An ultra-efficient “green” aircraft propulsor utilizing an augmentor fan is disclosed. A balanced design is provided combining a fuel efficient and low-noise high bypass ratio augmentor fan and a low-noise shrouded high bypass ratio turbofan. Three mass flow streams are utilized to reduce propulsor specific fuel consumption and increase performance relative to conventional turbofans. Methods are provided for optimization of fuel efficiency, power, and noise by varying mass flow ratios of the three mass flow streams. Methods are also provided for integrat...
1. A method of generating thrust with an aircraft propulsor having an augmentor fan, a core engine, and a ducted fan, the method comprising providing thrust from the core engine at a first thrust to total power ratio;providing thrust from the ducted fan at a second thrust to total power ratio; andproviding thrust from the augmentor fan at a third thrust to total power ratio,wherein the third thrust to total power ratio is greater than the second thrust to total power ratio for a first set of flight conditions,wherein the first set of flight conditions co...
