A leading aircraft engine manufacturer has chosen Optomec's LENS
process for a newly-developed repair capability for damaged titanium
compressor rotor blisks. The LENS system was selected over competing
processes because it proved uniquely capable of producing material
with the desired shape, structure and properties for this demanding
application. In addition, the LENS process was able to demonstrate
economic viability to repair blisks that would otherwise cost hundreds
of thousands of dollars to replace. As part of the selection process,
the manufacturer has completed a comprehensive mechanical property
testing program which showed that the properties of the LENS material
are equal to or better than the base material.
Dave Ramahi, President of Optomec, said, "Optomec appears to be
well ahead of its competition in providing a commercial system for
blisk repair. The U.S. Air Force and a number of aircraft engine OEMs
have shown a strong interest in this capability as the industry's need
hasn't been successfully addressed by other repair techniques."
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.
Richard Grylls, LENS Product Manager, added, "The selection of the
LENS technology is further validation of the exceptional quality of
LENS-produced material, and its utility in critical aerospace repair
applications. Components repaired with the LENS process offer material
properties that meet or exceed industry's most demanding
requirements."
Optomec is the world leading provider of additive manufacturing
systems for high-performance applications in the Aerospace & Defense,
Electronics, and Biomedical markets. These systems utilize Optomec's
proprietary M3D(R) aerosol-jetting technology and LENS powder-metal
fabrication and repair technology. The company has a global customer
base of industry-leading manufacturers.
