Patent number: 5950963Abstract: 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.Type: GrantFiled: October 9, 1997Date of Patent: September 14, 1999Assignee: Versatron CorporationInventors: John M. Speicher, Che-Ram S. Voigt, Craig D. Perry, Allan A. Voigt

Patent number: 5907433Abstract: 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.Type: GrantFiled: June 16, 1997Date of Patent: May 25, 1999Assignee: Versatron CorporationInventors: Allan A. Voigt, John M. Speicher, Che-Ram S. Voigt

Patent number: 5887821Abstract: 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.Type: GrantFiled: May 21, 1997Date of Patent: March 30, 1999Assignee: Versatron CorporationInventors: Allan A. Voigt, Richard W. Schroeder, Che-Ram S. Voigt, John M. Speicher

Patent number: 5662290Abstract: An interface yoke plate is employed to impart directional control of multiple rocket nozzles. The interface yoke plate is rotated and translated in two orthogonal directions in accordance with steering commands from the missile autopilot and effects control along the yaw, pitch, and roll axes of the missile. One actuator yoke plate translates the interface yoke plate along one axis while another actuator yoke plate translates the interface yoke plate along a second axis. The interface yoke plate may also be rotated by one or both actuator yoke plates, causing a relative twisting of the multiple rocket nozzles and thereby directing their thrust in opposing directions and inducing a roll motion of the missile.Type: GrantFiled: July 15, 1996Date of Patent: September 2, 1997Assignee: Versatron CorporationInventor: Che-Ram S.

Patent number: 5630564Abstract: An actuation system for controlling the steerable nozzle of a missile or like vehicle is combined with an aerofin control system, both of which are driven in unison by associated drive motors and gear assemblies, one set for each aerofin. The nozzle steering system comprises two essentially identical yoke plates mounted along a plane generally transverse to the missile axis and oriented orthogonally relative to each other about the missile axis for pivoting the nozzle through mutually orthogonal axes, thereby achieving omni-directional steering. The yoke plates are coupled at opposite ends to pinion gears which are driven by the same gear assemblies which drive the associated aerofins. The arrangement permits common directional control of the steerable nozzle and the aerofins while maintaining the nozzle in a neutral direction when the aerofins are rotated to a missile roll control mode.Type: GrantFiled: March 19, 1996Date of Patent: May 20, 1997Assignee: Versatron CorporationInventors: John M. Speicher, Allan A. Voigt, Che-Ram S. Voigt

Patent number: 5566087Abstract: A gimbal control system including a hand controller having a trackball and a mode select switch for determining the mode of gimbal control. The mode control switch is capable of selecting between four different control modes. The trackball is enabled to control movement of the gimbal in different control relationships depending on the control mode which is selected. The hand controller includes a plurality of other switches for enabling the trackball to provide additional system control capabilities. The hand controller is ergonomically designed to minimize operator stress and fatigue during extended missions. It has a particular shape and the various control elements are strategically positioned to provide ready access to an operator's manual digits when the controller is held in the right hand with both hands and arms in a naturally relaxed attitude oriented at approximately a right angle.Type: GrantFiled: December 19, 1994Date of Patent: October 15, 1996Assignee: Versatron CorporationInventors: Allan A.

Patent number: 4892253Abstract: An actuation system for controlling the steerable nozzle of a missile or like vehicle. The system comprises two essentially identical actuators mounted along a plane generally transverse to the missile axis and oriented orthogonally relative to each other about the missile axis for pivoting the nozzle through mutually orthogonal axes, thereby achieving omni-directional steering. Each actuator includes an elongated yoke plate extending about the nozzle for applying steering forces against a yoke seat circumferentially mounted on the nozzle. Each yoke plate is pivotably mounted at one end and driven laterally at the other end by a gearing mechanism affixed to the nozzle skin.Type: GrantFiled: August 15, 1988Date of Patent: January 9, 1990Assignee: Versatron CorporationInventors: John M.

Patent number: 4850812Abstract: An integrated motor pump unit for use as a hydraulic fluid pressure source at a remote location incorporates a pump rotor affixed in the center of a motor rotor. The motor/pump rotor assembly spins on a fixed shaft in a combination providing both radial journal and axial thrust bearings. The stationary shaft assembly incorporates a piston drive mechanism which is angled, relative to the shaft axis, so that reciprocal movement of the pistons is developed as they rotate about the axis. The fixed rotor shaft is axially adjustable to control the end clearance between the pistons and cam surfaces, and contains fluid flow galleries to the journal and thrust bearings. A magnetically permeable sleeve is mounted between the motor stator and rotor to seal the hydraulic fluid within the rotor space, thereby maintaining the stator windings and associated electronic circuitry in a dry environment.Type: GrantFiled: September 18, 1987Date of Patent: July 25, 1989Assignees: Versatron Corporation, F.P.I., Inc.Inventor: Allan A.
