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.

Grenade fumigène à main à dégagement rapide comprenant une tête d'allumage (A) commandée manuellement et un élément de masse active (B), dans laquelle le percuteur situé sur la tête d'allumage pour déclencher la chaîne d'activité pyrotechnique est chargé au moyen d'une goupille de sûreté pour la sécurité de manutention,le moyen fumigène situé dans l'élément de masse active est constitué de minces feuilles (flocons) combustibles en forme de disques ou secteurs de disques enduits d'un agent fumigène à base de phophore rouge qui remplissent pratiquement le contenant de l'élément de masse active autour d'une capsule pour l'unité d'allumage/ éclatement qui s'y trouve, les composants lourds de cette grenade fumigène à main à dégagement rapide sont maintenus ensemble par des fixations qui sont stables quand elle éclate, et les composants essentiels de la grenade sont de préférence à base d'aluminium. Dans une version préférée, la charge d'allumage/ éclatement est constituée d'une charge détonante classique de perchlorate d'aluminium et de potassium de manière à minimiser les gaz de combustion produits quand elle réagit.
