Problems solved by technology

Due to this larger size of the rear attachment, the fairing around the rear attachment presents an equally large congestion in the auxiliary flow path, which results in considerable drag

Embodiment Construction

[0040] First refer to figure 1 , shows an aircraft 100 of a commercial type comprising a rear part 1 provided with two engines 2 partially embedded in the fuselage 4 from the fuselage frame 6 Protruding, oriented parallel to the lateral plane of the aircraft and covered by an outer fuselage skin. Two engines 2 are positioned laterally on the fuselage, on either side of the median vertical plane P1 of the rear part 1, wherein said two engines are able to take in part of the boundary layer of the air circulating on the fuselage.

[0041] figure 2 and Figure 2a One of the two engines 2 is shown, it should be noted that only one of the two engines 2 will be described below since both engines 2 are of the same or similar design.

[0042] Here, the engine 2 is a turbofan engine centered on the longitudinal axis 8 . In this regard, it should be noted that in the remainder of the description, the terms "forward" and "aft" should be considered relative to the propulsion direction...

Abstract

The invention relates to a rear portion of an aircraft. In order to reduce the congestion of the attachment means for aircraft engines (2) in a secondary vein, a first fuselage frame (6a) has two sideportions (34a) for supporting the engine, each associated with one of the two partly buried side engines, these portions (34a) being curved inwards so as to surround and follow the profile of the outer shroud (26) of an intermediate case (14). The side portion (34a) is attached on this shroud (26) through first and second attachment arrangements (40-1, 40-2) spaced apart from each other circumferentially, these arrangements being configured in order to allow absorption of the forces related to the torque along a longitudinal direction (X) of the engine.

Description

technical field [0001] The present invention relates to the field of aircraft comprising a rear part equipped with two engines partially embedded in the fuselage to be able to suck in part of the boundary layer. These engines are also referred to as propulsion by boundary layer intake or boundary layer intake (BLI) type engines. It is known that propulsion by boundary layer intake corresponds to engine intake of the low kinetic energy air flow circulating around the rear part of the fuselage. This technology can reduce the kinetic energy consumed by propulsion and aircraft drag, thereby reducing fuel consumption. Background technique [0002] Boundary layer suction engines are known to be mounted on the rear part of the fuselage. These boundary layer suction engines are, for example, two partially embedded or semi-buried engines projecting laterally from the rear part of the fuselage. [0003] These engines are conventionally mounted on the fuselage by means of suspension...
