Ballistic Evaluation of Enhanced Energy LOVA Propellant in High Calibre Gun
This paper presents the data obtained on dynamic firing of a 2, 4 dinitro toluene (DNT) based Low Vulnerability Ammunition (LOVA) propellant using 120mm Fin Stabilized Armour Piercing Discarding Sabot (FSAPDS) kinetic energy ammunition. An optimized propellant composition was formulated using fine RDX as an energetic ingredient and a mix of cellulose acetate and nitrocellulose as binders. The propellant was statically evaluated by high pressure closed vessel (HPCV) evaluation technique by firings from 0.2 to 0.3g/cc in a 700 cc vessel. The propellant was characterized for vulnerability behaviour by testing for impact and friction sensitivity, ignition temperature and detonability behaviour. This indicates superior insensitivity behaviour as compared to the existing triple base composition. Dynamic firing of the propellant processed in heptatubular geometry was undertaken to assess the propellant charge mass. The achieved muzzle velocity (1662m/s) of this propellant is comparable to the standard NQ/M 119 a triple base propellant with a reduced charge mass (7.185kg) at a chamber pressure of 509MPa while meeting low vulnerability characteristics.
