FIELD: machine building.
SUBSTANCE: casing of the solid fuel grain igniter from composite materials, comprises a cylindrical shell with an outer heat-insulating coating. The cylindrical shell has a flat bottom on one side and a free end with an internal thread on the other. The free end is closed with dome shaped removable cap with nozzle openings at the top and support-protective grid in the inner cavity. The threaded part of the cap is designed as a sleeve connected to the cap by an adhesive and having a layer fabric reinforcement perpendicular to the thread axis. The cap is entirely made of reinforced fabric with eyelet and a thread, which is an extension of the sleeve thread.
EFFECT: invention allows for the improvement of the solid fuel grain igniter reliability.
