Title: Frank H. Bell: Innovator in Propellant Technology
Introduction
Frank H. Bell, based in Logan, Utah, is a prominent inventor with an impressive portfolio of 23 patents to his name. His work has significantly impacted the field of propellant technology, showcasing innovations that enhance the performance and safety of various ammunition types.
Latest Patents
Two of Frank H. Bell's latest patents highlight his innovative approach to propellant development. The first pertains to a method of preparing a non-feathering nitramine propellant. This low vulnerability ammunition (LOVA) propellant utilizes a polyurethane binder combined with a mixture of nitramines that predominantly includes RDX and at least 7.5 wt. % HMX. This specific formulation enhances the precure extrudability of the propellant grain. The polymerization process ensures extrudability without slumping prior to complete cure, achieved by maintaining a NCO:DIOL:TRIOL equivalent ratio of approximately 110:15:85.
The second patent describes a double-path detonation tube inertia igniter. In this innovative design, a chisel point striker is held in place by a shear pin, positioned on the center line of a warhead above a flash tube filled with a percussion-sensitive priming mixture. Upon impact with a resistant target, the shear pin shears, allowing the striker to violently impact the target and detonate the priming mixture. This detonation creates a blast wave that travels through two distinct paths, activating separate detonation wave acceptors or boosters, which then communicate the detonation reaction to the main explosive charge of the warhead.
