system includes rotors that are disposed in a vertical position and enclosed in a motionless structure that receives air flows from any external direction which are manipulated by an airfoil to cause the rotors to rotate. The motionless structure is a hollow body and it is formed by a support structure and cover, being said interior space adapted to store electronic components, which can be directly supplied by the energy, produced. On its outer surface, air particles and pollutants filters can be installed, taking advantage of the aerodynamic shape of the motionless structure, which promotes air flow adhesion along its surface, making possible to capture particles along their preferred path.

摘要： A windmill rotation restrictor device restricts the speed of rotation of front blades of a decorative windmill in high winds. The device includes a windmill having a base, a rotor, and a vane. The rotor includes a front blade assembly and a front shaft extending from the front blade assembly. The front shaft is freely rotatable relative to the base. The vane includes a rear blade assembly and a rear shaft extending from the rear blade assembly. The rear shaft is freely rotatable relative to the base. The front blade assembly and the rear blade assembly rotate in opposite directions when blown by wind from a single direction. A linkage couples the front shaft to the rear shaft such that rotation of the rear blade assembly counteracts and slows rotation of the front blade assembly.

摘要： A spiral turbine blade having at least one concave compartment that is rotatable by a moving fluid for the generation of electricity is provided. A spiral turbine blade is aligned so that the axis of rotation is generally parallel to the mean direction of a moving fluid. Attached to the intake-facing side of the at least one spiral turbine blade are concave compartments comprised of an intake void, interior space, and exit void. The concave compartments are oriented to capture an additional range of velocity imaginary vectors; specifically those aligned via vortex inducing elements, such as spiral depressions on a conical intake shroud, thereby augmenting the torque induced the spiral turbine blade, and thus improving the conversion efficiency and electrical energy output.

摘要： A semi-ringed airfoil is designed in conjunction with a fluid turbine rotor blade to provide increased rotor-tip speed, increased coefficient of power, reduced wind shear and reduced noise. A dual-winglet rotor blade in combination with a semi-ringed airfoil increases the above mentioned benefits by increasing the rotor-blade tip surface-area that is in contact with the area of increased fluid velocity over the semi-ringed airfoil.

摘要： An aircraft includes a fuselage that has an exterior contour with an opening and a duct that is arranged interiorly of the exterior contour and extends from the opening. A ram air turbine is arranged within the duct. A deployable inlet scoop is mounted on the fuselage and is configured to be moveable between stowed and deployed positions. The stowed position blocks the opening into the duct and the deployed position exposes the opening and permits airflow through the duct. A method of providing electrical power includes identifying an electrical power demand condition, deploying an inlet scoop from an aircraft fuselage, and driving a ram air turbine with an airflow through the inlet scoop into the fuselage.

摘要： The invention discloses versions of a horizontal axis wind turbine and methodologies for the design of wind turbines, which are capable of extracting both kinetic and thermal energy from the wind. The wind turbines disclosed use a large diameter forward inlet fairing to accelerate the airflow to the more effective outer radii of the turbine rotor where the airflow is constrained by an airfoil-shaped flow control ring. This serves to prevent rotor tip losses, to inhibit wake expansion, and to accelerate the airflow through the turbine. A similarly large diameter aft pressure recovery fairing promotes rotation and contraction of the wake downstream of the turbine. Further methodologies for optimization and an algorithm for detail design are disclosed.

摘要： An energy conversion system having two or more enclosures supported in a vertically-stacked configuration by an enclosure support. The enclosures are airfoil-shaped and enclose multiple oppositely-rotating fluid turbines. Fluid directing structures formed in the enclosure direct fluid into and out of the enclosure, including through the turbines. The fluid directing structures are parallel slats formed into the enclosure.
