Regarding the powerplant problems...has anyone heard of Pratt and Whitneys next generation engines. They use ADP technology or advanced ducted prop, basically they use a gear system to to reduce fan speed relative to drive turbine speed...this might sound like all complicated to some of u cuz even im trying to figure it out...i read it last night!.
anyway this engine gives out more thrust and less noise . It propulsive efficiency is much greater thant that of current engines. It also produces a much better specific fuel consumption rate. These engines have been in testing at NASAs wind tunnels for over 15 years now.
I was wondering if anyone had any views about this kind of engine
