In the present work, a novel approach to the problem of hydrazine replacement is proposed. Aluminium/water slurries are suggested as potential substitutes for hydrazine. This slurry includes both the fuel (Al) and the oxidizer (H2O), and has physical properties similar to those of a monopropellant. The specific impulse of the Al/H2O bipropellant is about 300 s. The proposed propellant includes only non-toxic components; this fact significantly facilitates preparation, storage, filling, and other operations. The results of preliminary experiments with single droplets of nanoAl-gelled water slurry are reported. A new research programme is presented, which is funded by INTAS and CNES and involves six teams from France, Italy, and Russia. The programme includes studies of nanoaluminium-water slurries in order to develop the best methods for their preparation, atomisation and combustion.
