Abstract

Fatigue testing is a mandatory stage of the blade certification process. During the test, the blade is mounted on the block, and instrumented with heavy excitation equipment, a large number of sensors and cables. It is thus important to assess the impact of this equipment on the blade modes.This paper presents a comprehensive parametric study of the experimental and operational modal analysisperformed before and during fatigue testing. First, for reference purposes, the modal analysis of the intact, clean, blade has been performed. Next, the fatigue test has been conducted, by exciting the blade for two million cycles in flapwise, and another two million in edgewise. The modal properties of the blade have been measured at regular intervals, to track the evolution of the damage.
