Abstract
Some apparatus embodiments include an aircraft having a hybrid parallel electric propulsion system including two internal combustion engines and an electric propulsion system including two electric motors electrically connected to an electric power module. The electric power module is optionally configured for attachment to a bottom side of a fuselage. Each of the electric motors attaches to an aircraft wing outboard of the nearest internal combustion engine. The electric motors and internal combustion engines are operable independently of one another, providing for propulsion by the electric motors during flight and ground operations when the internal combustion engines may operate inefficiently. Some embodiments are implemented as a hybrid parallel electric propulsion retrofit package for adding an electric propulsion system to an aircraft previously equipped only with internal combustion engines.
