The poorly ignited charge moved the projectile partially down the tube, increasing the surface area of the propellant. The increased surface area of the propellant then ignited in the tube, raising pressures in parts of the gun not designed for them. The large overpressure caused "catastrophic tube failure" (an explosion destroying the gun tube ...

The self-igniting storeable liquid bi-propellants have somewhat lower specific impulse than LOX/kerosene but have higher density so a greater mass of propellant can be placed in the same sized tanks. Gasoline was replaced by different hydrocarbon fuels, [7] for example RP-1 – a highly refined grade of kerosene. This combination is quite ...

A mixture of 63% hydrazine, 32% hydrazine nitrate and 5% water is a standard propellant for experimental bulk-loaded liquid propellant artillery. The propellant mixture above is one of the most predictable and stable, with a flat pressure profile during firing. Misfires are usually caused by inadequate ignition.
