Mechanism containing a parachute opening instant for illuminating mortar bombs

摘要

An instantaneous opening parachute containing device for illuminating mortar bombs comprises two or more cheeks (6,7) consisting of cylindrical segments which abut, by means of their outer surface, the shell (2) of the bomb and by means of the inner surface, the folded and packed parachute (5). A leaf spring (12) disposed in a preloaded condition in a seat (11) provided in the cheeks (6,7) stretches out after the ejection of the illuminating canister (3) from the bomb and draws mutually the cheeks (6,7) away. In order to enhance the drawing away effect, the cheeks (6,7) can be provided with holes (13) and bear a sheet (14) applied thereto consisting of a plastic or cloth film.
