Cellulose acetate nitrate(CAN) was used as an insensitive energetic binder to improve the insensitive munitions(IM) properties of gun propellants to replace the M1 propellant used in 105 mm artillery *** contains the energetic nitro groups found in nitrocellulose(NC),but also acetyl functionalities,which lowered the polymer's sensitivity to heat and shock,and therefore improved its IM properties relative to *** formulation,development and small-scale characterization testing of several CAN-based propellants were *** formulations,using insensitive energetic solid fillers and high-nitrogen modifiers in place of nitramine were *** small scale characterization testing,such as closed bomb testing,small scale sensitivity,thermal stability,and chemical compatibility were *** mechanical response of the propellants under high-rate uni-axial compression at,hot,cold,and ambient temperatures were also *** diameter testing,hot fragment conductive ignition(HFCI) tests were done to evaluate the propellants' responses to thermal and shock *** the propellant chemical composition,theoretical predictions of erosivity were *** the small scale test results were utilized to down-select the promising CAN based formulations for large scale demonstration testing such as the ballistic performance and fragment impact testing in the105 mm M67 artillery charge *** test results completed in the small and large scale testing are discussed.
