Abstract
A gas turbine engine exhaust nozzle includes a row of laterally sinuous chevrons extending from an aft end of an exhaust duct. The chevrons have radially outer and inner surfaces bound by a laterally sinuous trailing edge extending between a base of the chevrons adjoining the duct and an axially opposite apex of the chevrons. Each chevron has a compound arcuate contour both axially and laterally, and the sinuous trailing edge of the chevrons further compounds the arcuate configuration of each chevron.
Claims26
A gas turbine engine exhaust nozzle comprising a row of laterally curved sinuous chevrons extending from an aft end of an exhaust duct and spaced laterally apart to define complementary axially diverging sinuous slots, and each of said chevrons has a shallow compound contour bowl therein and is continuously sinuous axially along said slots.
A gas turbine engine exhaust nozzle comprising:
- an exhaust duct including a plurality of laterally adjoining chevrons extending from an aft end thereof;
- each of said chevrons having radially outer and inner surfaces bound by a laterally curved sinuous trailing edge extending between a base of said chevron adjoining said duct and an axially opposite apex of said chevron;
- said chevron trailing edges are continuously sinuous from said bases to said apexes;
- and
- said chevrons having a compound arcuate contour both axially and laterally.
