Abstract: Hybrid electric propulsion systems (HEPS) are developed to improve power system performance, however, increases the weight of power system. A novel HEPS is proposed for a triaxial gas turbine to downsize the battery and improve the power density. It has two electric machines for high- and low-pressure shafts. The electric machines supplement or extract mechanical energy. A corresponding decoupling control scheme is developed to regulate the powers of the electric machines and decouple the common operating points from the gas turbine load. A component-level model is built to optimize the decoupling control scheme and perform the energy analysis for the novel HEPS.
