DTIC ADA059784: The Aerothermodynamics of Aircraft Gas Turbine Engines

An extensive study of many aspects of the aerothermodynamics of aircraft gas turbine engines is presented. The study consists of twenty-six chapters written by a total of twenty-four authors. After an initial comprehensive introductory chapter, the report provides a review of thermodynamics and gas dynamics and of laminar and turbulent flows. The cycle analysis of ideal engines is then considered, followed by the description of component losses and then the cycle analysis of non-ideal engines. Engine off- design performance is then considered followed by the description of engine/ airplane matching. Succeeding chapters consider the behavior of the various components in detail. Major problem areas such as computation of turbomachinery boundary layers, aeroelasticity and unsteady aerodynamics, engine stability, engine noise, jet noise and finally the system aspects of engine installation are considered in detail. The document is intended to serve many purposes, including those of text, design manual, research reference and comprehensive overview of the aerothermodynamics of aircraft gas turbine engines.
