Abstract
An assembly is provided for an aircraft. This aircraft assembly include an airframe with a horizontal axis. The aircraft assembly also includes a powerplant arranged with the airframe. The powerplant includes a gas turbine engine, an exhaust nozzle and a flowpath fluidly coupling the gas turbine engine to the exhaust nozzle. The exhaust nozzle includes a support structure and a plurality of nozzle flaps disposed on opposing sides of the flowpath. Each of the nozzle flaps is pivotally connected to the support structure. The exhaust nozzle is configured to exhaust combustion products received from the gas turbine engine along a first trajectory when the nozzle flaps are pivoted into a first arrangement. The first trajectory is angularly offset from the horizontal axis in a vertical upward direction.
