Multi-engine assembly and installation method for electric aircraft propulsion

A drive device for electrically driving a propeller of an aircraft, the drive device including:

• a first electric drive motor;
• at least one second electric drive motor;
• and
• a supporting frame which includes a first mounting section to which the first electric drive motor is mounted, at least a second mounting section to which the second electric drive motor is mounted, and at least one strut which interconnects the first mounting section and the second mounting section such that the supporting frame provides a cage-like structure, wherein the first electric drive motor and the second electric drive motor are individually mountable to the supporting frame;
• wherein the first electric drive motor and the second electric drive motor are operatively couplable to the propeller such that the first electric drive motor and the second electric drive motor can simultaneously and/or separately drive the propeller;
• wherein the drive device further includes a drive shaft configured to operatively couple the first electric drive motor and the second electric drive motor to the propeller, the first electric drive motor and the second electric drive motor being arranged in series in a direction along the drive shaft.
