摘要： A main rotor blade incorporating a rotor blade tip region having a tip chord and a tip taper such that the ratio of the main rotor blade chord to the tip chord is approximately 0.30. The tip taper ratio preferably providing an approximately 28% area of reduction in said outer 10% of said blade span. The tip region preferably further including a hover optimized high lift airfoil and a tip sweep that reaches a constant value of approximately 30 degrees along the quarter chord line.

摘要： An articulated rotor system with a servo-flap rotor control system locates the focal point of a blade retention spherical elastomeric bearing inboard of a joint in the servo-flap pitch control tube which separates the flap hinge and supports the servo-flap pitch control tube on a single pivot bearing within a blade retention spindle. Rotor blade flapping produces relative movements between the servo-flap pitch control tube and the blade retention spindle which is converted through a servo-flap drive linkage into servo-flap pitch motions to provide flap/pitch coupling which reduces steady and transient blade flapping.

摘要： The hydraulic propeller system of the present invention has a central hub (14) including a stationary portion (28), and a rotatable portion (30). A plurality of propeller blades (12) are connected with the rotatable portion (30), wherein each of the plurality of propeller blades (12) has an adjustable pitch, and a counterweight (26) biasing the blades (12) in a first pitch direction . An actuating mechanism (16) is used for adjusting the pitch of each of the plurality of blades (12). A valve (56) for locking the propeller blades (12) at a last commanded pitch is further provided. At least the valve (56), the actuating mechanism (16) are located on, and rotatable with, the rotatable portion (30).

摘要： A linear wind powered electric generator (LWPEG), which is particularly adapted for installation at geographical sites subject to lower wind intensities. More specifically, there are provided design concepts for an LWPEG, possessing reasonable economic parameters for utilization at the lower-intensity wind sites. Moreover, the linear wind powered electric generator is based on a track based wind power generator, incorporating aerodynamic designs, which are adapted to reduce mechanical complexities presently encountered in this technology, while being cost-effective both in construction and in connection with the operation thereof.

摘要： An assembly for providing flexure to a blade of a rotary blade system, the assembly including an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween. At least one of the upper and lower yoke surfaces having a layer of cushioning material positioned thereon and secured thereto. The layer of cushioning material extending along and following the general contour of yoke surface, and the layer of cushioning material directly contacting a support plate. Another embodiment is an assembly for providing flexure to a blade of a rotary blade system, including, an upper support plate having an upper curved surface, a lower support plate having a lower curved surface, and a yoke positioned therebetween and directly contacting the support plates wherein one of the curved surfaces is a non-circular arc that does not form part of the circumference of a circle.
