Abstract (en)

[origin: FR2849404A1] Production of a thermal protection coating on a propulsion structure involves: (a) continuously dosing and mixing (14) polyurethane(s) (I) with a mixture of polymerizable agents (II) containing predispersed fillers; (b) coating the surface of a rotating cylindrical support (2) by continuously casting a contacting spiral ribbon (18) of the mixture; and (c) prepolymerizing the mixture under ambient pressure so that (I) becomes sufficiently polymerized to be mechanically worked. Independent claims are included for: (1) the production of a propulsion structure consisting of a resistant casing with an internal and/or external thermal protection coating, where the coating is produced by the above method; and (2) a solid fuelled propulsion structure obtained by this method.
