Abstract: A novel design concept for a torquer motor is useful for stabilizing apparatuses in a vibrating structure. According to one aspect, a novel design for a coil pair is provided. A first coil in the pair is box shaped with a hollow interior portion and windings provided on a surface opposite the hollow interior. A second coil in the coil pair is flat and torus shaped with windings provided on the surface. According to one example, the second coil is bent so as to conform to the shape of the first coil, and disposed over the first coil so that the respective windings are oriented orthogonally to each other in a common plane direction so as to define an active area. The active area may be further disposed in the magnetic field of a magnet pair in a torquer motor application. The design provides advantages such as inherent rigidity and more efficient heat transfer, while providing high torque or a desired range of movement.

Abstract: An actuator system for controlling the external fins on a gun-launched projectile to control the flight path of the projectile. These actuator systems include an electric motor having a rotor and output shaft which is driven between travel limits that are less than 180 apart (less than 90 in either direction from a central rest position). Coupling from the motor shaft to the control shaft for the external fins is via a coupling between an eccentric ball on the motor shaft and an eccentric receptacle member on the fin shaft. As the angle of the motor shaft varies, the eccentric ball slides in a slot in the fin coupling member, causing the fin shaft angle to vary correspondingly. In another embodiment, the eccentric ball for controlling the fin shaft angle is mounted on a link arm that is coupled to the motor shaft, thereby permitting the motor to be mounted off the projectile axis and thus accommodating a shortened space in the projectile required for the actuator system and associated power supply.

Abstract: Pairs of aerofins used for stabilization and control of missile flight are deployed through shared longitudinal slots provided in the missile body. Before launch, the pairs of aerofins, each pair comprised of a canard and a deflector, are retained in a folded position by a releasable latch mechanism within the missile body. The deflectors are mounted in a laterally displaced position from the longitudinal slots and are constrained from sliding into alignment with the slots by the presence of the folded canards. When the canards are released by the latch mechanism and permitted to extend outward to their deployed positions, the deflectors are able to laterally shift, effectively displacing the canards in the alignment position and subsequently deploying. The latch mechanism is designed to simultaneously release all the canards following missile launch, with biasing torsional springs operating to urge the canards outward through the associated slots to the extended position upon release.

Abstract: A mechanism for locking the fins of a missile in place when the missile is not in use utilizes tabs inserted in slots of the output shafts of the fins to immobilize the output shafts and the fins. In one embodiment, the tabs are cantilevered on a locking plate from which they extend radially toward the output shafts. A cam plate slidably engages the tabs on the locking plate and simultaneously lifts all the tabs out of the slots when it is rotated. for disengagement of the locking mechanism. Operation of the locking mechanism can be effected either manually, using a specialized tool, or remotely, using for example a pyrotechnic actuation device.

Abstract: An optical system is provided with a plurality of field of view optical groups for insertion into the optical path. The field of view optical groups each subtend a prescribed field of view angle and are rotatably mounted on a rotary assembly for insertion into an operational position in the optical path. The rotary assembly is provided with hard stop contacts which rotate along a path and interact with stationary stops to locate the optical groups in the operational position. Additionally, movable stops are reciprocated into the rotation path of the hard stop contacts to provide additional modes, including a calibration mode. The system is also provided with extender optical groups which can be inserted in the optical path to provide intermediate fields of view between those of the field of view optical groups, thereby doubling the total number of fields of view available.

Abstract: In a missile thrust vector control (TVC) system, two yoke plates are used which surround a pair of pivotably-mounted rocket nozzles. The rocket nozzles pass through corresponding elongated slots disposed on each yoke plate, the elongate slots engaging said rocket nozzles and operating to actuate the movement of the rocket nozzles in accordance with command signals issued by the missile autopilot. The actuator yoke plates are mounted for movement in orthogonal directions, and for rotation in unison. The orthogonal movement of the yoke plates effects corresponding movement of the rocket nozzles in the yaw and pitch directions. Simultaneous rotation of the yoke plates produces a relative twisting of the pivotably-mounted rocket nozzles causing thrust angles to deviate from the missile central axis in opposite directions but equal degree, thereby imparting a roll moment to the missile. In this fashion, any combination of movements of the missile during flight is made possible.
