Abstract
Accurate gas turbine performance models based on thermodynamic principles can bring many benefits. In such models it is a normal practice to represent the different components by means of its performance maps or component characteristics describing the relationships between the thermodynamic variables representing the component.
It is well known that the fans of high-bypass engines have strong radial profiles of all thermodynamic variables. It is common to average these profiles so that one or two characteristic maps can represent the fan.
The present paper describes how the radial profiles can be used to make an estimation of turbofan performance. The results are somewhat different to those produced using a component performance maps.
