Abstract: An unmanned aerial vehicle (UAV). The UAV includes a plurality of combustion engine modules, each combustion engine module including a respective helicopter blade propulsion system. A truss connects and separates adjacent pairs of the combustion engine modules of the plurality of combustion engine modules. Each truss includes a hollow interior portion configured to hold a fuel for at least one of the plurality of combustion engine modules. The UAV also includes a control system configured to allow a user to control the plurality of combustion engine modules and corresponding helicopter blade propulsion systems.
