The Integrated Design of Aero-engines and Aero-craft

Traditionally, the airplane and aero-engineAero-engine are two separate units and are not closely related. In electric aircraftAircraft, since multiple small engines can be equipped on one airplane, the integral design of aero-enginesAero-engine with the aero-vehicle becomes feasible together with its obvious advantages. The integrated design of an airplane with multiple engines requires three key elements: 1) multiple and flexible small and lightweight aero-engine with a compact structure that is easy to operate in multiple orientations; 2) powerful and long lasting aviation electric power such as using 3D HK SC for vertical takeoff and kerosene LTG for long navigation ranges; and 3) rotatable wings allowing free-scale engine orientation, including strategies and methodologies.
