This paper describes a mathematical model by which the off-design performance of turbofans can be predicted, knowing just the design point parameters. Off-design performance has been estimated by using gas-dynamic properties of the exhaust nozzles, which regulate the aerothermodynamic behaviour of the upstream components. Approximate overall performance of a turbofan at typical cruising conditions can be estimated, making the use of compressor and turbine maps redundant.
