Control device for aircraft

A control device for an aircraft,

• the aircraft comprising:
• a plurality of vertical take-off and landing (VTOL) rotors each including one or more blades and configured to generate vertical thrust by rotating about a rotation shaft;
• at least one cruise rotor configured to generate forward thrust;
• and
• at least one fixed wing configured to generate lift when a fuselage has an airspeed,
• the control device comprising one or more processors configured to execute computer-executable instructions stored in memory, the control device configured to operate the aircraft in a horizontal cruising mode and in a VTOL mode,
• wherein, during operation in the horizontal cruising mode, the one or more processors execute the computer-executable instructions to simultaneously cause the control device to:
• control the rotational speed of the cruise rotor to generate forward thrust;
• perform pitch control that controls a pitch of each of the blades of the VTOL rotors;
• control each of the VTOL rotors to stop at a predetermined angle;
• maintain a stopped state rotation angle of each of the VTOL rotors;
• and
• generate moments around a center of gravity of the fuselage by lift and drag generated at each of the blades through the performance of the pitch control that controls the pitch of each of the blades of the VTOL rotors;
• and
• wherein, during operation in the VTOL mode, the control device is configured to:
• control a rotational speed of each of the VTOL rotors, and
• change the pitch of the blades of each VTOL rotor.
