North American Rockwell VTOL jetliner, 1973

A preliminary design for an “Integral Lift Fan/Cruise Engine V/STOL Transport,” roughly of the same size as the Boeing 737. This design featured six dedicated high-bypass ratio turbofan liftjets (four in wing-pods, two in flip-out nacelles in the forward fuselage), and two vectorable-thrust lift/cruise engines at the tail. The design could carry 100 passengers, with two pilots and three flight attendants. The design was intended for the 1980-1985 timeframe. Range with STOL performance was 800 nautical miles; with VTOL flight, range dropped to 400 nautical miles. This was due to the need to offload fuel to reduce takeoff weight… 19,060 pounds of fuel for STOL, 12,160 pounds for VTOL. Cruise speed was to be Mach 0.75.
