摘要

This paper presents cost analysis of purchase price and DOC+I (direct operating cost plusrninterest) that supports NASA’s study of three advanced rotorcraft concepts that could enterrncommercial transport service within 10 to 15 years. The components of DOC+I arernmaintenance, flight crew, fuel, depreciation, insurance, and finance. The cost analysis aims atrnVTOL (vertical takeoff and landing) and CTOL (conventional takeoff and landing) aircraftrnsuitable for regional transport service. The resulting spreadsheet-implemented cost modelsrnare semi-empirical and based on Department of Transportation and Army data from actualrnoperations of such aircraft. This paper describes a rationale for selecting cost tech factorsrnwithout which VTOL is more costly than CTOL by a factor of 10 for maintenance cost and arnfactor of two for purchase price. The three VTOL designs selected for cost comparisonsrnmeet the mission requirement to fly 1,200 nautical miles at 350 knots and 30,000 ft carryingrn120 passengers. The lowest cost VTOL design is a large civil tilt rotor (LCTR) aircraft.rnWith cost tech factors applied, the LCTR is reasonably competitive with the Boeing 737-700rnwhen operated in economy regional service following the business model of the selectedrnbaseline operation, that of Southwest Airlines.
