Title: JT9D INDIVIDUAL ENGINE PERFORMANCE MODELLING
Author: Abu Darag, Sakhr; Gronstedt, Tomas
Abstract: The aim of this work is to pick out the be st cycle design point, wh ich gives the desired power. The selection has been done by employi ng numerical optimization algorithms, that produce a single cycle and fulfils all constrains. To build up the engine model, we estimate just six performance parameters. The search method that has been used here is the SQP method (Sequential Quadra tic program). Results show very good agreement for the thrust (f n), fan rotational speed and high pressure compressor rotational speed. Also the results represent very good agreement for pressure parameters pt3, ps4 and pt7. By contrast the maximum disagreement does not exceed 3.75% for the exit temperature (tt7).
