Patent number: 7795565Abstract: A guided missile or projectile and associated guidance control are provided to control a path to a point of intersection with a potentially moving target. A new path is repetitively recomputed and acceleration orthogonal to the path is applied to minimize heading error and thereby to converge on the target. The gain of the control function is partly proportional to heading error, but the gain is reduced approaching the point of convergence. In this way, the guidance control is more responsive to actual variance of the true heading error and is less responsive to random error in sensing the target heading, which random error would otherwise increase in its contribution to corrective guidance movements approaching the point of intersection.Type: GrantFiled: January 3, 2008Date of Patent: September 14, 2010Assignee: Lockheed Martin CorporationInventor: Gregory F.

Patent number: 6279478Abstract: A fuzing system for non-spinning or substantially non-spinning weapons is implemented by means of wide angle optics providing at least forward-hemisphere coverage, an array of infrared detectors and a microprocessor for image and data processing, aim-point selection, directional-warhead aiming and skewed-cone fuzing. The skewed-cone fuzing has a generatrix which is the vector sum of missile velocity, warhead velocity and the negative of target velocity.Type: GrantFiled: March 27, 1998Date of Patent: August 28, 2001Inventors: Hayden N. Ringer, Abraham Shrekenhamer

Patent number: 6276277Abstract: A target-penetrating aerial bomb includes a penetrator of hard steel or similar material that contains an explosive charge. A rocket motor is formed as an annular chamber and surrounds the penetrator. The bomb includes a guidance and control unit that guides the bomb on a glide path after release from the delivery aircraft, and steers the bomb onto a dive line. Once the bomb is aligned on the dive line, the guidance and control unit fires the rocket booster to accelerate the bomb to the target. A fuse ignites the explosive after target penetration.Type: GrantFiled: April 22, 1999Date of Patent: August 21, 2001Assignee: Lockheed Martin CorporationInventor: Bruce E. Schmacker

Patent number: 6254031Abstract: The disclosure relates to a low cost and highly accurate precision guided system suitable for use in conventional aircraft launched bombs. The system includes a kit mounted upon the nose of the conventional bomb which replaces the conventional fuse disposed in a fuse well, the kit including guidance electronics controlling a self-contained jet reaction device and GPS P-code receiver electronics. The bombs are readied for discharge by signals broadcast from the aircraft into the bomb bay which transfer initial GPS data and commence operation of a gas generator which powers the jet reaction device.Type: GrantFiled: August 27, 1998Date of Patent: July 3, 2001Assignee: Lockhead Martin CorporationInventor: Joseph R. Mayersak

Patent number: 6237496Abstract: A tail fin assembly for a munition having a housing configured for attachment to the munition, at least one flight control surface, an actuator for effecting movement of the flight control surface(s), so as to facilitate guiding of the munition, and a guidance system for controlling the actuator mechanism. The guidance system has a global positioning system (GPS) receiver for effecting control of the actuator mechanism.Type: GrantFiled: June 3, 1999Date of Patent: May 29, 2001Assignee: Northrop Grumman CorporationInventor: Anthony Steven Abbott

Patent number: 6152041Abstract: A guided bomb is provided with a central hardback section having a pair of extensible wings pivotally attached thereto. The hardback section is attached to the bomb by a saddle member. After launch of the bomb from the aircraft, the wings are extended by means of an electric motor and gear train to provide the lift necessary for gliding flight. One or more ailerons are provided on the trailing edges of the wings to enable control of the flight, these ailerons being controlled by the bomb's resident guidance system. The geometry of the wings, the hardback section and saddle member are designed so that the guided bomb units can be fitted within a restricted space on bomber aircraft rotary launchers.Type: GrantFiled: November 23, 1998Date of Patent: November 28, 2000Assignee: Leigh Aerosystems CorporationInventors: Gordon L. Harris, Neil A. Levy

Patent number: 6144899Abstract: The recoverable airborne instrument platform accurately determines its present position and uses this data to execute a predetermined flight plan and ultimately guide its descent to a predetermined landing site. This is accomplished by installing the instrument package payload in the aerodynamic exterior housing of the recoverable airborne instrument platform, which has a plurality of moveable control surfaces thereon to autonomously control the altitude, attitude and flight path of the recoverable airborne instrument platform. A navigation circuit contained within the aerodynamic housing determines the geographic location of the recoverable airborne instrument platform as well as the location of at least one predetermined recovery site. The determined position data is used to dynamically calculate a flight path which allows the guidance control circuit to both execute a predetermined flight plan and controllably descend the recoverable instrument platform to a selected predetermined recovery site.Type: GrantFiled: October 4, 1999Date of Patent: November 7, 2000Assignee: University Corporation for Atmospheric ResearchInventors: Michael L. Babb, Michael William Douglas, Davis M. Egle, Kenneth Wayne Howard

Patent number: 5947419Abstract: An aerial cargo container system for transporting cargo from an aircraft to the ground having a cargo box with a continuous side wall with six rectangular side panels, and rotor blades having stowed positions against alternating box side panels and deployed positions extending outwardly from the box in a generally horizontal plane. Each blade may include a lower panel and an upper panel that has two triangular sections behind the leading edge that forms an aerodynamic camber. The blades are hinged to a rotor hub secured across the top of the box. The upward deployment of the blades is limited by tethers extending from the blades down to a tether attach frame secured across the bottom of the box. The box and blades are preferably formed of corrugated paper or plastic material. The entire unit rotates with the load to create aerodynamic braking and lower cargo to the ground with a minimum of energy being translated to the cargo on impact.Type: GrantFiled: January 21, 1998Date of Patent: September 7, 1999Inventors: Charles M. Warren, Charles V. Warren

Patent number: 5880396Abstract: Process for guiding an elongated missile, equipped with booster motor, sustainer, power source, control electronics, payload, and search head, from above, upon a target, such as a helicopter, where the missile, after ballistic flight, is braked before the target area by a drogue chute and is diverted into a position that is essentially perpendicular to the earth's surface over the target area so that the search head of the missile, which is suspended from the drogue chute, will be pointed downward, whereupon, after the search head has locked on the target, the drogue chute is separated and the missile is guided to the target by the sustainer, characterized in that, immediately prior to, before, or after the moment of drogue chute deployment, a lateral motor, located in the center of gravity of the missile, is turned on so that, first of all, in order to accelerate the tilt-off of the missile into the vertical, there is generated a force that is added vectorially to the force of gravity and that thereupon oneType: GrantFiled: March 26, 1993Date of Patent: March 9, 1999Inventor: Athanassios Zacharias
