A hybrid drive engine uses air foil shaped disks of a first configuration for a compressor portion thereof and air foil shaped disks of a second configuration for a turbine portion thereof, whereby the disks exhibit aerodynamic effects of lift. Particularly, the compressor disks are configured to cause aerodynamic lift off of a periphery of the disks, while the turbine disks are configured to cause aerodynamic lift off of an inner hole of the disks. The aerodynamic nature of the disks cause each disk thereof to form two opposing airfoil shapes either head to head or trailing edge to trailing edge across the through hole.

A vertical windmill employing aerodynamic lift includes stators that form an omnidirectional diffuser and can rotate out of the wind to reduce the destructive tendencies in high winds. A braking mechanism included in the windmill uses rotation of the airfoils to reduce the lift caused by the wind and disengagement of the airfoils to reduce nearly all lift on the airfoils. Centrifugal force is used to activate the brake in high winds, both to slow the rotor speed and, in extreme winds, to stop the rotor. A motor is provided to drive the windmill to simplify controls and increase energy production.

The construction of a flying platform in the shape of a square, diamond or another geometry figure with a hole in it is described. It has a unique constant cross-section profile providing aerodynamic lift. This structural solution offers the possibility of flight in any of four directions: each corner could be the front corner of the flying platform. The aerodynamic lift is generated by air turbulences formed on the leading edges and resulting from the air flow disturbances. The design combines two features: the wing/fuselage profile and the shapes of square or diamond, distinguished by excellent flight. It has improved longitudinal and transverse flight stability.

A lift arrangement for an aircraft (2) comprises an aircraft fuselage section with an outside (3), an aerodynamic lift body (6, 8)attached to the aircraft fuselage section and extending from the aircraft fuselage section outwardly, and a pair of movably held add-on bodies (12)arranged upstream of a leading edge (14) of the aerodynamic lift body (6, 8). The add-on bodies(12) comprise an aerodynamically effective surface and are equipped with incoming airflow to generate vortices (18) that impinge on the aerodynamic lift body (6, 8), thus leading to an increase inlift on the aerodynamic lift body (6, 8). Consequently it becomes possible with simple means to effectively influence lift generation on a lift body (6, 8), in particular to compensate for loss of lift as a result of icing. Preferably, the add-on bodies are moveable, and, when operational conditions do not require the use of said add-on bodies, can be moved to a neutral position in which they do not project into the flow around the aircraft, and are thus not effective from the point of view of fluid dynamics.

The invention pertains to aeronautical engineering and consists of an airborne platform that can be built to large sizes without requiring a rigid structure of comparable dimensions and which uses both buoyancy and the aerodynamic Magnus effect for lift. The aerodynamic lift is generated in lifting bodies (1), which also contain buoyant gas. The" lifting bodies (1) are stacked in a column, at the bottom of which there is a structural anchoring module (2) which also contains buoyant gas. ^The lifting bodies (1) and anchoring modules (2) are connected by slender structural elements which, when taken together as a whole form a non-rigid assembly. The platform may be tethered or configured as an aircraft, for which purpose other features may be added, such as a propulsion system (11), a crew gondola (6), cables to (7) and from (8) a swivel (12) and a payload (10) connected to said cables.

A wind turbine includes a nacelle mounted atop a tower. Power generating components are housed within the nacelle. A rotor hub is rotationally coupled to the power generating components. A plurality of blades are fixed to the rotor hub. The blades include a root section extending radially outward from the rotor hub and an aerodynamic section extending radially outward from the root section, wherein lift is generated by the blades primarily along the aerodynamic section. Aerodynamic fins extend radially outward from the rotor hub alongside the root sections of the blades and have an aerodynamic shape so as to capture wind and impart rotational torque to the hub from a central impinging wind zone that is coaxial to the rotor hub and the blade root sections.

【課題】風力発電装置において、風車コスト低減を実現する自律的ピッチ・コントロール型風車を提供する。
【解決手段】従来型に見られる可変ピッチ制御機構装置を排除するために、風車ブレード形状に、自然風速変動に呼応して、可変ピッチ機能を維持し、風車ブレードに自律的にピッチ角を調整することが可能な形状を付与する。新しい風車ブレード形状は、反りを持つ翼型の空力特性を利用して、風車ブレード翼の翼幅に沿って途中の反転位置で翼型を反転させることによって、自然風速変動に呼応して風車ブレード翼内で自律的に捩りモーメントの釣り合いを実現する。このとき、反転した翼型に発生する揚力は、反転しない翼型と同様に、風車ブレード翼のハブ周りの回転方向に揚力の成分を有している点を特徴とする。

An assembly for controlling the lateral stability of a swept-wing aircraft by varying the geometric dihedral of the wing as a function of the wing's lift coefficient, such assembly including a mechanism for producing a signal or other type response representative of the lift coefficient of the wing at any particular point in time during flight including changes in such lift coefficient due to changes in the particular flight condition or aerodynamic characteristics of such wing, and a mechanism responsive to such signal or other response for controlling and activating movement of variable dihedral panels associated with the respective opposite portions of the wing. Movement of the variable dihedral panels changes the geometric dihedral of such wing in direct response to changes in the wing's lift coefficient and this enables one to maintain the overall effective dihedral of the aircraft, and consequently, the rolling moment stability coefficient, relatively constant throughout the entire flight envelope of the aircraft.
