FIELD: aviation. SUBSTANCE: device provides for both transverse and longitudinal balancing of helicopter rotor blades. Device has framework 4 on which four balances 8 are positioned. Balances are arranged near four corners of blade. They constitute four interconnected pairs intended for measuring of actual longitudinal and transverse balance of blade. Balances 8 are connected to microprocessor functionally. Microprocessor contains data on preset balancing parameters of blade to be balanced. Balancing parameters are changed by addition of weight at corresponding points of blade surface or by removal of weight. EFFECT: reduced time of balancing. 14 cl, 4 dwg
