Abstract

A hybrid-electric propulsion system (26) for an aircraft (20) is provided that includes a propulsion unit (32), a propulsion unit gear box (30), a gas turbine engine (28), and an electric motor drive system (34). The gas turbine engine (28) has compressor, combustion, and turbine sections, and is configured to provide motive force to the propulsion unit gear box (30). The electric motor drive system (34) is disposed to provide motive force to the propulsion gear box (30) or to the gas turbine engine (28). The electric motor drive system (EMDS) (34) is adapted to interchangeably use a plurality of EMDS packages, each EMDS package including an electric motor (36) and a battery (38). The electric motor drive system (34) has a set of performance parameters that vary depending upon the particular EMDS package that is used with the electric motor drive system (34). The electric motor drive system (34) includes interfaces that allow each EMDS package to be interchangeably used.
