If it is too lean, the heat release will be lower and, hence, the power available will be lower. ... The engine rpm is usually limited by such factors as engine designed life (reliability of the engine) or propeller tip speed. ... The gas cycle for turbine engines can be best illustrated on a temperature/entropy diagram (see Fig. 2.1 1) . ...
