Aircraft

An aircraft 10 comprising an energy battery 13 electrically connected to cruise propellers 11 and a power battery 14 electrically connected to lifting propellers 12. A reserve battery 15 may be connected in parallel to the power battery, to assist supplying the lifting rotors during take-off and landing. The power and reserve batteries may be recharged by the energy battery during cruising. The energy battery may have the largest energy density. The power battery may be optimized for short-term power output. The aircraft may be fully electric and capable of taking off and/or landing vertically or at short runways, e.g. VTOL, STOL, STOVL, VTHL. The aircraft may have bendable wings, a quick charging battery system, vertically fixed ducted fans for generating propulsion and horizontally fixed ducted fans for take-off and landing. Horizontal shrouded fans may be selectively covered by louvers. The aircraft may be controlled by pilot(s), or fully autonomously.
