Abstract
A flying object includes a rotation control unit and a lock control unit. The lock control unit locks a propeller in a state where the distal direction of one blade among a plurality of blades is set to a predetermined direction that is defined as a direction from the rear to the front of the flying object. An electrical angle when the distal direction of a first blade among the plurality of blades is set to the predetermined direction differs from an electrical angle when the distal direction of a second blade among the plurality of blades is set to the predetermined direction.

A flying object comprising:
- a propeller configured to be rotated by an alternating-current motor;
- and
- a control device including one or more processors that execute computer-executable instructions stored in a memory,
- wherein the propeller includes a plurality of blades having mutually different distal directions, each of the distal directions being defined as a direction from a proximal end of the blade toward a longitudinal distal end of the blade,
- wherein the one or more processors execute the computer-executable instructions to cause the control device to:
- perform rotation control, the rotation control being control that controls electric power supplied to the alternating-current motor to thereby rotate the propeller;
- and
- perform lock control, the lock control being control that maintains a mechanical angle or an electrical angle of the alternating-current motor to thereby lock the propeller,
- wherein the one or more processors cause the control device to lock the propeller in a state where the distal direction of one blade of the plurality of blades is set to a predetermined direction, the predetermined direction being defined as a direction from a rear side of the flying object to a front side of the flying object, and
- wherein the electrical angle when the distal direction of a first blade of the plurality of blades is set to the predetermined direction differs from the electrical angle when the distal direction of a second blade of the plurality of blades is set to the predetermined direction.
A flying object comprising:
- a propeller configured to be rotated by an alternating-current motor;
- and
- a control device including one or more processors that execute computer-executable instructions stored in a memory,
- wherein
- the propeller includes a plurality of blades, and
- the propeller has two or more mechanical angles at which air resistance acting on the propeller due to relative wind from a front side of an airframe of the flying object during cruising is minimized, and electrical angles respectively at which the propeller is locked at the two or more mechanical angles are all different from each other,
- wherein the one or more processors execute the computer-executable instructions to cause the control device to:
- perform rotation control, the rotation control being control that controls electric power supplied to the alternating-current motor to thereby rotate the propeller;
- and
- perform lock control, the lock control being control that maintains a mechanical angle or an electrical angle of the alternating-current motor to thereby lock the propeller, and
- wherein, when the lock control is performed after completion of the lock control at a first mechanical angle among the two or more mechanical angles, the one or more processors cause the control device to perform the lock control at a second mechanical angle different from the first mechanical angle.
