BICONICAL EXHAUST CONE FOR A CIVIL AVIATION JET ENGINE

摘要

A biconical exhaust cone for a civil aviation jet engine, this cone delimiting, on its outside, an annular exhaust stream of combustion gases and comprising an upstream frustoconical portion extending outward from upstream to downstream and a downstream frustoconical portion extending inward from upstream to downstream, wherein the downstream frustoconical portion comprises a segment which defines an outer annular surface of which one tangent, at any point along the longitudinal axis of the cone, is inclined by an angle greater than 40° and less than 90° with respect to this longitudinal axis.
