AERODYNAMIC FAIRING DIVIDED INTO SUB-PORTIONS
First Claim
1. An aerodynamic fairing of a pylon of a turbo engine comprising:
- the fairing being in the form of a casing which extends along a longitudinal axis and which comprises a first lateral panel and a second lateral panel which are substantially parallel with the longitudinal axis and which are distributed at one side and the other of a plane of symmetry of the fairing,the aerodynamic fairing comprising at least two sub-assemblies which are arranged consecutively along the longitudinal axis and which are separated from each other by a gap,each sub-assembly comprising a frame which is oriented transversely relative to the longitudinal axis and a floor portion which extends along the longitudinal axis,each frame having, in a position for use, an upper edge, a lower edge which is fixed to an inner face of the floor portion of the sub-assembly, and a first lateral edge and a second lateral edge to which the first lateral panel and the second lateral panel are fixed, respectively.

Abstract
An aerodynamic fairing including at least one sub-assembly, each sub-assembly having a frame which is orientated transversely relative to the longitudinal axis of the fairing and a floor portion which is provided with an inner face, via which the floor portion is fixed to the frame. The fairing further comprises lateral panels which are fixed to the frame and which each extend substantially along the longitudinal axis of the fairing at one side and the other of a plane of symmetry of the fairing. The floor portions of the sub-assemblies are not mechanically connected to each other via rigid connections. The division of the floor into separate portions allows a reduction in the longitudinal thermomechanical stresses applied by the expansion of the floor under the action of the primary hot flow of the turbo reactor.
