Abstract (en)
[origin: WO2020212785A1] The invention relates to a manufacturing process, and to the relevant manufacturing plant, of composite solid propellant (1) for a chemical rocket motor (50) wherein at least one oxidising solid component (2), at least one polymeric liquid component (3) and at least one photo-initiator (4) are used, this photo-initiator (4) being necessary for the polymerization and the layered local crosslinking of the composite solid propellant (1). The invention also relates to the composite solid repellent (1) for a chemical rocket motor (50), obtained by the aforesaid manufacturing process or produced in the aforesaid manufacturing plant, having reduced toxicity and a lower chemical risk. The invention finds advantageous applications in the fields of civil and military aerospace propulsion, security and gas generation systems for emergency and non- emergency devices, as well as in the civil and military explosive field.
