A pylon conversion actuator, for use in tiltrotor aircraft, that converts the tiltrotor between hover flight mode and forward flight mode. Pylon conversion actuator selectively retracts and extends between a retracted position to an extended position. Pylon conversion actuator includes an extendable arm, a motor, and an actuator platform.

Pylon conversion actuator for tiltrotor aircraft

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.

Foldable wing extensions for aircraft

A wing is provided in one example embodiment and may include an outboard rib; a proprotor gearbox, wherein the proprotor gearbox is located inboard of the outboard rib; a fitting attached to the proprotor gearbox; and a conversion actuator, wherein the conversion actuator is attached to the wing and is mechanically coupled to the fitting. The wing may further include a downstop striker in which the downstop striker may be mounted to the fitting and the downstop striker may be between the proprotor gearbox and the conversion actuator. The wing may further include a downstop mounted on a top side of the outboard rib, wherein the downstop and the downstop striker are aligned to be in contact when the proprotor gearbox is positioned in an airplane mode.
