A storable hypergolic solid rocket fuel comprises a mixture of a binder and a solid substance containing at least one hydrazino group. Fuels are described containing 4-amino-dihydrazino- 1,2,4-triazol, triamino-guanidine, and the carbonates, thiocyanates, and cyanides thereof. The binding agent may be a polymeric hydrocarbon, possibly combined with terpene resin. Other ingredients are Be, Mg, Al, B, Zr, hydrides of Li, Na, Be, or K, NaAlH 4 , borates of Li, Na, K, or Be, alkyls of Li, Na, K, Be, Al, Mg, or Zn, dispersions of Li, Na, or K, dihydrazino-dicyanodi-imine, or ferrocene, nickelocene, or cobaltocene. Copper chromite, a softening agent, and a surfactant may also be added. The fuel has improved reignition properties and may be used in conjunction with oxidants consisting of ClF 3 , ClF 5 , liquid O 2 , H 2 O 2 , N 2 O 4 , fuming HNO 3 plus HF, or perchloric acid.
