    Abstract: Electrically powered Vertical Take-off and Landing (VTOL) aircraft are presented. Contemplated VTOL aircraft can include one or more electrical energy stores capable of delivering electrical power to one or more electric motors disposed within one or more propeller housings, where the motors can drive the propellers. The VTOL aircraft can also include one or more back-up and/or secondary energy/power sources (e.g., batteries, engines, generators, fuel-cells, semi-cells, etc.) capable of driving the motors should the energy stores fail or deplete. The VTOL aircraft will be significantly different to regular Tiltrotor aircraft as we use propellers and a modern steering system that reduces complicity dramatically. The contemplated configurations address safety, noise, and hover stability and outwash concerns to allow such designs to operate in built-up areas while retaining competitive performance relative to existing aircraft.
