The analysis of peculiarities in compressor blade operation of the turbo-shaft gas turbine engine is carried out. At the same time the compressor blade structuring into groups is carried and it is shown that structural groups of blades operate under different conditions of operation. It is defined, that different structural groups of compressor blades have their own definite peculiarities of operation and erosion wear. It is shown, that the erosion wear of all groups of compressor blades may be characterized by irregularities of three kinds. In the paper a general approach to life increase of all groups of compressor blades in a helicopter gas turbine engine is offered.
