A helicopter rotor include a blade, a rotor hub which supports the blade, and a lead-lag angle mechanism configured to change the lead-lag angle of the blade in synchronization with the rotation of the rotor hub. The lead-lag angle mechanism changes the lead-lag angle of the blade such that a circumferential speed of a blade tip of the blade (3) is slower on a forward side and faster on a backward side. The result is a helicopter, a helicopter rotor, and a control method of a helicopter that enable higher speed flight.
