The V-22 tilt-rotor aircraft program is one in which SIFCO Forge Group
in actively involved. The concept allows the aircraft to take off and land
vertically like a helicopter, then, once airborne, tilt its motors and fly
like a conventional airplane. SIFCO provides engine components as well as
drive train components, thus keeping the V-22 in the air. |

capabilities. |
