  • Patent number: 8933382
    Abstract: A missile guidance system is configured to estimate a time to go, the time to go comprising an amount of time until a missile would reach a closest point of approach to a target. The guidance system is also configured to estimate a zero-effort miss distance along a zero-effort miss vector, the zero-effort miss distance comprising a distance by which the missile would miss the target if the missile performs no future maneuvers. The guidance system is also configured to determine a tolerance for the zero-effort miss distance, the tolerance being a function of the time to go. The guidance system is further configured to modify a course of the missile by adjusting an expenditure of propellant such that the estimated zero-effort miss distance in excess of the tolerance is removed from future consideration.

  • Patent number: 8927915
    Abstract: Apparatus and a method for intercepting a rocket body during boost phase. A sensor is arranged to detect thermal emission in a range that is characteristic of a firing rocket body. The image detected by the sensor is applied to an analog-to-digital converter for digitization and application to a computer that includes a routine for separating the modulated photon energy of the detected image from the substantially unmodulated photon energy that characterizes rocket body emissions. The unmodulated photon energy, signature of the rocket body, may be utilized by a fire control system for tracking, targeting and aiming munitions at the firing rocket body.

  • Patent number: 8927914
    Abstract: An optical device forms a beam path between an optical end element at a beam path end and an object scene into which the beam path is directed via a field of view of the end element. The optical device contains an alignment device for pivoting the field of view relative to a predetermined direction, an end optical unit and an optical articulation for guiding the beam path from the pivoted field of view into the end optical unit. In order to achieve good shielding against spurious radiation, the device has a shielding unit containing a shielding element led partly around the optical articulation, which shielding unit shields the optical articulation against incident radiation that is not incident through the entrance or exit aperture of the optical articulation.

  • Patent number: 8921749
    Abstract: A perpendicular drive mechanism for a missile control actuation system employs an electric motor and power shaft operatively coupled to a first spur gear. A lead screw is coupled to a second spur gear. The lead screw is oriented parallel to the motor and perpendicular to a central longitudinal axis. The first and second spur gears meshingly engage such that the second spur gear rotates in the opposite direction as the first spur gear. A lead nut threadingly engages with and is configured to move linearly along the central axis of the lead screw. A crank arm is coupled on one end to the lead nut and on the other end to the canard shaft of a canard assembly. As the lead nut moves linearly along the central axis of the lead screw, the crank arm follows the lead nut and causes the canard assembly to actuate.

  • Publication number: 20140374533
    Abstract: A dual-mode, semi-active, laser-based and passive image-based seeker for projectiles, missiles, and other ordnance that persecute targets by detecting and tracking energy scattered from targets. The disclosed embodiments use a single digital imager having a single focal plane array sensor to sense data in both the image-based and laser-based modes of operation. A shuttering technique allows the relatively low frame-rate of the digital imager to detect, decode and localize in the imager's field-of-view a known pulse repetition frequency (PRF) from a known designator in the presence of ambient light and other confusing target designators, each having a different PRF.

  • Patent number: 8884202
    Abstract: A system and methods are provided for combining systems of an upper stage space launch vehicle for enhancing the operation of the space vehicle. Hydrogen and oxygen already on board as propellant for the upper stage rockets is also used for other upper stage functions to include propellant tank pressurization, attitude control, vehicle settling, and electrical requirements. Specifically, gases from the propellant tanks, instead of being dumped overboard, are used as fuel and oxidizer to power an internal combustion engine that produces mechanical power for driving other elements including a starter/generator for generation of electrical current, mechanical power for fluid pumps, and other uses. The exhaust gas from the internal combustion engine is also used directly in one or more vehicle settling thrusters. Accumulators which store the waste ullage gases are pressurized and provide pressurization control for the propellant tanks.

  • Patent number: 8816261
    Abstract: Control surfaces secured tangentially to a round projectile, such that the lift force generated by the control surfaces is generated through the projectiles centerline. This eliminates the need for an opposing fin to counter roll moment. Sizing the control surfaces to form an equilateral triangle gives each panel equal span, and enables the force generated by two panels to be equal and opposite to that of the opposing panel. The end effect is that each panel only has two active states (neutral and positive deflection). Thus, a solenoid and a return spring may be used to control the canards. Additionally, the control panels may fold along the surface of the projectile, which frees up internal volume and minimizes the length of the control section.
