Aircraft with energy battery for cruise and power battery for take-off and landing
View Patent ↗An aircraft has an energy battery, a power battery, lifting rotors and cruise propellers and is configured such that the energy battery supplies the cruise propellers in cruising phases and the power battery supplies the lifting rotors in take-off and landing phases. The aircraft also includes a reserve power battery. The reserve power battery is configured to selectively supply power to the lifting rotors in an emergency. The reserve power battery is rechargeable, and, during the cruising phases, the energy battery is configured to charge the power battery and the reserve power battery.
1. An aircraft comprising:
an energy battery,
a power battery,
lifting rotors,
cruise propellers,
a reserve power battery that is configured to selectively supply power to the lifting rotors in an emergency and not during regular take-off and landing phases of the aircraft, and
a DC voltage converter, wherein the reserve power battery and the power battery are connected to one side of the DC voltage converter, and the energy battery is connected to another side of the DC voltage converter,
wherein the energy battery is configured to supply power to the cruise propellers in cruising phases of the aircraft, and the power battery is configured to supply power to the lifting rotors in the regular take-off and landing phases of the aircraft, and
wherein the reserve power battery is rechargeable, and, during the cruising phases, the energy battery is configured to charge the power battery and the reserve power battery.
2. The aircraft as claimed in claim 1 , wherein the aircraft has a fully electric drive.
3. The aircraft as claimed in claim 1 , wherein the aircraft comprises bent or bendable wings.
4. The aircraft as claimed in claim 1 , wherein the batteries are chargeable in a predetermined time.
5. The aircraft as claimed in claim 1 , wherein the lifting rotors are horizontally fixed ducted fans.
6. The aircraft as claimed in claim 5 , wherein the aircraft has louvers and the horizontal ducted fans are selectively able to be covered by way of the louvers.
7. The aircraft as claimed in claim 1 , wherein the cruise propellers are vertically fixed ducted fans for generating a propulsion.
8. The aircraft as claimed in claim 1 , wherein the aircraft is able to be selectively controlled in a fully autonomous manner.
9. The aircraft as claimed in claim 1 , wherein the reserve power battery is not configured to supply power to the lifting rotors during the cruising phases.
10. The aircraft as claimed in claim 1 , wherein the reserve power battery is not configured to supply power to the cruise propellers during either the cruising phases or the emergency.
