Propulsion System Impact on Military/Commercial STOL Transport Commonality 700269
A STOL medium tactical transport featuring 1000 ft takeoff distance performance has been established utilizing the powered-lift wing to achieve STOL capability. Two powered-lift wing concepts, the augmented jet flap and the externally blown flap, are presented as optimum for a minimum thrust-to-weight ratio configuration. Interconnecting the propulsion system with engine cross ducting minimizes the unsymmetrical lift resulting from an engine failure. A commercial counterpart to the military transport is discussed.
