This paper identifies critical and relevant variable/adaptive cycle turbine engine and propulsion subsystem technologies for future next generation aviation systems. A comprehensive evaluation of key technology drivers associated with the development and demonstration of advanced Adaptive Power and Thermal Management System (APTMS) technologies applicable to next generation platforms is addressed. Specifically, the paper explores energy optimization through dynamic mission based simulations of an advanced hybrid air cycle / vapor cycle APTMS architecture combining multiple traditionally federated subsystem functions including auxiliary power, environmental control, emergency power, and engine start. The Integrated Power Turbomachine (IPTM) under development by GE Aviation (GEA) is a critical component of the advanced hybrid APTMS architecture, enabling a three-fold increase in design cooling capacity compared to current air dominance platforms, with a significant reduction in engine bleed extraction.
