A submunition delivery device including a master electronics module; a submunition module operatively connected to the master electronics module and including a plurality of submunition banks separated by bulkheads. Each of the submunition banks includes a plurality of submunitions; a base plug module operatively connected to the submunition module; and a distributed fuze module operatively connected to the master electronics module to limit a detrimental effect of the plurality of submunitions upon a collision by arming the plurality of submunitions before a dispense action.

Distributed fuze architecture for highly reliable submunitions

The present disclosure relates to systems and methods for explosive systems such as grenades with novel micro-electromechanical systems (MEMS) fuze and novel placement of the MEMS fuze providing increased performance, reliability, and safety. The MEMS fuze is disposed towards a rear portion of the explosive system providing superior performance and design flexibility. Further, the explosive system includes electronics configured to implement a launch timer and to sense impact or when the system stops spinning. The present invention includes an operational method improving safety and reliability by preventing detonation until after the launch timer expires, upon impact, or when the explosive system stops spinning.

Advanced grenade concept with novel placement of MEMS fuzing technology

A MEMS fuze having a moveable slider with a microdetonator at an end for positioning adjacent an initiator. A setback activated lock and a spin activated lock prevent movement of the slider until respective axial and centrifugal acceleration levels have been achieved. Once these acceleration levels are achieved, the slider is moved by a V-beam shaped actuator arrangement to position the microdetonator relative to a secondary lead to start an explosive train in a munitions round.

MEMS fuze assembly

An electrical generator includes a fluid-flow driven impeller including at least one impact arm; and at least one cantilevered beam disposed such that the impact arm strikes the cantilevered beam as the impeller rotates. The cantilevered beam at least partially includes a piezoelectric film.

Flow driven piezoelectric energy harvesting device

A rocket-launched line charge apparatus for obstacle breaching includes at least two explosive charges connected by detonating cord. The detonating cord passes through a flexible tubing, and is bunched in a sinuous arrangement within the plastic tubing so as to store excess detonating cord. The detonating cord is attached to the two ends of the flexible tubing by cable ties. The explosive charges, the tubing and the detonating cord are enclosed in a fabric sock formed by overbraiding, the fabric sock being the strength member connecting the two explosive charges during deployment. The plastic tubing arrangement is applicable to storage of other cords in other systems involving tethered deployment of objects.
