In an effort to increase thrust, it is decided that an AFT-FAN should be added to this engine. The AFT-FAN creates a seperate cold exhaust stream. The engine has a by pass ratio of 2.0, and the fan has a pressure ratio of 1.75. The isentropic efficiencies of the fan and turbine are 0.88 and 0.90, respectively. Calculate the take off thrust assuming that the expansion in the cold nozzle is also isentropic, and that the hot nozzle area is ajusted so that hot mass flow is still 23[kg/s].
