Many studies have considered the same problems of the combined fatigue effects, researching that combined fatigue life is more important and complex, and most studies considered turbine blades with few considering compressor blades

The gigacycle fatigue of compressor blade
(VHCF problem) with "fish eye" symptoms under the blade surface has been observed at foreign users, for example, in Russia [56, 57] (Figure 4).
The blade was a segmented section of a compressor blade
used in an aircraft engine.
The ovalizing distortion resulted in turbine and compressor blade
rubbing against the interior of the engine case and necessitated power-robbing increases in blade tip clearance gaps.
Precision engineering specialist, Weston EU, based at Foulridge, near Colne in Lancashire, has recently installed a USF VacuBlast Ventus 150 AXT automated glass bead peening machine specifically for the controlled processing of aero engine compressor blade
aerofoils for fatigue life enhancement.
A rotating turbine or compressor blade
is a piece of engineering art that brings various scientific disciplines together to convert as much thermodynamic energy into mechanical work as possible.
When Hamler Test and Analysis, an engineering consulting firm in Cookeville, Tenn., performed shaker fatigue testing of a gas turbine engine's compressor blade
, engineers used finite element analysis software.
This model showed that sweeping back the leading edge of the compressor blade
reduced shock losses.
