To inform and aid lighting engineers, operators, aircraft manufacturers, and regulators in their evaluation and design processes, Kopp has published a new white paper that investigates the abrasion resistance of transparent materials used in exterior jet aircraft lighting applications. The materials compared include:
The White Paper details Kopp's comprehensive two-part investigation, as follows:
Part One: The Taber Abrasion test method was used to compare how these materials withstand abrasion introduced through routine handling and cleaning of lenses.
Part Two: Independent, third-party validated high-velocity particulate impact testing was performed at the US Air Force Particle Erosion Test Facility at the University of Dayton Research Institute (UDRI). The particle erosion test apparatus, or “dust-rig,” that was used was designed to simulate erosion effects on aircraft surfaces subjected in flight to dust-laden environments.
