ABSTRACT:
A method of making a thermally-protective coating on a thruster structure, the method consisting in: continuously measuring out and mixing (14) at least one polyurethane and a mixture of polymerization agents in which specific fillers have previously been dispersed; coating a rotating cylindrical support surface (2) by continuously casting a strip (18) of touching turns of the resulting mixture; and pre-polymerizing the resulting coating at ambient pressure so that said polyurethane becomes polymerized sufficiently to be capable of being stressed mechanically.
