摘要：
In this paper, according to the engine requirements of airworthiness provisions about cooling system in CCAR 33, the modification of the design method of air system in jet engine is proposed, in which the accuracy of characteristics prediction of jet engine is improved. And meanwhile the related requirements of airworthiness provisions are analyzed. Then the modified method is applied into the turbine disk design, and the results from the new method and the old method were compared. The results discussion shows that the improvement of simulation method is useful to show the accordance with the airworthiness requirement. (C) 2011 Published by Elsevier Ltd.
