SYSTEME CORRECTEUR D'EFFET POGO CAPACITIF A TUBE DE REJET DEMI-CENTRE POSITIONNABLE DANS UN COUDE

摘要

The invention relates to a system for correcting the pogo effect (5) for a system (3) for supplying a rocket engine (2) with liquid propellent, comprising: a portion of the duct (4A) for supplying liquid propellent configured to be connected upstream and downstream from a duct for supplying liquid propellent of the supply system (3); and a hydraulic accumulator (6), comprising a tank (6A) connected to the portion of the supply duct (4A) by at least one communication opening (7); characterised in that: at least one segment (4S) of the portion of the supply duct (4A) is at least partially surrounded by the inner space (6F) of the tank (6A), each cross-section of said segment relative to the central axis (S) thereof being at least partially surrounded by the corresponding cross-section of the inner space (6F) of the tank, so that the corresponding cross-section of the inner space of the tank is off-centre relative to said cross-section of said segment (4S).
