Abstract: Disclosed are an electrically-driven gyroscope having a housing capable of alternate rotation and a control method thereof, which relate to the field of electrically-driven gyroscopes. The electrically-driven gyroscope includes a rotating housing, an internal rotator, a drive motor composed of an electrical port part and a rotating part, a drive circuit, and a battery. The internal rotator is mechanically connected to the rotating part of the drive motor, and they can coaxially rotate. The electrical port part of the motor, the drive circuit, and the battery are mutually electrically connected, and are all connected inside the rotating housing. The electrical port part and the rotating part of the drive motor rotate with respect to each other under an interaction force. The used drive motor may be an inner rotor motor, an outer rotor motor, or an axial motor Further, during use, the present disclosure does not need to rely on an external force-applying object or the aerodynamic force by means of the disclosed design manner and the alternate control method for the housing, thus realizing autonomous continuous rotation and maintaining an upright alternate rotation posture until the battery is depleted.

Abstract: Feedback control circuitry includes rate limiter circuitry configured to generate a rate limited position command based on a position command for a controlled component and based on a speed command for the controlled component. The feedback control circuitry also includes error adjustment circuitry configured to apply a control gain to an error signal to generate an adjusted error signal. The error signal is based on position feedback and the rate limited position command, and the position feedback indicates a position of the controlled component. The feedback control circuitry further includes an output terminal configured to output a current command generated based on the adjusted error signal.

Abstract: A gyroscope power starter has a housing having a bottom and a concave head slanted at a predetermined angle relative to the housing, the concave head engaging a gyroscope rotor. An electric power source is mounted on the housing. A motor is rigidly mounted to a housing. The motor is connected to the power source for producing a rotational power in response to a switching force. A power rotor is connected in unity with the motor and protruding from an opening into the concave head of the housing to transmit the rotational motor power to the gyroscope rotor. An alignment member is formed in a concave center area. The alignment member protrudes into a groove of a gyroscopic rotor when the gyroscopic rotor is rotating.

Abstract: The mechanical output power of a turbine engine can be electrically boosted by using a power control system which may include a power source, an electric machine, a prime mover coupled to the electric machine, and a power control module coupled to the power source and the electric machine. The power control module may be configured to operate the electric machine between a motoring mode driving a mechanical load and a generator mode supplying power to an electrical load at speeds normally associated with generating modes only.

Abstract: A rotor assembly is provided for deployment within a momentum control device including a rotor assembly housing. In one embodiment, the rotor assembly includes a rotor shaft rotatably mounted within the rotor assembly housing, a floating bearing cartridge disposed around a first end portion of the rotor shaft, and a radially-compliant damping member. The radially-compliant damping member is mechanically coupled between the floating bearing cartridge and the rotor assembly housing, as taken along an emitted disturbance path. The radially-compliant damping member reduces the transmission of vibratory forces from the floating bearing cartridge to the rotor assembly housing to reduce emitted disturbances during operation of the momentum control device.

Abstract: A tuned gyroscope incorporates a dynamic absorber for lessening the transmissibility of resonant vibrations. A damping mass is symmetrical about a rotating element of the gyroscope. A symmetrical arrangement of elastomeric material is utilized to mount the mass to such rotating element. The mass and elastomeric material are so chosen with respect to geometry and material composition that out-of-phase vibrations are induced within the damping apparatus upon the onset of resonant vibrations to minimize the transmissibility of such vibrations with respect to the elements of the tuned gyroscope.
