A main engine (14) mounted auxiliary power unit (30) comprises an auxiliary
power unit (31) integrated with a primary gas turbine engine (14) into a
single power plant suited for aircraft applications. The auxiliary power unit
(30) can be mounted within an engine core compartment of the main engine or at
the main engine aft center body. The integration of the auxiliary power unit
(30) provides for installation and certification cost savings to the airframer
by eliminating the need for mounting an auxiliary power unit (30) to the tail
section of the aircraft.
L'invention concerne une unité d'alimentation auxiliaire montée dans un moteur principal, qui comporte une unité d'alimentation auxiliaire intégrée à un moteur à turbine à gaz primaire dans un groupe motopropulseur simple, conçue pour des applications aéronautiques. Cette unité d'alimentation auxiliaire peut être montée dans le compartiment central du moteur principal ou au niveau du corps central arrière du moteur central. L'intégration de cette unité d'alimentation auxiliaire permet au constructeur de cellules de réaliser des économies sur les prix d'installation et de certification, grâce à l'élimination du besoin de monter une unité d'alimentation auxiliaire dans la partie de queue de l'aéronef.
