Mechanisms and advantages of the variable cycle engine

Abstract
Designed for aircrafts to fly mixed missions (i.e., at subsonic, transonic, and supersonic flight speeds) with low levels of fuel consumption, the variable cycle engine is ideal for many high-speed planes. The variable cycle engine has the characteristics of both a high-bypass engine (for subsonic flight speed) and a low-bypass engine (for supersonic flight speed). As modern jet engines develop, they inevitably face a bottleneck. Therefore the VCE is seen by most as the next stage of the engines. More and more companies are beginning to invest in this new technology. This paper is targeted to explore the basic mechanism of various VCEs and to see how this new engine brings people better performance over conventional jets. Through Documental Analysis and case study, this research discovered the variable cycle engine greatly improves efficiency and reduces heat of the exiting exhaust in subsonic flight and generates higher thrust during afterburner.
