Abstract

A grenade arrangement for forming a visual and infrared screening cloud, having a frangible body, a hollow cylindrical solid compact cohesive mass of compacted generally mutually adhered fine metal flakes of a copper composition, particularly brass, and of submicron thickness and multimicron in lateral dimensions, a cylindrical mass of HE explosive within such hollow cylindrical mass for aerosoling such metal flakes into the atmosphere, and having HE explosive percussisvely activating detonator means, a launch propulsion charge and pyrotechnic delay means between the propulsion charge and the HE explosive detonator.

Claims25

Dependent claims

A grenade arrangement for forming a visual and infrared screening cloud, comprising

a frangible elongate body,
a hollow elongate substantially solid compact cohesive mass of compacted generally mutually adhered fine metal flakes of a copper composition which may be burst apart under high explosive force, and being disposed within said body,
an elongate explosive mass of HE explosive disposed within and extending along the length of said hollow elongate mass,
detonator means for percussively effecting explosion of said elongate mass of HE explosive, and being carried by said body,
pyrotechnic time delay means carried by such body and operatively connecting with said detonator means for activation of said detonator means at a predetermined time after activation of said pyrotechnic time delay means,
and ignition means for said pyrotechnic time delay means.
