AIRCRAFT PROPELLING ASSEMBLY INCLUDING A DUCT FORMING A THERMAL BARRIER INTEGRATED IN THE CAISSON OF THE RIGID STRUCTURE OF THE ENGINE MOUNTING SYSTEM

摘要

The thermal protection system (58) of the rigid structure (10) of an attachment pylon (4) in an aircraft propulsion assembly (1) of the known type induces a penalizing increase in mass and takes up a specific volume which has to be taken into account when designing the propulsion assembly. In order to remedy these problems, the invention proposes housing the conduit (60) of the thermal protection system within the box (24) of the rigid structure, so as to take advantage of the volume assigned to the rigid structure (10). The elements (26, 62, 30) forming the conduits (60) thus form an integral part of the rigid structure and can thus play a structural role.
