HAND GRENADE Russian patent published in 2014 - IPC F42B27/00 F42C14/02 F42C19/00 

FIELD: weapons and ammunition.

SUBSTANCE: hand grenade includes fuse with fuse actuator element. The fuse includes at least six microelectromechanical structures. The structures consist of coaxial series of silicon crystal with cantilever needle formed inside, silicon crystal with doped hydrogen and solid oxidant with 50 mcm thick porous layer are, heat-conducting monocrystalline silicon crystal, and silicon crystal with porous layer area of at least 60 mcm thickness, mounted on a glass substrate. The substrate features a hole in the central part. Heat conductivity rate of heat-conducting element is higher than heat conductivity rate of silicon crystal with porous layer area of at least 60 mcm thickness. Microelectromechanical structures are mounted on revolver drum and attached in a frame. The frame is built in a case with vacuum inside. Fuse actuator element includes button with needle, coaxial to cantilever needle and connected to fuse axis by a nut.

EFFECT: increased specific volume of brisant explosive in a standard grenade.
