Aircrarft Propulsion presents thorough coverage of fundamental concepts alongwith numerous detailed examples and extensive illustrations. This accessible introduction first discusses compressible flow with heat and friction as well as engine thrust and performance parameters. Readers will then learn about aircraft gas turbine engine cycles followed by aircraft engine components. And they'll discover the aerodynamics and performance of centrifugal compressors.
