Abstract
A delivery and release device for release and detonation of sequential explosive charges is disclosed to penetrate hardened structures. An aerodynamic shell is sized for delivery to a target by hand or mechanical means, including a first explosive charge is in a forward portion and a release device enclosing a second explosive charge is disposed in a shell rear portion. The release device includes a segmented cone positioned behind the first explosive charge, and a segmented cylindrical unit extending rearwards to enclose the second explosive charge within the shell during flight. Upon impact with the target, the first explosive charge detonates and directs high pressure gases against the target and deflection of gases rearwards against the segmented cone. The segmented cone and cylindrical unit are forced to separate and pivot outwards thereby releasing the second explosive charge for delayed delivery and detonation against the target leading to breach and destruction.
