  • Patent number: 6920826
    Abstract: An energy supply device for a mortar fuse includes a housing, a driven rotary shaft including a cylindrical shaft surface rotatably disposed in a stationary cylindrical bearing surface in the housing, and a fan connected to the shaft for rotating the shaft in a single direction of rotation in a speed range of 30,000-50,000 rpm. Either of the cylindrical bearing surface or the cylindrical shaft surface has a destructible coating of polytetrafluoroethylene, the coating having a thickness in the range of 0.02-0.03 mm, and being destructible in response to rotation of the shaft in the speed range for a period of time no longer than 5 minutes.

  • Patent number: 6845714
    Abstract: On-Board Power Generation System for a Guided Projectile eliminates the need for batteries as a power source to power the guiding mechanism residing inside the projectile. Instead, an electrical generator and a wind-driven turbine to drive the generator are utilized to produce power. In this way, a small portion of the projectile's kinetic energy is converted into electrical energy. The power thusly produced is, then, coupled to the guiding means. The projectile is appropriately configured to accommodate therein the power generaion system and air inlets and exhaust ports that are necessary to enable the system to operate.

  • Patent number: 6564716
    Abstract: A fuze for a munition adapted to prevent unintended arming thereof. The fuze incorporates an arming screw having a keyed portion and a centrifugal locking mechanism for preventing rotation of the arming screw unless the fuze mechanism is in a rapidly spinning condition such as that experienced when the fuze and its associated munition are deployed from an airborne rocket or artillery shell, and thus spinning at a rate of at least several thousand rpm. The centrifugal locking mechanism includes a pair of locking members which are biased by biasing elements into engagement with the keyed portion of the arming screw. This prevents the arming screw from being accidentally unscrewed from an inertia weight within the fuze, thus placing the fuze in an unintended armed condition.

  • Patent number: 6481354
    Abstract: A mortar fuse includes a fan wheel rotated in response to motion of the mortar fuse after the mortar has been launched. The fan wheel rotates a helix on which an activation wheel is mounted. The activation wheel moves in a path along the axis of the helix in response to rotation of the helix and eventually impacts against, and pierces, an acid container. Battery acid flows from the container and into battery cells, to energize the battery. The activation wheel includes a magnetic material. A coil is disposed along the path of travel of the activation wheel so that electric energy is generated in the coil as the magnetic activation wheel moves therepast. The electric energy operates a counter which controls a time function of the mortar fuse.

  • Patent number: 5115742
    Abstract: An integrated and mechanically aided warhead afterbody arming device for siles using mechanical rotation of the missile to arm the warhead is disclosed. A self-contained electrical generation system provides electrical power for the proper arming of the warhead. Mechanical rotation energy is used to generate electrical power for warhead arming. Revolution counters and mechanical detents are used to prevent premature arming.

  • Patent number: 4969396
    Abstract: An arming arrangement with rotatable airfoils or blades of a propeller constituting the deliverants for an arming criterium. The blades of the driving propeller for a drone, have the rotational movement thereof determined from the tail end of the drone towards one side of the propeller hub through a beam or radiation coupling and is then conducted to a counting evaluating circuit for the derivation of a release signal for the arming device.
