Flashjet Qualification Testing for Lifecycle Depainting of Rotary Wing FuseLage Skins

摘要

This program evaluated the effects of FLASHJET(registered) life cycle paint stripping on the high cycle fatigue behavior of two aluminum alloys used for fatigue critical helicopter structure. Based on the completion of five repeat paint and strip cycles, the fatigue life of 0.025 in. thick 2024-T3 or 7075-T6 aluminum is not degraded by stripping to the substrate with the FLASHJET(registered) paint stripping process, when operated within the process parameters operating range tested.
