Engineering Calculations for Gas Turbine Engines by the Methods of Small Deviations

摘要

This book is intended for engineers engaged in the research, development, and designing of stationary and aviation gas-turbine engines and it may also be useful to professors and student in schools of higher education. A simple method is presented of calculating the interdependence of the working process parameters of all contemporary types of gas-turbine engine arrangements, i.e., turbojet, engines with two-stage compressors, and so forth. The effect of variations in parameters or the chracteristics of engine components, e.g., coefficient of losses, efficiency, etc., on thrust, power, air intake, and fuel are calculated by the method of small deviations and converted into a system of linear algebraic equations, which yield both general and specific answers to practical problems. Examples illustrating the use of the method are given and the limitations of the method as well as its margin of error are also covered. (Author)
