Abstract:
(EN) Disclosed is a method for managing the thrust of a rocket engine (100) by which an initial thrust setpoint (PGCc ini) is computed. Taking into account at least one limitation of the electrical power supply (104), a filtered thrust setpoint (PGCc f) is then computed for the engine (100) by performing at least one of two sets of operations (S31, S32, S33; S35, S36, S37, S38). These two sets of operations comprise operations intended as a safeguard for any malfunction of the rocket engine that could occur due to a lack of sufficient available electrical power. Also disclosed is a computer program and recording medium for implementing said method, a control device for implementing said method, and a rocket engine comprising such a control device.
(FR) Procédé de gestion de la poussée d'un moteur-fusée (100) suivant lequel on calcule une consigne initiale de poussée (PGCc ini). On calcule ensuite, compte tenu d'au moins une limitation de l'alimentation électrique (104), une consigne de poussée filtrée (PGCc f) pour le moteur (100), en réalisant au moins l'un de deux groupes d'opérations (S31,S32,S33; S35,S36,S37,S38). Ces deux groupes d'opérations comprennent des opérations visant à assurer tout dysfonctionnement du moteur-fusée qui pourrait survenir faute d'une puissance électrique disponible suffisante. Programme d'ordinateur et support d'enregistrement pour la mise en œuvre de ce procédé. Dispositif de commande permettant la mise en œuvre de ce procédé, et moteur-fusée comprenant un tel dispositif de commande.
