The present invention is an energy storage apparatus. The energy storage apparatus includes a rotor, a stator and a hub rotatably positioned about an axial shaft. The hub includes at least one spoke plane projecting radially from the hub, and the at least one spoke plane includes at least one spoke. The at least one spoke becomes progressively thinner along an increasing radius.

The present invention is a gimbal system for an apparatus supported in a frame. The gimbal system includes at least two parallel flexible beams positioned on either side of the apparatus. The apparatus is attached to the beam near a center of the beam to the apparatus, such that an active length of the beam is equal to a distance between the beams centers. A first end and a second end of the beam is mounted to the frame. At least one dampening mechanism is attached at a first end to the apparatus and at the other end to the frame. The apparatus exhibits axisymmetric roll stiffness independent of the motion of the frame.

Pocket attachment to rim

In a helicopter having a main rotor with blades controlled in pitch by servo flaps the servo flaps are arranged in advance of the leading edges of the blade to provide increased lift efficiency of the rotor system. The signals for controlling the pitches of the blade are generated by a computer implemented means responsive to pilot command signals and flight parameter signals and are transmitted from the stationary structure of the helicopter to the rotating structure through a non-mechanical stationary-to-rotary interface. An active stabilization system is associated with each rotor blade to overcome the instability previously associated with leading edge servo flaps and to reduce the complexity of the control signals needed to be produced by the control signal generating means.

Helicopter with leading edge servo flaps for pitch positioning its rotor

A system for determining the magnitude of loads on rotating helicopter components from sensor signals remotely measured on the helicopter fuselage is characterized by a controller which samples the sensor signals according to phase. These measured signals are presented to a coefficient programming module where they are combined with correlation signals to correlate the measured signal components with the desired parameter, such as flatwise bending moments of a helicopter blade. The correlation signals are established in a calibration process that determines the independent values of the measured signals using a Jones orthoganization process. The signals output from the module are recombined to provide a time dependent signal corresponding to the desired parameter. The present system avoids decomposition and recomposition of the measured signals and therefor operates in real time.

Real time load monitoring system with remote sensing

A novel system for determining the magnitudes of loads on rotating helicopter components from signals remotely measured on the helicopter fuselage is characterized by a processor which decomposes the measured signals into corresponding Fourier components and extracts selected components therefrom. A programming module performs a multiplication on the respective Fourier components to correlate the measured components with corresponding determinative parameter values. The parameter values are established in a calibration process which is characterized by determination of the independent values of a measured signal set using a Jones orthogonalization process. The signals output from the coefficient programming module are provided to a multiplying resolver which receives synthesized reference sinusoids from a digital processor and generates time dependent signal components therefrom. These signals are ultimately summed in an analog summer circuit whose output signal corresponds to the desired parameter signal.
