Abstract

A multi-petal adapter that enables projectiles of different sizes to be used in a single dearmer. The adapter includes a plurality of petals that are secured, in a detachable way, to a base. The main function of the base is to secure the petals until the projectile is fired from the dearmer. Whereupon, the adapter will start petalling until the petals become detached from the base, so that the adapter imparts minimal or no energy or damage to the intended target. The adapter fully regulates the energy imparted to the various projectiles, by allowing propellant gases to bleed through channels that are formed between the petals. As a result, the present adapter fully supports a proper projectile launch and ensures its proper orientation toward the target.
