Title: Sean Mulvihill: Innovator in Projectile Technology

Introduction

Sean Mulvihill is a notable inventor based in Lake Hiawatha, NJ (US). He has made significant contributions to the field of projectile technology, holding 2 patents that showcase his innovative approach to enhancing the performance and accuracy of projectiles.

Latest Patents

One of his latest patents is the "Piston actuated extended range projectile with segmented slip band." This invention delivers a pellet payload to an increased range with enhanced accuracy. The design features a two-piece aerodynamically stable pusher, consisting of a body and tailpiece, which fits into a standard 40 mm cartridge case using three sabots. To effectively seal against combustion gases, a three-piece split rotating band is employed.

Another significant patent is the "Pyrotechnic delayed extended range shotgun munition." This invention also utilizes a two-piece aerodynamic pusher, which fits into a standard 40 mm cartridge case by means of three sabots. Once the cartridge case is functioned, combustion gases propel the projectile forward and ignite a delay column located in the rear of the pusher. Upon exiting the muzzle, the sabots are discarded, allowing the pusher to continue downrange as the delay column burns. After the delay has elapsed, a charge in the pusher body is ignited, releasing the payload as the cap pops off and the pellets are dispersed. This innovation effectively moves the payload release point from the muzzle to a designated point downrange based on the delay length.
