Burning Rate Behavior of Pure Nitrocellulose Propellant Samples.

摘要

Closed bomb firings have been conducted to determine the burning rate behavior of pure nitrocellulose (NC) gun propellants. Samples produced and tested included nitration levels of 12.02, 12.65, 13.11%, in both zero and seven-perforated cylindrical geometries. A sample containing basic lead carbonate was also included, Burning rates derived from the closed bomb tests were compared to strand burner data measured on samples extruded from the same NC batches. The burning rate plots for the pure NC samples show the characteristic slope changes of propellants with additives.... Interior ballistics, Closed bomb tests, Strand burner tests, Pressure.
