Abstract

A hybrid-electric propulsion (HEP) system (20) for powering an aircraft is provided. The HEP system (20) includes an inlet case (28), an engine output shaft (48), a gearbox (26), a gas turbine engine (22), an electric motor (24; 24A), and a gear system (54; 54A, 54B). The inlet case (28) forms a cavity (58) of the HEP system (20). The engine output shaft (48) is disposed within the cavity (58) and extends axially along a first rotational axis (62). The gearbox (26) is in drive communication with the engine output shaft (48), and the gas turbine engine (22) in drive communication with the engine output shaft (48). The electric motor (24; 24A) is in drive communication with the engine output shaft (48). At least a portion of the electric motor (24; 24A; 24B) is disposed within the cavity (58). The gear system (54; 54A, 54B) is configured to rotatably engage the electric motor (24; 24A) with the engine output shaft (48).
