Abstract

A rapid-release smoke hand grenade comprising a manually actuatable igniter head (A) and an active mass member (B), wherein the striker located on the igniter head to initiate the chain of pyrotechnical activity is loaded by means of a safety clip so as to be safe to handle, the smoke-forming means located in the active mass member is in the form of combustible disc-shaped or disc sector-shaped thin leaves (flares) coated with smoke-forming agent based on red phosphorus which practically fill the canister of the active mass member around a capsule for the ignition/bursting unit located therein, the heavy components of this rapid-release smoke hand grenade are held together by connecting elements which are stable when it bursts, and the essential components of the grenade preferably consist of aluminium. In a likewise preferred embodiment the ignition/bursting charge of the ignition/bursting unit consists of a classical detonating charge of aluminium and potassium perchlorate in order to minimise the combustion gases evolved when it reacts.
