Structural Element and Real Blade Impact Testing. Volume 1

Abstract

This report gives damage results of an experimental program concerned with performing nonrotating bench impact tests on test specimens rangine from simple cantilevered beams and plates to real fan blades. This study was carried out under Task VI Structural Element Tests which is part of the overall program Foreign Object Impact Damage Criteria. In the study, simple element specimens, such as beams and plates, were impact tested with progressive introduction of airfoil geometric parameters to validate experimentally the analytical predictions of Tasks V and VIII of the overall program. Impact tests were also conducted on actual fan blades to permit deriving correlation of the impact damage between the structural element specimens and full-scale blades. Data collected from the impact tests included accurate impact conditions, dynamic displacement of specimens at discreet points, strain/time histories local to the impact site and at critical blade stress regions identified from the structural response models, pre-test and post-test material properties, and damage assessment.
