The invention relates to the technical field of unmanned helicopters, and particularly discloses a seesaw type unmanned helicopter rotor structure and a chordwise dynamic balance trimming method. The rotor structure is simple in overall structure and convenient to operate, chordwise dynamic balance trimming of a rotor can be achieved under the condition that independent balance weight is not carried out, the dynamic balance trimming efficiency of the unmanned aerial vehicle rotor wing is greatly improved, and the trimming operation of dynamic balance of the unmanned aerial vehicle rotor wing is simplified. According to the method disclosed by the invention, the chordwise dynamic balance of the rotor wing can be quickly and conveniently adjusted without additionally adding a counter weight or adding a structure for mounting the counter weight. The weight of the counter weight can be effectively reduced; the dynamic balance adjustment time is shortened; the complexity of the aircraft structure is reduced; the maintenance time of the unmanned aerial vehicle is reduced. And the economy and the safety of the unmanned helicopter are improved.
