Experimental analyses of laboratory-type composite solid rocket propellants and hybrid solid fuels based on -AlH3 (alane) are presented. Chemical and physical properties of this peculiar energetic ingredient are discussed, ballistic properties experimentally evaluated under a variety of configurations, and flame structures compared with the corresponding aluminized propellants. The obtained results overall disclose a competitive performance of alane-based propellants with respect to the aluminized formulations and encourage its use in both solid and hybrid rocket propulsion for space exploration.
