摘要： Shock resistant mounting structures for fuze systems. The shock resistant mounting structures may comprise: a shock resistant base cap and a shock resistant washer. The shock resistant base cap may comprise a circular cap housing and a plurality of first cripple studs disposed within the circular cap housing. The circular cap housing may be configured to engage a flange end of a fuze and may be adapted to snugly fit within a fuze well. The shock resistant washer may comprise a ring-shaped housing and one or more second cripple studs radially disposed within the ring-shaped housing. The ring-shaped housing may have a center opening adapted to engage a fuze body. When installed, the shock resistant base cap and shock resistant washer may be disposed within the fuze well and may minimize or divert shock loading energy from entering a fuze.

摘要： A guiding kit for guiding a projectile to a target comprises a front part and a rear part. The front part and the rear part are rotatably connected to each other to enable relative rotation about a common central longitudinal axis of rotation. The front part comprises a front transceiver (T/X) unit that is disposed next to the rear end of the front part and coinciding with the longitudinal central axis of rotation and adapted to transmit signals towards the rear part. A rear transceiver unit is disposed against the front transceiver unit and adapted to communicate with front transceiver unit when the front part and the rear part are rotating with respect to each other.

摘要： Embodiments of the invention are directed to enhancing insensitive munitions performance. Some embodiments of the invention employ an outgassing pad having unique geometrical configurations and positioning. Other embodiments rely on using thermally-releasable components to foster billet expulsion. Additional embodiments combine both aspects into an entire cook-off mitigation system.

摘要： Aspects of the disclosure relate to terminating flight of a balloon that may include separating a connection between a balloon envelope and a payload of the balloon. In one example, a payload separation apparatus includes a first shaft configured to attach to the envelope, a second shaft configured to attach to the payload, a pair of arms, and a bracket arranged to secure the pair of arms to the first shaft. In another example, a system includes a flight termination assembly having a cutting edge configured to cut an opening in the envelope and a payload separation apparatus. The apparatus includes a first shaft configured to attach to the envelope, a second shaft configured to attach to the payload, a pair of arms, and a bracket configured to secure the pair of arms to the first shaft. The system also includes a controller configured to activate the cutting edge.

摘要： A stun grenade includes a fuze assembly secured to a housing adjacent gas outlet ports. The fuze assembly includes a fuze body having contact surfaces located in the flow path of the gas from the outlet ports so that gas flowing from the outlet ports impinges on the contact surfaces. The contact surfaces of the fuze body extend at an angle of no more than about 50 degrees to the first direction.

摘要： An explosive matrix assembly of the present disclosure has a single detonating cord formed into a grid, and the grid has a first plurality of detonating cord portions lying in a first plane and a second plurality of detonating cord portions lying in a second plane and the first plurality of detonating cord portions perpendicularly overlay the second plurality of detonating portions, wherein the overlay creates a plurality of crossings between the first plurality of detonating cord portions and the second plurality of detonating cord portions. Additionally, the explosive matrix assembly has one or more point explosives coupled to the crossings for initiation of an explosion.

摘要： An initiator assembly that includes an initiator and a containment shell. The initiator has an initiator housing, an initiator device mounted inside the initiator housing, and an input charge that is formed of an energetic material. The initiator device is configured to initiate at least one of a combustion event, a deflagration event and a detonation event in the input charge. The containment shell is coupled to the initiator housing and defines a space into which gas and/or particles are ejected from the initiator housing if the initiator device is not activated and the input charge is cooked off.
