Abstract
Abstract A gun propellant having reduced sensitivity to impact and improved burning rate, comprising crystallized NNHT particles admixed with a binder and at least one plasticizer. In a preferred embodiment, the binder is a nitrocellulose binder and the plasticizer is a liquid nitramine plasticizer. A preferred liquid nitramine plasticizer is selected from the group of ethyl nitrato ethyl nitramine and methyl nitrato ethyl nitramine. The propellant of this invention may be used or alone or may also include a quantity of RDX propellant. The propellant is suitable to be formulated for an artillery application or for a tank system.
