【 摘 要 】

'This paper presents the data obrained ondynamic firing of a cellulose acetate binder-based low vulnerabilityammunition (LOV A) propellant using 120 mm fin-stabilised armourpiercing discarding sabot (FSAPDS) kinetic energyammunition. Anoptimised propellant composition formulated ~sing fine RDX as anenergetic ingredient and a mixture of cellulose acetate andnitrocellulose as binder was qualified fit for firing in a high calibregun by its successful static evaluation for absolute ballistics usinghigh pressure closed vessel technique. Dynamic firing of the propellantprocessed in heptatubular geometry was undertaken to assess thepropellant charge mass. This propellant achieved higher muzzle velocityas compared to the standard NQ/M119 triple-base propellant while meetingthe non-vulnerability characteristics convincingly.
