The book represents a survey of the contemporary methods of balancing the rotors of aircraft engines and lists the factors which influence the level of vibrations of engines. It is noted that one of the basic reasons for vibrations is the imbalance of elastically deformable rotors during operation at rpm's close to critical. Simplified methods of balancing are given, producing a considerable effect when using equipment existing in plants. Much attention is given to the complex method of the research of the dynamics of aircraft engines such as the stage preceding the selection of the means of rotor balancing. The results of research on vibrations of full scale gas-turbine aircraft engines and of their compressors and turbines are illuminated. Given is a fundamental solution of the questions connected with automation of the processes of balancing and development of new means of balancing; apparatus and equipment have been described. Basic problems in the area of the further development of the theory and practical methods of balancing of rotary systems of aircraft engines have been formulated. (Author)
