[ What is claimed is:] [1.]1. A pyrotechnic double-composition charge comprising an encapsulated main pyrotechnic charge (23) having a linear burning rate V.sub.1 at least equal to 25 mm/s under a pressure of 20 Mpa and at least part of the surface of said main charge being covered with an external skin (24) of pyrotechnic composition adhering to the said main charge by simple deposition, said skin having a thickness of less than, or equal to, 0.1 mm and having a linear burning rate V.sub.2 which satisfies, under a pressure of 20 Mpa, the relationship 0.05 V.sub.1.ltoreq.V.sub.2.ltoreq.0.5 V.sub.1.
