    摘要: A helicopter rotor include a blade, a rotor hub which supports the blade, and a lead-lag angle mechanism configured to change a lead-lag angle of the blade in synchronization with a 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 slow on a forward side and fast on a backward side. Accordingly, a helicopter, a helicopter rotor, and a control method of helicopter that enable high speed flight are provided.
