Abstract
(EN)
The present invention relates to a hybrid rocket engine using an electric motor-driven oxidizer pump, wherein an overheated electric motor and battery are cooled by a low temperature oxidizer, and pressure generated from the vaporization of the oxidizer is used to prevent sudden drops in pressure inside an oxidizer tank and thereby keep the shear pressure of the oxidizer pump constant to achieve stable oxidizer supply characteristics. To this end, a hybrid rocket engine using an electric motor-driven oxidizer pump comprises: an oxidizer tank storing an oxidizer; an oxidizer pump connected to the oxidizer tank via a first oxidizer supply line to pressurize the oxidizer; a driving unit which includes an electric motor for driving the oxidizer pump and a battery for supplying power to the electric motor; an auxiliary oxidizer line for guiding the oxidizer from the oxidizer tank to the electric motor of the driving unit so as to cool the electric motor; a recirculation oxidizer line for recharging an oxidizer vapor, generated through heat exchange between the electric motor and the oxidizer, to the oxidizer tank, and thereby pressurizing the oxidizer tank; and a combustion chamber connected to the oxidizer pump via a second oxidizer supply line to burn the oxidizer and a fuel.

La présente invention concerne un moteur-fusée hybride utilisant une pompe à comburant entraînée par un moteur électrique, un moteur électrique surchauffé et une batterie étant refroidis par un comburant à basse température, et la pression générée par la vaporisation du comburant est utilisée pour empêcher des chutes soudaines de pression à l'intérieur d'un réservoir de comburant et maintenir ainsi la pression de cisaillement de la constante de pompe à comburant pour obtenir des caractéristiques d'alimentation en comburant stables. À cet effet, un moteur-fusée hybride utilisant une pompe à comburant entraînée par un moteur électrique comprend : un réservoir de comburant stockant un comburant ; une pompe à oxydant reliée au réservoir de comburant par l'intermédiaire d'une première ligne d'alimentation en comburant destinée à mettre le comburant sous pression ; une unité d'entraînement qui comprend un moteur électrique destiné à entraîner la pompe à comburant et une batterie destinée à fournir de l'énergie au moteur électrique ; une ligne de comburant auxiliaire destinée à guider le comburant depuis le réservoir de comburant vers le moteur électrique de l'unité d'entraînement de façon à refroidir le moteur électrique ; une ligne de comburant de recirculation destinée à recharger une vapeur de comburant, généré par échange de chaleur entre le moteur électrique et le comburant, vers le réservoir de comburant, et ainsi mettre sous pression le réservoir de comburant ; et une chambre de combustion reliée à la pompe à comburant par l'intermédiaire d'une seconde ligne d'alimentation en comburant pour brûler l'oxydant et un carburant.
