Propulsion system!
I am writing a report designing a propulsion system, ie a turbine to power an apu, and have various requirements such as a power demand for the apu of 400kW so the turbo-jet needs to have 421.05kN of power. i have various other information regarding the effiency's of the turbine.
I believe the 1st thing i need to work out is the engine inlet area, but am having trouble finding an equation which would help me work this out. I do not have a value for mass flow rate which is the next thing i believe i will need to work out but am not sure how to work out in the inlet area A without the mass flow rate!
Can anyone suggest some equations which might help or know of any useful websites or books on the subject!
many thanks, happy new year
