Abstract:N-Nitrodihydroxyethyl dinitrate(DINA)is a useful energetic plasticizer in double base(DB) propellant,which is beneficial to energy increase and ablation reduction.,due to its advantages over nitroglycerin (NG)such as the high capability to solve and plasticize the high nitrogen content nitrocellulose(NC) and larger specific volume. In this paper the effects of these factors on the formulation and properties of DB propellant are analyzed and discussed ,and some data would be useful for the research and manufacture thereof.
