To clarify the fundamental burning characteristics of nitrocellulose/nitroglycerin double-base solid propellant, measurement of the burning rate, identification of the composition of exhaust gases and observation of the burning appearance were carried out under various conditions. The pyrolysis behavior of solid phase was investigated by thermogravimetry of the double-base solid propellant particles. The results were as follows.
1) The combustion of the double-base solid propellant is imperfect in the range of low burning rate.
2) The combustion characteristics of the double-base solid propellant gradually change to the theoretical ones with increase in burning rate.
3) The burning rate is increased by inserting a thin aluminum sheet in the doublebase solid propellant.
