초록

Improved igniter compositions for rocket motors are provided which, when cured, are non-volatile and are capable of igniting under vacuum conditions and burning steadily at reduced pressures. Said igniter compositions comprise: (a) about 11% to about 13% hydroxyl terminated polybutadiene binder prepolymer; (b) about 0.7% to about 2.0% polyfunctional isocyanate curing agent for said binder prepolymer; (c) about 2.0% to about 20% metallic powder fuel; (d) about 20% to about 40% large particle size ammonium perchlorate; (e) about 30% to about 50% small part...
