Abstract
A helicopter engine collector includes an external longitudinal wall and two closed end walls, a longitudinal symmetry axis inclined ascendingly, couplings configured to be connected to purge drains, and a connection connected to a gas ejection pipe and connected to the bottom end wall. The collector also includes, in its internal space, a chamber with its symmetry axis substantially parallel to the axis of the collector. The chamber includes a longitudinal wall and two transverse end walls. The chamber is connected to the purge coupling of the injection wheel via a radial connection emerging on its longitudinal wall, the symmetry axis of the chamber being inclined, with respect to the horizontal reference ground when the helicopter is in a ground position, by a reference angle such that this axis is situated parallel to the reference ground when the helicopter is in an acceleration phase. The collector prevents formation of fumes.
