Beam mounted rear propulsion system for an aircraft and aircraft with such system
First Claim
1. An auxiliary propulsive system for an aircraft, integrated within a tail cone of a fuselage, said propulsive system comprising an auxiliary jet engine, having at least one operating mode in which said auxiliary jet engine is a propulsive engine, a carrying structure to which said engine is fixed, a device for supplying external air to said jet engine, wherein:
- the carrying structure comprises beams assembled to the aircraft, overhanging rearward of a rear load carrying frame of the fuselage in a substantially longitudinal direction of the fuselage and comprises one or more rear frames behind the rear load carrying frame, the beams being interdependent of the frames at a periphery of the frames along the tail cone near coverings of the fuselage;
the auxiliary jet engine is fixed to the carrying structure by at least two lateral beams of said carrying structure, overhanging rearward a most backward frame of the rear frames, at least up to a rear attachment point longitudinal position of the auxiliary jet engine, and lateral to the engine;
the at least two lateral beams extend forward of the rear load carrying frame into the fuselage structure;
a space between the rear load carrying frame and the most backward frame being available for supplying external air to the auxiliary jet engine.

Abstract
A propulsive system for an aircraft including an auxiliary jet engine is integrated into a tail cone of a fuselage. A carrying structure of the jet engine is primarily formed with beams and frames or half-frames to which the auxiliary jet engine is fixed by lateral beams. The beams are interdependent of the frames and half-frames, and the beams are overhanging behind a frame behind which is fixed the engine. Each beam includes a lower half-beam and a higher half-beam, separated on at least a part of its length ahead from attachments of the jet engine to determine a space free of structure impediment for lateral air intakes.
