Despite the new designed engines became more efficient and durable, blade failures often lead to loss of all downstream
stages and can have a dramatic effect on the availability of the turbine engines. In fact, the majority of gas turbo-generators
are used as an auxiliary compensator to generate electric power at the peak of load demand. Therefore they are often utilized
in discontinuous conditions of commissioning which leads to a lot of shocks, risks and premature blades’ failures.
