The analysis of ship gas turbine power plant features shows that their design is similar to aircraft turboshafts which are used in helicopters. As a result, aircraft methods of non-destructive checking may be used for ship engines. Applications of the acoustic emission (AE) method for examination of the technical state of maritime power plant during repair are discussed based on the example of gas turbine blades. The following problems, which are connected with the interpretation of AE information, are decided: the stages of fatigue crack growth, criterions of crack appearance and development, and evaluation of fatigue crack length.
