Research on Helicopter Rotor Cone and Dynamic Balance Adjustment Method
The main source of the helicopter vibration is derived from the rotor system,drive chain system and engine power system.The rotor is in high-speed rotation during helicopter ground driving and flight,therefore,the rotor system is one of the most important factors affecting the vibration of helicopter production.This paper mainly research on the effects of rotor track and dynamic balance check on the helicopter vibration and the dynamic balance adjustment method after the helicopter rotor system is installed,which can reduce the rotor vibration level and reduce the helicopter vibration,further more,improve the helicopter performance and its quality.By analysis the long-term field helicopter dynamic balance adjustment practice and relevant vibration data,the effectiveness and reliability of the rotor track and dynamic balance method are to be proved.
