This paper presents an integrated methodology for the analysis of operationally-used turbine blades, incorporating aerodynamic and multiple structural simulations. In jet engines, blade rubbing and erosion lead to deviations ...

The formation of cracks in single crystal (SX) turbine blades is a common problem for aero-engines. To repair cracks, which are located under the tip-area, a new method is to clad with single-crystal-technology. This ...

Small deviations between turbine blades exist due to manufacturing tolerances or material inhomogeneities. This effect is called mistuning and usually causes increased vibration amplitudes and also a lower service life ...

A new contact model is proposed to simulate the forced response of a two degree of freedom mechanical model which resembles the simplest form of a friction damped turbine blade. The model scales a measured friction hysteresis ...

The disassembly of components with solidified assembly connections is often difficult to plan. A typical example can be found in the aviation industry, where turbine blades solidify in the turbine disc due to operational ...
