Abstract
The number of blades in modern aircraft engines is counted in hundreds of pieces, and simultaneously the blades are responsible for correct running of the engine. Failure of even one blade could cause engine stoppage and/or its serious damage. In each engine many kinds of blades with miscellaneous shapes are working. They fulfil different roles and they run a risk of different working factors. Therefore, these are manufactured with different methods with use of various materials. Basic factors which guarantee the required operating properties of blades are shape and high precision of dimensions and also proper material used for production. To check possibilities to fulfil these requirements numerical modelling of forging processes is used.Turbine compressor blade in aircraft engine works in severe conditions, i.e. under large temperature gradient and high mechanical loads. This paper focuses on the mechanical properties of turbine blades, the blade under forged loads.
