PROPULSEUR COMBINE PERMETTANT DE COMBINER LES AVANTAGES SPECIFIQUES D'UN MOTEUR A TURBOSOUFFLANTE ET D'UN MOTEUR A TURBOPROPULSEUR.IL COMPREND UNE TURBINE A GAZ 10, UNE SOUFFLANTE 12 ENTOUREE D'UN CAPOT 50, AU MOINS UNE HELICE 14 ET DES MOYENS DE TRANSMISSION 16, 28 DISTRIBUANT UNE PARTIE DE L'ENERGIE PRODUITE PAR LA TURBINE A GAZ A LA SOUFFLANTE 12 ET UNE AUTRE PARTIE A L'HELICE 14. DE PREFERENCE, LE PROPULSEUR COMPORTE DES AUBES DISTRIBUTRICES D'ENTREE 60 A GEOMETRIE VARIABLE QUI PERMETTENT DE FAIRE VARIER LA REPARTITION DE L'ENERGIE MOTRICE ENTRE LA SOUFFLANTE ET L'HELICE.APPLICATION AUX MOTEURS D'AVION. A compound propulsor for powering a vehicle, such as an aircraft. A compound propulsor includes a core gas turbine engine, a fan encased within a cowl, at least one propeller, and drive means for distributing a portion of the power produced by the core engine to the fan and another portion to the propeller. Preferably, the compound propulsor also includes variable geometry inlet guide vanes for varying the portions of power distributed to the fan and propeller.
