2. 1. Analysis and Evaluation of Innovative Aero Engine Core Concepts

   Author : Lei Xu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intercooled recuperated cycle; intercooler; intercooled cycle; multidisciplinary optimization; turbofan; innovative core; variable core cycle; thermal efficiency; aero engine;

   Abstract : Turbofan engines, which power the majority of the modern aircraft today, have achieved such a high maturity that small improvements of the engine performance requires a large investment. More innovative technologies, including those related to the engine cores, become increasinglyattractive due to the high fuel price in recent years as well as the strict regulations on emissions.
