Method of distributing propellant inside a solid-propellant casing, and tool for implementing such a method

摘要

A tank (1) containing a solid propellant (2) defining a combustion cavity (13) communicating externally through an end opening (10) of the tank is produced using a tool (12) having a rigid, strip-down plug (23), which is larger transversely than the opening, and is defined by a hollow central tubular locating body (44), and by a number of lateral forming bodies or fins (43) connectable releasably to and radiating from the tubular locating body (44); the plug being assembled inside the tank, after successively inserting the forming bodies and the tubular locating body, and by releasably locking the forming bodies by means of a hydraulic or mechanical device housed partly in the tubular locating body.
