Please answer parts a, b, c, d. Thank you.The performance and design characteristics for the CF6-6 turbofan engine are listed in Table I.

Assume the following additional information:

Fan efficiency . 85%

Compressor efficiency . 87%

Turbine efficiency 89%

Turbine inlet temperature

Take-off 2760 R

Cruise ... 2560 R

The configuration is a non-mixed turbofan engine with expansion in both nozzles back to ambient.

calculate the following parameters:

a)Bypass ratio at both take-off and cruise.

b) Take-off thrust and thrust-specific fuel consumption for an engine equipped with an ideal nozzle.

c) The cruise thrust and thrust-specific fuel consumption for an engine equipped with an ideal nozzle.

d) The power required to drive the compressor-fan combination
