In a number of cases inertial forces applied to a burning substance significantly increase the burning rate. In the present study the burning of aluminized systems is studied experimentally and theoretically. Measured were the combustion rate, mass, and composition of slags forming in a condensed system consisting of 70 ammonium perchlorate, 15 rubber, and 15 aluminum powder with a particle dimension size of about 10 micrometers. For the purpose of creating the overloads the specimen was attached radially to a disc radius 4.5 cm, which together with the electrical motor which rotated it was placed in a vessel with a volume of 2 which was filled with nitrogen when the disc reached a constant rate of rotation, an electrical igniter was used to ignite the specimen.
