Abstract: A testing system for testing a missile component having a sense axis includes a centrifuge, a support arm, an orientation assembly, and a controller. The centrifuge rotates the orientation assembly about a vertical axis in a substantially horizontal plane. The orientation assembly includes a first motor, a first gimbal, and a gimballed support. The first motor has a first rotatable shaft defining a first gimbal axis. The first gimbal is coupled with the first rotatable shaft to rotate about the first gimbal axis while the centrifuge rotates the orientation assembly about the vertical axis such that missile component is simultaneously rotated about both the vertical axis and the first gimbal axis to simulate a missile launch of the missile component. The gimballed support is coupled with the first gimbal for supporting the missile component such that the sense axis of the missile component is not parallel to the substantially horizontal plane.

Abstract: For a decoupled to gyro to have high sensitivity to angular rate, it is necessary to have the design flexibility to achieve all the critical frequencies in the design. The geometry of the gyro is first estimated and is followed by a performance analysis to maximize the gyro sensitivity. If the performance requirements cannot be met, the next iteration is started by a new estimate of the geometry. For a given design iteration, the desired modal response is implemented with a predetermined or given gyro flexure system. The flexure system disclosed here has enough independent design parameters to allow the desired modal response required for high gyro performance to be selected by independent design choice of the available geometric and configurational design parameters of the gyroscope.

Abstract: An oscillatory gyroscope is described with decoupled drive and sense oscillators and reduced cross-axis sensitivity. The gyroscope is fabricated using a plasma micromachining process on standard silicon wafers. The electrical isolation of the drive and sense functions of the gyroscope, contained within the same micromechanical element, reduce cross-coupling while obtaining high inertial mass and high sensitivity.

Abstract: A gyroscope having a rotor mounted onto a rotating shaft wherein the rotor has a circular flange extending from and perpendicular to one surface thereof. A suspension member having a flexible flange is affixed concentric with the rotating shaft and the rotor. A hysteresis synchronous electric drive motor is used for spinning the combined shaft with rotor. A light source is disposed on a stationary plate for emitting light perpendicular to a surface of the circular flange of the rotor. A light sensor is also disposed on the stationary plate and on a side of the circular flange opposite of the light source for producing an electrical signal as a function of the amount of light received. The light source and the light sensor are positioned such that only a portion of the light from the source strikes the sensor when the gyro is in a quiescent rotating state.

Abstract: An angular velocity sensor for detecting angular velocity components about three axes with high response is provided. A weight body carries out a circular movement along a circular orbit within the XY-plane with the origin being as a center. The weight body is supported so that it can be moved with a predetermined degree of freedom within a sensor casing. A Coriolis force Fco exerted in the Z-axis direction to the weight body is detected when the weight body passes through the X-axis at the point Px and an angular velocity &ohgr;x about the X-axis is obtained based on the detected force. Further, a Coriolis force Fco exerted in the Z-axis direction to the weight body is detected when the weight body passes through the Y-axis at the point Py and an angular velocity &ohgr;y about the Y-axis is obtained based on the detected force.
