Abstract
An improved smoke canister 1 has a high-pressure proof propellant chamber 20 containing a propellant charge 21, consisting of a reduced-smoke generating powder, which can be ignited electrically by an ignition charge 19. Capillary bores 20b and 20c are provided respectively in both end faces of the propellant chamber 20. When a smoke canister 1 is fired, propellant gases under high pressure exit via the capillary bore 20b into the launcher (not shown), and contribute to the uniform acceleration of the smoke canister 1. This makes it possible to launch heavier smoke canisters. The smoke-generating charge 12 is ignited by means of the second capillary bore 20c.
Claims11
A smoke canister, comprising:
- a casing;
- a smoke-generating charge in the casing;
- a lid attached to the casing, the lid having a periphery;
- electrical contact rings on the periphery of the lid;
- a container having first and second end faces and having a high-pressure proof propellant chamber between the end faces, the container being mounted in the lid with the first end face oriented toward the smoke-generating charge, the first end face having a first capillary bore, the second end face having a single second capillary bore, the diameter of the second capillary bore ranging from about 1 mm to about 1.4 mm;
- a propellant charge in the propellant chamber;
- and
- an ignition charge in the propellant chamber, the ignition charge being electrically connected to the contact rings.
