A 1959 Bell Aerospace design for a Tri Service (Army, Marines, USAF) VTOL troop transport using vectorable ducted fans. This obviously led to the X-22 design. The fuselage was much like that of transport helicopters like the Chinook, boxy and unaerodynamic, but the propulsion system would provide considerably higher forward velocity.

A chart of Bell VTOL designs is HERE.

    I assume the engines are in the center of the ducts? they should have put the front-clamshell doors like a CH-37 as well as the rear ramp. roll-on-roll-off loading!
