Bell X-22 a te yon Etazini V / stol X-avyon ak kat inclinaison fanatik òganize plizyè kote. Pran-off te oaza rive swa ak elis yo panche vètikal egal, oswa sou yon pist kout ak nasèl yo panche pou pi devan nan apeprè 45 °. Anplis de sa, X-22 a te bay plis insight nan aplikasyon an taktik nan vètikal pran-off transpò twoup tankou anvan Hiller X-18 a ak siksesè a X-22, Bell XV-15 a.

The Bell X-22 was a United States 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 successor, the Bell XV-15. Another program requirement was a true airspeed in level flight of at least 525 km/h (326 mph; 283 knots). (Wikipedia).
