Embodiment Construction

[0046] Figure 4 An engine assembly 52 is shown comprising:

[0047] - engine 54 in which the core air flow flows,

[0048] - an engine nacelle 56 positioned around the engine 54 so as to define with it an annular duct in which a bypass flow of cold air flows, and

[0049] - A pylon 58 providing the connection between the engine 56 and the wing 60 of the aircraft.

[0050] The pylon 58 includes a rigid primary structure 62, which serves, among other things, to transmit forces between the engine 54 and the rest of the aircraft, and a secondary structure 64 which encloses the primary structure 62, And reduce the resistance of hanger 58.

[0051] A more detailed description of these elements of the engine assembly is not given, since they may be identical to those of the prior art.

[0052] For the remainder of the description, the longitudinal direction is a direction parallel to the engine axis A54. A transverse plane is a plane perpendicular to the longitudinal direction....

Abstract

The invention relates to a heat exchange device, an aircraft pylon, and an aircraft. The heat exchange device is positioned in an aircraft pylon and comprises a heat exchanger and an obturator to adopt a closed state where it prevents flow of air from flowing through the heat exchanger, and more- or less-permissive states where it allows flow of air to flow with a higher or lower flow rate. The obturator includes slats each including a pivot axis, the pivot axes of the various slats being mutually parallel and intersecting the direction of the flow of air, the slats being simultaneously mobilein rotation about their pivot axis between a closed position in which the slats are contiguous, which corresponds to the closed state of the obturator, and an open position in which the slats are spread apart, which corresponds to the permissive state of the obturator.

Description

technical field [0001] The present application relates to a compact heat exchange device incorporated into an aircraft pylon. Background technique [0002] according to figure 1 and figure 2 In the configuration shown in FIG. 1 , aircraft 10 includes a plurality of engine assemblies 12 positioned under wings 14 . [0003] Such as figure 2 As shown, engine assembly 12 includes: [0004] - engine 16, in which the core air flow flows, [0005] - an engine nacelle 18 positioned around the engine 16 so as to define with it an annular duct in which a bypass flow of cold air flows, and [0006] - A pylon 20 providing the connection between the engine 16 and the wing 14 . [0007] The pylon 20 includes a rigid primary structure 22 for, among other things, transmitting forces between the engine 16 and the rest of the aircraft 10 , and a secondary structure 24 that encloses the primary structure 22 , and reduce the resistance of the hanger 20. [0008] Such as figure 2 and...
