Fundamentals of the Control of Gas-Turbine Power Plants for Aircraft

It will be shown that by the use of the concept of similarity a simple representation of the characteristic curves of a compressor operating in combination with a turbine may be obtained with correct allowance for the effect of temperature. Furthermore, it bec mes possible to simplify considerably the rather tedious investigations of the behavior of gas-turbine power plants under different operating conditions. Characteristic values will be derived for the most important elements of operating behavior of the power plant, which will be independent of the absolute valu: s of pressure and temperature. At the same time, the investigations provide the basis for scale-model tests on compressors and turbines
