Title
(EN) FAN NOZZLE WITH WALL THICKNESS DISTRIBUTION
(FR) BUSE À JET PLAT À ZONE VARIABLE AVEC RÉPARTITION D'ÉPAISSEUR DE PAROI
Abstract
(EN)
A variable area fan nozzle for a gas turbine engine includes a radially outer wall and a radially inner wall. At least one of the radially outer wall and the radially inner wall includes a wall thickness distribution that has local thick portions and local thin portions.
(FR)
L'invention concerne une buse à jet plat à zone variable pour un moteur de turbine à gaz, qui comprend une paroi radialement externe et une paroi radialement interne. La paroi radialement externe et/ou la paroi radialement interne comprend une répartition d'épaisseur de paroi qui présente des parties locales épaisses et des parties locales fines.
