  • Patent number: 9470498
    Abstract: A pressure switch is provided to arm a munition's fuze mechanism upon launch. The switch operation is based upon extreme gas pressures experienced during launch of the munition. The switch includes a piston contained in a housing. The piston translates due to launch pressures. The piston translation then causes a copper puck component to contact nearby electrical stab pins, to close a circuit. The closed circuit is then used to electrically arm the fuze mechanism.

  • Patent number: 9441928
    Abstract: A method of autonomously tailoring a detonation delay time of a gun launched munition by utilizing target impact signatures including but not limited to a MOUT target set; earth and timber bunker, triple brick wall, double reinforced concrete, and light armor. While the present method is applicable to countless munition configurations, the projectile architecture used to develop the discrimination algorithm includes a tandem warhead configuration. Upon target impact the forward warhead detonates and pre-damages the target to allow the rear warhead to break through. Target impact data is used to set a detonation delay in the rear warhead providing increased performance behind the target.

  • Patent number: 9317477
    Abstract: A computer program product corrects a detonation time from a ballistic table, based on the actual velocity of a projectile measured upon exit of the projectile from the gun tube. The computer program product transfers a 16-bit data stream, through a 16-bit to an 8-bit encoder, to a fuze controller implemented as an 8-bit platform, to provide precise timing adjustment to a fuze controller. The computer program product significantly improves the accuracy of detonation times for air burst mode. The encoder calculates the absolute truncated, square rooted, X, of the input time delay number, as well as the error correction number, Y. The encoder then transmits both numbers X and Y as an 8-bit data stream, optionally along with the parity data to the fuze controller.

  • Patent number: 9021960
    Abstract: An isolated, coaxial, high pressure feed-through fitting provides two electrical paths through a barrier. The fitting includes an outer dielectric disposed in an opening in the barrier. A conductive housing with a central through bore is disposed in the outer dielectric. An inner dielectric is disposed in the through bore in the conductive housing. A central conductor is disposed in the inner dielectric. One electrical path includes the central conductor and another electrical path includes the conductive housing. Flanged portions on the conductive housing and the central conductor bear on flanged portions of the outer dielectric and the inner dielectric, respectively, to create a high pressure seal.

  • Patent number: 8433460
    Abstract: An onboard sensor suite generally includes two main components: a proximity sensor suite for measuring the projectile muzzle velocity; and a pressure sensor suite for measuring the projectile airspeed. The flight velocity of the projectile can then be estimated with a high degree of accuracy using either the muzzle velocity by itself or the airspeed by itself, or, in a preferred embodiment, by using both the muzzle velocity and the airspeed. The proximity sensor suite includes proximity sensors that are mounted along a projectile body; a wire harness; and an onboard computer or CPU. The pressure sensor suite includes a Pitot pressure transducer and two static pressure transducers that are mounted within the projectile body; a wire harness; and a CPU.
