Abstract

1. An increased-range artillery projectile of any caliber, of the type which comprises at its base (4) a combustion chamber (4a) prolonged by one or more nozzles (12), a pyrotechnic charge (13) generating a base drag reduction, and a charge (14) generating an additional propulsion, characterized in that both charges (13, 14) are integrated into the combustion chamber (4a) and blended at the location of their mating surfaces so as to form a cast cylindrical propellant grain (6) arranged with or without a central channel (9) the composition (13) with a slow burning rate on the order of 0.7 to 2 mm/s under a pressure of 10**5 Pa being primed upon projectile launch in order to initiate at the end of combustion the composition (14) with a quick burning rate on the order of 5 to 20 mm/s under a pressure of 10**6 Pa.
