Abstract: A shock bump (10) comprising a diverging nose (20) and a converging tail. The tail has at least one plan-form contour line with a pair of concave opposite sides (22, 23). The shock bump provides an improved shape with relatively low drag. Furthermore, the concave shape of the tail tends to promote the development of longitudinal vortices which can reduce shock induced buffet at certain operating conditions.

Abstract: A rotating launcher system includes a plurality of rocket or missile housing tubes arranged in a circular pattern within a carousel, a set of frames, a cylindrical protective skin, an aerodynamically optimized nose cone with a bore, and an optional door covering the bore, enabling rockets or missiles to exit the launcher. The rotating launcher system may also include an aerodynamically optimized tail cone with a bore, and an optional door covering the bore, enabling exhaust from the rockets or missiles to exit the launcher. The rotating launcher system also includes an integral controller for an indexing motor, and an indexing motor enabling the bores of the nose and tail cones to align with different rockets or missiles in the carousel by either rotating the nose and tail cones, or by rotating the carousel.

Abstract: Improvements in a torque limiter that uses a plurality of ball bearings that are retained in a cage. The ball bearings are compressed to create frictional drag on opposing flat plate surfaces. In some military vehicles the gun turret is rotated by personnel turning a crank that rotates the turret. The crank rotates a pinion or chain that turns the rack of the turret. When the turret does not move freely the personnel will typically apply more force that results in damaging the pinion, chain and or the rack. The torque limiter for a gun turret in this application connects between the crank and the drive train to allow the crank to turn without applying excessive torque forces on the pinion, chain and or the rack.

Abstract: A firearm with a tilting barrel (1) with the possibility of setting a change of the tilting direction of the barrel (1) containing a breech block (5) for securing the barrel, the breach block containing on a part of its perimeter a locking surface (11) for securing the firearm against its tilting in the direction opposite the locking surface (11). The locking surface can be rotated around the longitudinal axis of the breech block (5) for setting the change of the tilting direction of the barrel (1).

Abstract: A remotely operable machine gun charger is provided for selectively controlling the forward-to-rear movement of a machine gun bolt pin. When the bolt pin is released from its safe position the charger permits the bolt pin to be spring-driven back to its armed position substantially instantaneously by the bolt spring without waiting for pin engagement and drive structure portions of the gun to be returned to their forwardmost positions. The charger permits the gun to be fired during such movement of the engagement and drive structure back to their forwardmost positions, and the charger may be mounted on and removed from the machine gun without the use of tools, or the necessity of removing or adjusting any of the internal components of the machine gun.

Abstract: The foldable ramp is intended to store, carry and launch relatively large size tube-launched missiles typically on board of relatively small sized naval surface ships. Accordingly, the foldable ramp comprises a frame suitable for carrying one or more canisters for launching rockets or missiles and support elements, which are pivotably attached to the frame and which are adapted to pivotably connect to the launching platform so as to allow rotary movement of the frame with respect to the launching platform. A lifting device lifts the front end of the frame whereby the rear end of the canisters displace a horizontal distance towards the rear of the ramp as said lifting device lifts the frame. Adverse effects of the aft flame of the launched rocket or missile is securely displaced to the outside of the vehicle while foldability of the ramp enables to prevent or reduce radar and eye visibility of the launcher, particularly when mounted on a naval surface ship.

Abstract: A two-piece adapter for mounting a guidance system on unguided rockets allows for the existing designs and stores of unguided rockets to be retrofitted with guidance capability to provide a “guided rocket”. The adapter provides the external mounting features for mounting the guidance system and does so in a manner that transfers the steering loads of the guidance system to the rocket airframe and maintains the proper preloading and relationship of the fuze-to-warhead to detonate the warhead. The two-piece adapter comprises an inner adapter and an outer adapter. The inner adapter is secured between the fuze and warhead without requiring modifications of either part and provides the external mounting feature. The outer adapter is secured to the inner adapter and effectively moves the external mounting feature forward in front of the fuze where the guidance system is attached.
