 how to calculate the flow through converging/diverging nozzles and the flow rate through sections
under choked and non-choked conditions
 how shock waves are formed
 methods for applying reverse thrust and suppressing jet engine noise
 the main features of burners and afterburners
 the basic configuration and operation of compressors and turbines
 how to apply the steady flow energy balance equation
 how to perform thermodynamic cycle calculations for a variety of engine types
 how to calculate the performance and efficiencies of different types of engines.




the principal features of axial- and radial-flow turbomachines
how to use dimensional analysis to scale data between geometrically similar turbomachines
how to apply the principles of mass, momentum and energy conservation to both compressible and
incompressible flow through axial turbomachines
