Abstract
FOR TACTICAL WEAPONS SUCH AS ANTITANK ROCKETS, IT IS IMPERATIVE THAT THE BOOST PHASE OF FLIGHT BE AS SHORT AS POSSIBLE TO MAKE A KINETIC ENERGY WEAPON EFFECTIVE AGAINST NEARBY TANKS. HIGH BOOST ACCELERATION STRESSES ROCKET PROPELLANT GRAINS TO FAILURE BY CRACKING AND SEPARATION FROM THE CHAMBER WALLS. PROPELLANT STRESSES LIMIT MAXIMUM ACCELERATION. CONVENTIONAL ROCKETS ARE STRESS LIMITED TO MAXIMUM ACCELERATIONS \500 G AND MINIMUM BURN TIMES \0.5 SECONDS. SPARTA PROPOSES A NOVEL DESIGN THAT CAN ACCELERATE AT LEVELS GREATER THAN 20,000 G AND THAT HAVE BURN TIMES LESS THAN 10 MILLISECONDS. THE SPARTA SOLUTION TO THE DESIGN OF HIGH ACCELERATION VERY SHORT BURN TIME ROCKETS IS TO USE AVAILABLE FULLY DEVELOPED GRANDULAR GUN PROPELLANT AND CHANGE THE BASIC DESIGN OF THE ROCKET MOTOR. GRANDULAR GUN PROPELLANTS WOULD BE LOADED INTO A ROCKET MOTOR CASE WITH AN INTEGRAL SUBMERGED NOZZLE WHOSE ENTRANCE IS NEAR THE TOP OF THE MOTOR DOME. ACCELERATION INDUCED INERTIA FORCES WOULD KEEP THE PROPELLANT WITHIN THE MOTOR CAVITY AND ONLY GASES WOULD EXIT THROUGH THE NOZZLE. BY THIS MEANS, IT IS POSSIBLE TO ACHIEVE 6000 FPS IN \10 MILLSECONDS AT A RANGE OF APPROXIMATELY 30 FEET.
