The Bell X-22 is an American V/STOL X-plane with four tilting ducted fans.
Take-off was to selectively occur either with the propellers tilted vertically upwards or on a short runway with the nacelles tilted forward at approximately 45°.
Additionally, the X-22 was to provide more insight into the tactical application of vertical take-off troop transporters such as the preceding Hiller X-18 and the X-22’s successor, the Bell XV-15.
