Abstract
Connecting turbomachinery rotor blades by interblade linkage is a widely used technique of boosting reliability and strength of axial flow impellers of gas engines and power generating turbines. Stress levels from forced vibrations are highly sensitive to small deviations in blade geometry and the dimensions of the blade-shroud assembly. Deviations by 1–2% may lead to a change of stress levels by a factor 1.5 to 2.0. Therefore knowledge of most favorable and most disadvantageous deviations in sets of blades, such as may occur within manufacture tolerances, is of importance.
