Effect of the FlashJet Paint Removal System on Rotor Blade Skin Materials

摘要

The U.S. Army Aviation and Missile Research, Development, and Engineering Command in Huntsville, AL, requested the U.S. Army Research Laboratory Weapons and Materials Research Directorate at Aberdeen Proving Ground, MD, to develop and execute a program aimed at evaluating the effect of the FlashJet coating removal system on the mechanical properties of the typical U.S. Army aviation blade skin materials. The skin materials representative of the three most common U.S. Army helicopters were assessed. Fatigue, tensile, and short-beam shear tests were conducted. Test panels from six specimen groups were evaluated: baseline (as-painted), hand-sanded, stripped-to-primer, stripped-to-substrate, stripped-to-substrate plus two additional passes, and lifecycle.
