Life of gas turbine engine components under corrosive exposure

Abstract

Currently, operation of gas turbine engines takes place in the aggressive medium of the atmosphere of some climatic regions. As a consequence, this may cause fast degradation of the strength properties of parts of gas turbine equipment and their subsequent premature failure. The problem of determining the life of gas turbine engine components under corrosive exposure is vital. We present an analysis of the state of the art in the field of assessment of gas turbine engine component life under the influence of corrosive environment in Russia and abroad. UEC-Aviadvigatel, FSUE “VIAM” and NPO “TSKTI” JSC formulated approaches to the development of the lifing process for engine parts operating in corrosive environment.
