Abstract
Variable-axial carbon fibre reinforced polymers (CFRP) can be used to substitute titanium in structural-mechanical engine components. Such structures can be impacted by hailstones during operation. A validation strategy for a composite outlet guide vane of a hybrid titanium-CFRP-intermediate case is presented based on physical ice impact experiments starting at coupon level up to component level. For this, high velocity impact tests with spherical ice impactors were performed on the leading edge of plate specimens. An evaluation of the impact related amount of mechanical damage can be considered for the further design process and for the validation of analysis models in the virtual testing procedure. The work focuses on spherical ice impactors and the acceleration with a gas gun impact rig in regard to a reliable and reproducible testing procedure.
