Abstract

A propulsion and lift system for an aircraft includes a wing having an outboard end and a pylon assembly coupled to the outboard end of the wing. The propulsion and lift system also includes a wing extension rotatably coupled to the outboard end of the pylon assembly. The wing extension is rotatable between a flight position in a flight mode and a stow position in a storage mode. The wing extension folds inboard in the stow position, thereby reducing a wingspan of the aircraft in the storage mode.
