US12276488 - Multi-compartment mortar increment container

A multi-compartment mortar increment container (MIC) enables burning of two propellants to broaden the pressure-time curve providing additional energy and force behind a mortar shell while maintaining allowable pressures. During the ballistic cycle, the mortar increment container burns allowing the faster propellant to mix with the slower propellant. The slower propellant will burn later in the ballistic cycle generating higher pressure behind the projectile leading to higher velocity.

The multi-compartment mortar increment container allows for the simultaneous burning of two propellants with different burn rates, enhancing the pressure-time curve for increased energy and force behind a mortar shell. This design enables the slower propellant to ignite later in the ballistic cycle, resulting in higher pressure and velocity for the projectile.

Claim 1

A multi-compartment mortar increment container comprising: a housing assembly; and a divider within the housing wherein the divider defines a first compartment for housing a first propellant and a second compartment for housing a second propellant and wherein the first propellant and the second propellant have different burn rates. a housing assembly; and a divider within the housing wherein the divider defines a first compartment for housing a first propellant and a second compartment for housing a second propellant and wherein the first propellant and the second propellant have different burn rates.
