Abstract

This study is concerned with the understanding, analysis, and prediction of major damage mechanisms in helicopter blade components subjected to a high velocity impact load. Two types of impact are studied: the frontal impact, which corresponds to a normal impact on the leading edge, and the oblique impact on the skin of the lower surface of the blade.

Several tests are performed to identify the parameters that control the response of the structure and the chronology of damage development.

Dynamic finite element models of the phenomena observed experimentally are proposed. To overcome the problems related to the size of the modeled structure, original modeling strategies are developed to accurately represent the damage observed. The calculated impact behavior and amount of damage are validated by comparison with experimental test results.
