Ammonium dinitramide based liquid monopropellants exhibiting stabilised combustion characteristics and improved storage life, containing ammonia, a base weaker than ammonia, or a base which is sterically hindered, added in an amount of 0.1 to 5% of the total weight of the other components of the propellant.

Ammonium dinitrimide based liquid monopropelants exhibiting improved combustion stability and storage life

The present invention relates to a reactor for the decomposition of ammonium dinitramide-based liquid monopropellants into hot, combustible gases for combustion in a combustion chamber, and more particularly a rocket engine or thruster comprising such reactor and a combustion chamber. The invention also relates to a process for the decompostion of ammonium dinitramide-based liquid monopropellants.

Reactor for decomposition of ammonium dinitramide-based liquid monopropellants and process for the decomposition

Liquid propellants for the purpose of generating hot gases are described, which propellants comprise solution of a dinitramide compound and a fuel, and are especially suited for space applications, and exhibit the following properties exhibit the following properties: low toxicity; no toxic or combustible vapors; high theoretical specific impulse (as compared to hydrazine); high density (as compared to hydrazine); easily ignitable; storable at a temperature between &plus;10&deg; C. and &plus;50&deg; C.; low sensitivity.
