Abstract: A model for simulating the performance of mixed flow turbofan engines was presented based on the component characteristics of the engines. Numerical method was obtained using three layer iterations, and the computer program to fulfil this was developed. An example for predicting the performance of an augmented turbofan engine was given. Comparisons between numerical results and experimental data showed good agreements. It was remarkable that proposed method was robust, and was computationally fast. It is apparent that this method is readily adaptable for analyzing full fight-envelope operation and combined control modes of coming generation military engines.
