Review on the development status and performance deign of adaptive cycle engines

Abstract

The adaptive cycle engine (ACE) is considered a crucial candidate for the propulsion systems of next-generation aircraft. Its high thrust and low fuel consumption operating modes make it suitable for various flight missions. However, the complex couplings and novel components in the ACE pose significant challenges to its performance design. This paper presents a systematic literature review on development status and performance deign of ACEs. Firstly, the development of ACE at various periods over the past few decades is presented. Then, four typical ACE configurations are introduced and analyzed based the differences of the core and the low-pressure compression system. After that, an emphasis is placed on the performance optimization method for ACE under various operating conditions, including steady-state, mode transition, acceleration/deceleration, and considering uncertainties. In addition, the numerical zooming technology for non-rotating components, rotating components, as well as intake and exhaust system are summarized in this paper. Through the above summary and analysis, the development trends in ACE performance design are explored.
