Title: The Innovations of Bertrand Padiolleau

Introduction

Bertrand Padiolleau is a notable inventor based in Bourges, France. He has made significant contributions to the field of munitions, holding two patents that showcase his innovative approach to explosive devices. His work is primarily associated with Nexter Munitions, a company known for its advanced defense technologies.

Latest Patents

One of Padiolleau's latest patents is for a shaped charge. This invention includes an explosive load positioned in a casing, a liner applied on the load, and means ensuring the securing of the casing and the load bearing the liner. The securing means consist of a ring with a stop surface for the liner and at least two shims that cover an angular sector and move radially through the action of a tightening means. This design allows the shims to be pressed against an inner bearing surface of the casing. Notably, the tapped hole of the tightening screw(s) has its axis parallel to the casing's axis, and the shim is positioned axially relative to the ring by at least one radial pin, allowing for sliding.

Another significant patent by Padiolleau is a safety and arming device for a spin-stabilized explosive projectile. This device incorporates a screen that obstructs a transmission channel linking a detonator and a pyrotechnic relay. The screen consists of two half-screens that can move with respect to one another and transversally with respect to the channel. When the two half-screens contact one another, they obstruct the channel. These half-screens can slide in a bore hole carried by a rotor that is coaxial to the projectile. The rotor can pivot on the projectile's axis and carries the channel. The half-screens are locked into the obstructing position by at least two locks, including an inertial lock that retracts when the projectile is fired and a centrifugal lock formed by a spiral spring surrounding the rotor's external cylindrical surface.
