Abstract
A hybrid aircraft that flies by using a plurality of rotors (takeoff and landing rotors and cruise rotors) includes a generator, a battery charged with power generated by the generator, a plurality of electric motors that rotate the respective rotors by the power generated by the generator and power supplied from the battery, and a controller that sets a target remaining capacity of the battery according to a flight state of the aircraft and controls charging and discharging of the battery so that the remaining capacity of the battery approaches the target remaining capacity.
Claims11
A hybrid aircraft that flies using a plurality of rotors, the hybrid aircraft comprising:
- a generator;
- a battery charged with power generated by the generator;
- a plurality of electric motors configured to rotate the respective rotors by the power generated by the generator and power supplied from the battery;
- and
- a controller configured to estimate, according to a flight state of the hybrid aircraft, a power fluctuation value that is a fluctuation value of power used by the plurality of electric motors, set a target remaining capacity of the battery based on the fluctuation value of power, and control charging and discharging of the battery in a manner that a remaining capacity of the battery approaches the target remaining capacity.
A hybrid aircraft that flies using a plurality of rotors, the hybrid aircraft comprising:
- a generator;
- a battery charged with power generated by the generator;
- a plurality of electric motors configured to rotate the respective rotors by the power generated by the generator and power supplied from the battery;
- and
- a controller configured to set a target remaining capacity of the battery according to a flight state of the hybrid aircraft, and control charging and discharging of the battery in a manner that a remaining capacity of the battery approaches the target remaining capacity,
- wherein
- the controller sets the target remaining capacity to be low when the hybrid aircraft moves in a vertical direction, and sets the target remaining capacity to be high when the hybrid aircraft moves in a horizontal direction.
