Abstract

Abstract Translated from French Dans un circuit de distribution de carburant de turboréacteur, on prévoît la dérivation d'un débit qc de carburant chaud prélevé en un point P2 dans la boucle de retour de la soupape régulatrice (10), débit qc que l'on peut mélanger au moyen d'un dispositif mélangeur (12) à un débit qf de carburant froid prélevé en un point Po situé en aval de la pompe centrifuge (2), afin de permettre le retour d'un débit gr du mélange tiède ainsi formé directement au réservoir de l'avion. Cette solution évite une surchauffe de la pompe HP (4) ainsi que du carburant utilisé comme réfrigérant d'un échangeur de chaleur (11′). In a turbojet fuel distribution circuit, provision is made for the derivation of a flow qc of hot fuel taken from a point P2 in the return loop of the regulating valve (10), flow qc which can be mixed by means a mixing device (12) at a flow qf of cold fuel taken at a point Po located downstream of the centrifugal pump (2), in order to allow the return of a flow gr of the lukewarm mixture thus formed directly to the reservoir of the plane. This solution avoids overheating of the HP pump (4) as well as of the fuel used as refrigerant for a heat exchanger (11 ′).
