List of tiltrotor aircraft

Bell-Boeing V-22 Osprey, the only crewed tiltrotor in production to date.

A tiltrotor is a type of vertical takeoff and landing (VTOL) aircraft that convert from vertical to horizontal flight by rotating propellers or ducted fans from horizontal positions like conventional aircraft propellers to vertical like a helicopter's rotors. ^[1]
