DESIGN CONSIDERATION OF A SHORT-MEDIUM RANGE TURBOPROP TRANSPORT

The detail design and economic requirements of a short-medium range transport are outlined as established by discussions with the air transport industry. The design requirements in relation to the economics of the airplane are discussed, and several airplane configurations are analyzed. Analysis of these configurations indicates that a turboprop-turbojet 60 passenger airplane could be designed which would satisfy the performance and direct operating cost per seat mile requirements. A cruise speed of 400 MPH is obtainable with direct operating costs per available seat mile competitive with depreciated contemporary aircraft. Dimensional, weight and performance data of this design are shown.
