LAUNCHER STAGE COMPRISING A TEMPORARY SUPPORT STRUCTURE FOR TEMPORARILY SUPPORTING NOZZLE SECTIONS ALLOWING ACCESS TO THE CORE OF THE ENGINE

摘要

The invention relates to a space launcher stage (1) comprising an engine core (2), a reservoir (6) fixed on top of the engine core and a first deployable nozzle section (8a) fixed underneath the engine core, the nozzle (4) also comprising a second (8b) and third (8c) section which are intended to be situated in the continuation of one another when the nozzle is in a deployed propulsion configuration. According to the invention, the stage also comprises a nozzle section temporary support structure (14) mounted on the reservoir (6), so that the nozzle can be brought into a configuration for accessing the engine core in which configuration the sections are inserted in one another, with the third section (8c) resting against a lower support (18) of the temporary structure (14).
