Features in the Transient Characteristics of Mixed and Unmixed Type Turbofans,

Abstract

Mixed and unmixed type turbofans, having identical rotating components and thermodynamic cycles, are compared in terms of transient characteristics and steady-state off-design operation. Effects of step changes in fuel flow rate, nozzle area, inlet pressure, ambient temperature and air bleed are illustrated on both the fan and compressor operating maps. Results show significant differences in the dynamic behavior of the mixed and unmixed turbofan engines without the influence of an engine control. (Modified author abstract)
