Abstract
Experimental data on the transient combustion of double-base propellants in a semiclosed space are presented. The transient process is initiated by a sharp change in the cross sectional area of the nozzle. The pressure in the combustion chamber at various ratios between the initial and final cross sectional areas of the nozzle is measured. An attempt to explain the experimental data obtained within the framework of the phenomenological theory of non-steady-state combustion of energetic condensed systems is undertaken. A comparison of experimental and theoretical results demonstrates their satisfactory agreement.
