摘要： Gyroscope a deux degres de liberte ayant un moteur (72) a aimants permanents, a entrefer axial. L'enceinte (14) du gyro supporte un stator ayant deux groupes de bobines enroulees en quadrature et connectees en serie (39a, 39b), (39c, 39d). L'axe principal de chaque bobine est parallele a un axe de reference de rotation (Z) avec lequel les premier (A) et second (B) axes d'entree sont mutuellement orthogonaux, chaque groupe de bobine etant dispose annulairement autour de l'axe de rotation de reference. Le rotor (42, 44) du moteur tourne autour d'un axe de rotation et peut se deplacer de maniere rotative autour des deux axes d'entree. Le rotor comprend un jeu d'aimants permanents (46, 48) supportes annulairement autour de l'axe de rotation, les moments magnetiques des aimants adjacents ayant des directions opposees et le flux provenant des aimants etant accouple aux bobines du stator. Une bague de retour de flux magnetique (50) complete le chemin de passage du flux au travers des bobines. Un reseau d'excitation (70) detecte les fem de retour dans les bobines et produit des signaux de commande pour entrainer des courants alternatifs ayant un dephasage relatif de 90o dans les bobines respectives mais etant en phase avec les fem de retour detectees dans les bobines respectives. Un autre reseau detecte le deplacement rotatif du rotor autour des axes d'entree et produit des signaux appropries pour des dispositifs de coupure (72, 76) qui servent a maintenir le rotor dans une position ou son axe de rotation coincide sensiblement avec l'axe de rotation de reference.

摘要： A two degree of freedom gyro having an axial gap, permanent magnet motor (72). The gyro housing (14) supports a stator having two sets of quadrature wound series-connected coils (39a, 39b) (39c, 39d). The principal axis of each coil is parallel to a spin reference axis (Z) with which first (A) and second (B) input axes are mutually orthogonal, each set of coils being annularly arranged about the spin reference axis. The rotor (42, 44) of the motor is rotatable about a spin axis and rotationally displaceable about the two input axes. The rotor includes a set of permanent magnets (46, 48) supported annularly about the spin axis, the magnetic moments of adjacent magnets being oppositely directed and the flux from the magnets is coupled to the stator coils. A magnetic flux return ring (50) completes the path for flux passing through the coils. An excitation network (70) detects back emf in the coils and generates control signals for driving alternate currents having a 90 relative phase shift in the respective coils but in phase with the detected back emf in the respective coils. A further network detects rotational displacement of the rotor about the input axes and generates appropriate signals for torquers (72, 76) which serve to maintain the rotor in a position where its spin axis is substantially coincident with the spin reference axis.

摘要： A torque converter comprises a stationary mount, input and output shafts, a primary frame (301) supported by the stationary mount for rotation about a primary axis and coupled for rotation with one of the input and output shafts (302,303), a secondary frame (50) supported by the primary frame (301) for rotation about a secondary axis perpendicular to the primary axis and coupled for rotation with the other of the input and output shafts, a plurality of flywheels (10) supported by the secondary frame (50) with their spin axes disposed at an angle to one another in the same plane, or in mutually parallel planes, and torsional springs acting between the flywheels and the secondary frame to cause the flywheels to oscillate in use, so as to effect a gyroscopic torque coupling between the primary and secondary frames. An excitation system (110) is mounted on the primary frame (301) for applying to each flywheel (50) a periodic torque that varies with the angular velocity of the secondary frame and the angular position of the axis of the flywheel relative to the secondary axis, so as to cause each flywheel to oscillate at its natural frequency in response to relative rotation between the primary and secondary frames.

摘要： An apparatus is described which reduces a time delay and a resultant phase shift in a gyroscope motor drive signal (90). The motor drive signal originates from a numerically controlled oscillator (32) whose output (60) is sampled at a predetermined rate. The apparatus includes a first element (108) which upsamples the oscillator output signal samples and a band pass filter (100) configured to receive an output from the first element and remove spectral components from the output of the first element. The apparatus further includes a third element (102) which generates a tuning parameter, β'0 (166), for tuning of the band pass filter and a scaling multiplier (112) configured to normalize an output of the filter.

摘要： A propulsion system for converting rotary motion into unidirectional motion includes a frame (10), a pair of counterrotating lower members (67, 67') rotatably mounted to the frame containing damping elements (72,72'). A pair of upper members (84, 84') containing damping elements are rotatably mounted to the frame and positioned above the lower members, each at an angle to the lower member so that each contacts a surface of the member below it at a single point (116, 116'). A motor (16) and drive train (18,20) are provided for driving the lower members. Each lower member includes a pair of studs (80, 82) mounted at its periphery which engage radially extending posts (106, 108) mounted to its corresponding upper cylinder so that rotation of the lower member causes the upper member to rotate in the same sense and at the same angular velocity. The superposition of the damped upper members upon the damped lower members generates unbalanced centrifugal forces which result in a constant unidirectional resultant force.

摘要： A self-contained momentum control system (MCS) for a spacecraft is provided for small satellites. The MCS features a miniaturized gyroscopic rotor with a rotational speed in excess of 20,000 RPM. The MCS includes at least three control moment gyroscopic mechanical assemblies (CMAs) rigidly mounted within a single enclosure, where each CMA mounted in an orientation whereby the longitudinal axis of each CMA is either orthogonal to every other CMA or is parallel to another CMA but in the opposite orientation. In order to further reduce the size of the MCS, an electronics package that is configured to interface command and control signals with and to provide power to the CMAs is included within the MCS enclosure. A plurality of shock isolation devices are used to secure each of the CMAs to the enclosure in order to reduce the launch load upon the CMAs thereby allowing the use of smaller rotor spin bearings. The MCS enclosure surrounding the CMAs and support structure is hermetically sealed.
