Self-propelled engine with separable stages

摘要

A self-propelled engine, such as a rocket, is described which is intended to be launched from a tube, comprising a front stage and a rear accelerating stage, means for achieving the separation of the two stages at the end of the combustion of the propellant charge contained in the acceleration stage, said propellant charge being integral with the front wall of the rear acceleration stage, wherein the front wall includes a first fixed part and a second part capable of sliding along the axis of the engine, said front wall parts each carrying respective propellant charges separated by a partition fixed in leakproof manner to one of said parts of the front wall. The second part which slides rests against the front stage, and the charge carried by the second part has a slightly longer combustion time than that carried by the first part which is fixed.
