Abstract

L’invention concerne un turboréacteur comprenant : – une chambre de combustion et une tuyère ; – un circuit principal (11) incluant une pompe centrifuge principale (14) et une pompe volumétrique principale (16) alimentant en carburant des injecteurs (18) de la chambre de combustion, via un régulateur principal (17) ; – un circuit auxiliaire (13) incluant une pompe volumétrique auxiliaire (24) pour alimenter en carburant pressurisé des vérins (25) de la tuyère, via un régulateur auxiliaire (26) ; – un circuit de postcombustion (12) incluant une pompe centrifuge de postcombustion (21), un régulateur de postcombustion (22) et des injecteurs de postcombustion (23) alimentés par la pompe de postcombustion (21) via le régulateur de postcombustion (22) ; Selon l’invention, on prévoit un système secours (27) relié au régulateur auxiliaire (26) et aux injecteurs (18) pour alimenter ces injecteurs (18) en carburant avec la pompe auxiliaire (24) pour redémarrer le turboréacteur en cas de défaillance du circuit principal (11).
