An electronics ordnance delivery system that has an electronics component encased within a potting material, which itself is within a housing exoskeleton. A deceleration sleeve receives the exoskeleton, and is designed to shear away during a bullet's entry into a target body such that the electronics component is successfully deployed and remains in the target even if a part of the bullet exits the target. The system also includes an outer jacket that is also designed to shear away. The system can include a core that assists in the deployment of the electronics ordnance within the target.

A method for modifying a separable projectile between a test embodiment or an effect embodiment includes detaching the front projectile body from the rear projectile body, arranging a payload container in the front projectile body where the payload container comprises measuring equipment or an effect part, and fitting the front projectile body to the rear projectile body by way of a belt. A separable projectile which can be modified between a test embodiment and an effect embodiment is also provided.

A projectile is disclosed, comprising: a body; a fin having a magnet disposed thereon, the fin being coupled to the body, at least a portion of the fin being arranged to: (i) stay inside the body before the projectile is launched, and (ii) exit the body after the projectile is launched; a magnetic sensor disposed within the body, the magnetic sensor being arranged to detect changes in a position of the magnet relative to the magnetic sensor while the fin is exiting the body; and a data recorder disposed within the body, the data recorder being operatively coupled to the magnetic sensor, wherein the data recorder is configured to use the magnetic sensor to collect data indicating a displacement of the fin relative to the body after the projectile is launched.

Systems according to the present disclosure provide one or more surfaces that function as power radiating surfaces for which at least a portion of the radiating surface includes or is composed of fractal cells placed sufficiently closed close together to one another so that a surface wave causes near replication of current present in one fractal cell in an adjacent fractal cell. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges. Fractal plasmonic surface cards are described.

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.

The system and method for accurately determining range-to-go for a time-delayed command detonation of a projectile. Using dual laser and/or radio frequency detectors on the tail and on the nose of a spinning projectile to determine the range-to-go, time-to-go, and/or lateral offset from the projectile to the target. A time to detonation clock is used to determine when a projectile transitions from an exterior to an interior of a structure such that the projectile can more accurately detonate within a fixed structure.

Provided is a non-motorized flying unit. The non-motorized flying unit includes a body part having a head part and a tail part having an accommodation space and a through hole, an image capturing unit installed in the through hole and configured to obtain an image information, a protective window installed in the through hole, a plurality of shock absorbing devices installed at the end portion of the tail part, a weight installed at the end portion of the tail part, and a lighting device installed at an end portion of the plurality of shock absorbing devices. A propulsion unit which is detachably coupled to the tail part storing a propellant which, upon combustion, forms pressure in the propulsion unit to provide thrust to the body part.

A wireless detonator (10) includes a detonation side receiving antenna (11), a detonation side transmitting antenna (18), an initiator (14) and a detonation side electronic circuit. The detonation side receiving antenna (11) receives energy for driving the detonation side electronic circuit, a control signal and an initiation signal. The detonation side electronic circuit receives the energy, the control signal and the initiation signal via the detonation side receiving antenna (11), transmits a response signal via the detonation side transmitting antenna (18) and ignites the initiator (14) in accordance with the initiation signal. A response frequency of the response signal is set to be greater than or equal to 100 MHz and less than or equal to 1 GHz.
