Linear burning rate of double base propellant containing Azidodeoxycellulose

Azidodeoxycellulose (AC) is evaluated in a closed vessel as part of a propellant formulation containing nitrocellulose (NC) and nitroglycerin (NG) as binders. It is found that the AC systematically generates greater pressure and a faster linear burning rate when compared to a formulation having a similar concentration of a mixture of cellulose and NC that is meant to replicate a comparable substitution degree. An additional finding is that a formulation containing 13%wt of AC generates higher pressure in a closed vessel than the mixture of NC and NG alone. These results are evidence that AC is an adequate solid filler for propellant formulations.
