Abstract

L'invention concerne des turbo-machines, et en particulier des turbo-moteurs à gaz. Le turbo-moteur 10 comporte un premier compresseur 17, ayant un rotor 18 monté sur un arbre tournant 20, et entraîné en rotation par la turbine 28 du moteur, pour alimenter la chambre de combustion 24 de celui-ci en air comprimé. Le système comporte un second compresseur ayant un rotor 34, pour fournir un débit d'air auxiliaire, par un refoulement indépendant 40. Le rotor 34 du second compresseur est disposé face à face en regard du premier rotor 18. Des moyens d'admission communs 16 sont prévus pour le premier rotor 18 et le second rotor 34. Application aux turbo-machines à compresseur d'alimentation, pour faciliter le réglage du débit d'air auxiliaire, par exemple au moyen d'une couronne de vannes de guidage 42, pouvant être mises en position d'obturation au démarrage du moteur 10, pour réduire le couple résistant.The invention relates to turbo-machines, and in particular gas turbo-engines. The turbo-engine 10 comprises a first compressor 17, having a rotor 18 mounted on a rotating shaft 20, and driven in rotation by the turbine 28 of the engine, to supply the combustion chamber 24 thereof with compressed air. The system comprises a second compressor having a rotor 34, to provide an auxiliary air flow, by an independent discharge 40. The rotor 34 of the second compressor is disposed face to face opposite the first rotor 18. Common intake means 16 are provided for the first rotor 18 and the second rotor 34. Application to turbo-machines with a supply compressor, to facilitate the adjustment of the auxiliary air flow, for example by means of a ring of guide valves 42, which can be placed in the closed position when starting the engine 10, to reduce the resistive torque.
