Abstract

A high energy propellant, comprising at least one oxidizer; a nitrocellul binder; an ethyl centralite stabilizer; a plasticizer; and an oxetane thermoplastic elastomer energetic binder. The oxetane thermoplastic elastomer energetic binder comprises from about zero percent to about fifteen percent by weight of the propellant. The preferred oxidizer is selected from the group consisting of CL-20, TNAZ, RDX, HMX and mixtures thereof. The oxidizer comprises from about five percent to about forth percent by weight of the propellant. The nitrocellulose binder comprises from about fifteen percent to about fifty percent by weight of the propellant and the ethyl centralite stabilizer comprises from about 0.7 percent to about 1.5 percent by weight of the propellant. The plasticizer is selected from the group consisting of TNAZ, BTTN, TMETN, TEGDN, BDNPA/F, methyl NENA, ethyl NENA and mixtures thereof. The plasticizer comprises from about five percent to about thirty-five percent by weight of the propellant.
