The balance of helicopter rotors is one of the key factors affecting their flight stability and safety.The traditional mechanical balancing method has problems such as slow response speed and low accuracy,which makes it difficult to meet the requirements of modern helicopters for high performance and high reliability.In order to carry out research on real-time adjustment technology of helicopter rotors in China,the automatic balancing technology of helicopter rotors was studied based on fuzzy control theory,and wind tunnel tests of IFT model rotor automatic balancing were conducted.The test results confirmed that the rotor automatic balancing technology based on fuzzy control theory is safe and effective,achieving intelligent pitch variation while controlling rotor vibration level.
