Abstract
A fairing () for a structural element of a rotorcraft, the fairing including a rear portion () that is substantially orthogonal to the longitudinal direction (L) of the aircraft, extending between two spaced-apart trailing edges () and thus presenting a determined width, said rear portion () closing at least part of the internal volume defined by the fairing () and generating aerodynamic drag in forward flight. According to the invention, the rear portion presents, at least at the trailing edges (), a shape that is perturbed on the streamlines () of the air-flow.
