... some from Boeing !
Results of conceptual design studies of tilt rotor and tandem helicopter aircraft for a 200 nautical mile commercial short haul transport mission are presented. The trade study data used in selecting the design point aircraft and technology details necessary to support the design conclusions are included.
Rotors are driven by gas turbines in wing tip nacelles. When in forward flight, the rotors fold into the nacelles and propulsion is provided by the engines which will act as turbofans. Designs circa 1969.
