Abstract:

This paper summarizes the historical background and certain typical derivative cases of the core engine. The concept and advantages of the advanced versatile core engine and its derivative are expounded, and the basic methods for the advanced versatile core engine derivative are demonstrated, including the versatile core engine flow selection, thermal cycle parameters selection, component configuration selection, and efficient and stable working range determination of components. In addition, the development process of an advanced versatile core engine is introduced from the aspects of market positioning, determination of advanced performance, and core engine scheme design, and the development of the aircraft turboshaft engine, turboprop engine, turbofan engine and vehicle gas turbine derived from it is explained. The possibility and the advantages of the versatile core engine in reducing risk, shortening cycle-time, and saving expenditure are demonstrated by the practice of several versatile core engine derivative development.

Key words: advanced versatile core engine, derivative, technical and economic advantage, aero-engine, serialization
