A two-dimensional high-bypass ratio turbofan performance model was developed in order to predict accurately gas turbine transient performance. In the present model, the fan of high bypass engines has strong radial profiles of all thermodynamic variables. It is common to average these profiles so that the fan can be represented by one or two one-dimensional characteristics. The present paper describes how the radial profiles can be used to make an estimation of turbofan transient performance. The results are somewhat different to those produced using two one-dimensional compressor performance maps.
