Abstract
A promising direction in barrel ballistics to increase the muzzle velocity of a projectile is the use of new fuels as an attached charge. The paper presents an experimental and theoretical method for determining the law of fuel combustion in a manometric experiment (in a closed volume), which allows, by a small number of experiments, to determine the change in the law of combustion as the fuel burns and depending on pressure. The technique is demonstrated on the example of processing three experiments with model high-density fuel. The obtained laws of combustion of high-density fuels can later be used to calculate the gas-dynamic parameters of a shot from a barrel system or a nozzle bomb (in a semi-closed volume) using these fuels.
