Unknown civil tiltrotor

[Matej]

Is somebody able to identify this tilt-rotor?

It appears to be one of the Boeing designs, however I am at a lose as to the nomenclature for it. The picture appears to be on of the many NASA pictures back when they were actually interested in VTOL commuter aircraft.

Hi,

may be it is Agusta-Bell AB-620 22-seat tilt rotor project.
