n.— «Aircraft engines can be damaged by foreign objects entering the engine and hitting the fast-spinning airfoils. Modern jet engines use integrally-bladed rotors, often known as blisks, which are made using materials of the highest quality in order to improve efficiency while ensuring safety. To repair these components, material added to restore the damaged blisk airfoils must meet the same stringent property requirements as new components.» —“Aircraft Engine OEM Selects Optomec’s LENS ® Technology for Blisk Repair” in Albuquerque, New Mexico BusinessWire Mar. 16, 2007.
