Abstract
An exhaust nozzle 234 comprising inner and outer walls defined by a turbine casing 233 and a nacelle 230 respectively. A duct in the form of a bypass duct 232 is defined therebetween through which a bypass flow B flows in use. The nacelle 230 comprises a fixed upstream wall section 240 and at least one radially movable downstream wall section 242. At least one closure element in the form of a first slat 248 is provided, which is locatable across the second outlet 246 extending in a generally axial direction. A downstream end 250 of the first slat 248 is radially moveable between an open position in which the second outlet 246 is open, and a closed position in which the second outlet 246 is closed.
Claims14
A gas turbine engine exhaust nozzle comprising:
- radially inner and outer walls defining a duct therebetween, the outer wall comprising an upstream wall section and a downstream wall section, the duct terminating in a first outlet, a second outlet being defined between the upstream and downstream outer wall sections;
- and
- a closure element locatable across the second outlet, the closure element being mounted to the upstream wall section, wherein a downstream end of the closure element is radially moveable between an open position in which the second outlet is open, and a closed position in which the second outlet is closed.
