For three sizes of commuter aircraft for the next decade (30, 60, 90 seaters), different types of propulsion are considered: modern propellers, where Mach number (M) is greater than 0.5 and less than 0.6; open rotor systems where M is greater than 0.7 and less than 0.78; ducted propellers where M = 0.78, and turbofan where M = 0.78. Requirements are defined for each aircraft category. An optimization is done to minimize the operating cost. The results are provided versus number of seats and range.
