摘      要：The gas turbine engine internal air system provides cooling and sealing air to a series of critical subsystems and components such as high pressure gas turbine blades,as well as controlling the thrust load on the turbine and compressor spool *** potential variations for the internal air system are possible,depending on the requirement,expertise and command of intellectual *** subsystems,such as rim seals,pre-swirl systems,and rotating cavities have been the subject of extensive development and analysis leading to robust design *** there remains scope for further consideration of the overall system design,and this paper explores the use of a decision analysis tool called morphological analysis applied to the internal air *** analysis provides an effective means for tackling issues where there is uncertainty,as is the case with many design scenarios,including the internal air system,with some specific parameters and information not available until later in the design phase,after the key geometry has been *** problem space comprising seven principal parameters,and a cross consistency matrix which allows identification of compatible and incompatible states are presented.
