헬리콥터 주로터 블레이드 동적 발란싱 개념 연구

Dynamic balancing of Composite blades must be done to be sure to minimize vibrations before installation on helicopter. Iinitial production blades of KUH(Surion) was carried out by shipset unit, but dynamic balancing using master blade is need to secure the interchangeability of each blade in order to decrease maintenance costs and times in the second production phase. In this paper, master blade selection process and its application for second production phase of KUH main rotor blade are described.
