WebbMonel™ Frames. Monel is a nickel alloy containing 68 percent nickel, 30 percent copper, and two percent iron. Monel,™ the most commonly used frame material today, is often used for components that require sturdiness and rigidity, such as temples and bridges. Pros: Strong and can also be welded, brazed, and soldered. Boeing, General Electric Aircraft Engines, Goodrich Corporation, NASA, Texas A&M University and All Nippon Airways developed the Variable Geometry Chevron using a NiTi SMA. Such a variable area fan nozzle (VAFN) design would allow for quieter and more efficient jet engines in the future. In 2005 and 2006, Boeing conducted successful flight testing of this technology. SMAs are being explored as vibration dampers for launch vehicles and commercial jet engines. …
