A mounting system for mounting an electronic component (2) in a housing (8) comprises a visco-elastic damping element (14, 20) for damping the transmission of vibration from the housing (8) to the component (2) in use, and a support (24, 52) for supporting the component (2) in the housing (8) independently of the damping element (14, 20) whereby the weight of the component (2) is substantially or completely removed from the damping element (14, 20). The support (24, 52) is configured to be selectively releasable from the component (2) such that the component (2) is then supported only by the damping element (14, 20).

Disclosed are ammunition and ammunition tracking systems. The ammunition and ammunition tracking system may include a first projectile and a marker. The marker may be associated with the first projectile. The marker may contain a unique signature such that the first projectile may be identifiable from a second projectile.

An inverted F antenna for use in a projectile includes a ground plane and a radiating element oriented orthogonal to the ground plane and centered on the ground plane. The radiating element includes a ground stub trace having a relatively thick width, a meandering trace with a vertical orientation and a relatively high ground clearance and a feed trace having a tapered head.

A non-lethal, non-impact smart projectile fired from a suitable launcher and equipped with a digital camera, CPU microprocessor and computer vision programming that can recognize a designated target and track a moving target, while moving at high speed. An image dataset of the target stored in memory of the CPU that enables the projectile to recognize a human or small UAV drone in real time within fractions of a second. A steering and braking system comprising several fins/air brakes, controlled by the CPU and MEMS micro-actuators, that enable the projectile to track a moving target or slow the projectile down. A projectile equipped with actuators that dispenses a non-lethal, non-impact payload or payloads as the projectile approaches the target.

The present invention provides an ammunition cartridge having a primer insert having a top surface opposite a bottom surface and a extraction flange that extends circumferentially about an outer edge of the top surface; a coupling element that extends from the bottom surface, wherein the substantially cylindrical coupling element is adapted to receive a polymer overmolding; a primer recess in the top surface that extends toward the bottom surface, wherein the primer recess comprises a recess bottom and a circular recess side wall; a primer flash aperture through the recess bottom that extends through the bottom surface, wherein the primer flash aperture is adapted to receive a polymer overmolding to form a flash hole; and a groove in the primer recess positioned around the primer flash aperture adapted to receive a polymer overmolding, wherein the groove extends at least partially over the bottom surface and at least partially over the circular recess side wall and the groove is adapted to receive polymer over the bottom surface and at least partially over the circular recess side wall.

The invention relates to recoilless firearms, the gun carriage of which has zero recoil during a shot. The recoilless firearm comprising a gun carriage, a fire control tool, and a barrel, which contains at least a breechblock, a primer-igniter, a propellant charge and a projectile, wherein the barrel is connected to the gun carriage with the possibility of movement in the gun carriage during a shot under the impact of the propellant gas on the breechblock. The barrel is provided with a possibility of disconnecting from the gun carriage before the shot. The fire control tool is connected to the barrel and provides the barrel displacing in the gun carriage for carrying out the shot, and the breechblock is equipped with a firing mechanism, which acts on the primer-igniter when the barrel is displaced in the gun carriage. The invention provides safety of a shot via the guaranteed elimination of recoil during a shot, and also increases the efficacy of neutralizing large targets due to the applicability of high-impulse ammunition when shooting under the water, shooting from the air into the water, shooting in the air and also in weightlessness in the open space.

A ball joint gimbal (BJG) seeker assembly is provided and includes a back shell, a retaining system disposed to urge the seeker ball toward the back shell and a piezoelectric ultrasonic motor and sensor system arrayed between the seeker ball and the back shell. The piezoelectric ultrasonic motor and sensor system is pre-loaded by the retaining system and configured to controllably drive an angular orientation of the seeker ball.

A projectile has a liner forming an interior void, and a core disposed in a first region of the void proximal to a trailing end portion of the liner, with a portion of the void disposed forward with respect to the core. An outer jacket covers a leading end portion of the liner to enclose the interior void. When the projectile impacts a target object, the core travels in a direction of flight through the leading end portion of the liner to impact the object. When the projectile impacts a target surface at a non-zero angle of approach with respect to the normal of the target surface, the projectile creates a deformation in the target surface immediately before the core travels through the leading end portion of the liner to impact the target. This deformation reduces the probability that the core will ricochet off the deformed portion of the surface.

Embodiments of a projectile are disclosed herein. According to various embodiments, a projectile includes a substantially solid core of a material, and two or more petals attached to the core. The two or more petals can be formed from the same material used to form the core and can include a trocar tip. A cavity can be bound by the core and inner surfaces of the plurality of petals.

A projectile having a projectile body that includes a front end and a rear end. A cavity in the rear end of the projectile body. An internal core in the cavity. The internal core including a front end and a rear end. The front end of the internal core inserted towards the front end of the projectile body.
