House of Representatives Committee Recommends Funding and Further Military Adoption of Laser Peening

The House of Representatives Committee report on Armed Services (H. Rept. 113-102) accompanying the National Defense Authorization Act for Fiscal Year 2014 recognized that laser peening “has achieved considerable success in commercial aerospace and power-generation applications” because it is “a surface enhancement processing treatment for metals… reducing costs by enabling improvements in the metal structure and mitigating high-cycle fatigue failures of a system, thus extending the system’s lifetime.”

The committee further recommended specific funding for the application of laser peening on the F-35 Pratt & Whitney F-135 engine and reaffirmed its 2012 recognition of laser peening as having “the potential to save significant funds through the reduction of fatigue failure, [and] stress corrosion cracking… in a wide range of military equipment, including aircraft.”  They recommendation included that the military “examine the potential cost savings that may be derived from adopting [laser peening] broadly across the military services, particularly for use on engines, aircraft structures, land vehicles and weapon systems.”

LSP Technologies provides laser shock peening for an IBR component in Pratt & Whitney’s F-119 engine, which served as the design model for the F-135 engine, and could easily adapt its laser peening process from the F-119 to the F-135 engine components.  LSP Technologies has laser peen processed over 40,000 blades for the aerospace and power generation industries, and has a proven quality record in the industry.

See the complete 2014 house report here, and look for the recommendations to use laser peening on pages 62 and 119.  The sections related to laser peening in the two committee reports are reproduced below.

Aircraft engine component laser peening

The budget request contained $139.4 million in PE 27268F for the aircraft engine component improvement program.  In the committee report (H. Rept. 112–78) accompanying the National Defense Authorization Act for Fiscal Year 2012, the committee noted that laser peening technology had the potential to save significant funds through the reduction of fatigue failure, stress corrosion cracking, and component shape corrections in a wide range of military equipment, including aircraft. The committee believes that the Air Force should consider use of aircraft engine component improvement program funds to examine the potential benefits of laser peening for F–135 engine components in order to see if reliability could be improved and if engine life-cycle costs could be reduced.  The committee recommends $139.4 million, the full amount requested, in PE 27268F for the aircraft engine component improvement program.

Laser Peening Technology

In the committee report (H. Rept. 112–78) accompanying the National Defense Authorization Act for Fiscal Year 2012, the committee noted that ‘‘laser peening technology, a surface enhancement processing treatment for metals, has achieved considerable success in commercial aerospace and power-generation applications, reducing costs by enabling improvements in the metal structure and mitigating high-cycle fatigue failures of a system, thus extending the system’s lifetime.’’ In that report the committee also encouraged the Department of Defense ‘‘to examine the potential cost savings that may be derived from adopting this technology broadly across the military services, particularly for use on engines, aircraft structures, land vehicles and weapon systems.’’ However, the committee is concerned that some military departments have not fully explored the use of such technologies to reduce costs associated with problems of fatigue failure, stress corrosion cracking, and component shape corrections. The committee further encourages the Department to explore such technologies for use in aircraft engines to slow the rate of replacement of highly stressed components and parts.

See the complete 2012 committee report here, and look at page 104 for the section on laser peening.

Laser Peening Technologies

The committee is aware that laser peening technology, a surface enhancement processing treatment for metals, has achieved considerable success in commercial aerospace and power generation applications, reducing costs by enabling improvements in the metal structure and mitigating high-cycle fatigue failures of a system, thus extending the system’s lifetime. The committee encourages the Department of Defense to examine the potential cost savings that may be derived from adopting this technology broadly across the military services, particularly for use on engines, aircraft structures, land vehicles and weapon systems. The committee notes that this technology could reduce costs associated with problems of fatigue failure, stress corrosion cracking, and component shape corrections. The committee further notes that the cost savings derived from the use of laser peening technology could fund a wider deployment of the technology, with the goal of slowing the rate of replacement of highly stressed components and parts.


Publication comments on total cost of product failure

While recently reviewing a engineering simulation publication (Advantage, VOL VII, ISSUE 2), I came across several text excerpts that resonated with the focus of LSP Technologies.

From the article “Keeping Your Product Promise”:

“As recent headlines attest, the financial cost of product failure can have a major impact on a company’s bottom line – eroding current profit margins and impacting future financial as potential warranty costs are built into the forecast. There are other long-term costs of product failures that may be less tangible but equally important.  Today, thanks to the expansion of social media, a single dissatisfied customer can share his or her views with the world in seconds, via a single mouse click.  Though harder to measure than warranty costs, negative product reviews can cause irrevocable damage to any manufacturer’s hard-won brand equity.”

Costs of product failures total much more than just the part value. Customer relationships are the strongest foundation for a business, and one area in which LSP Technologies places heavy emphasis.  If you’re in need of product life enhancement, contact us to discuss how we can help you and your customers.

From the article “Robust Design at Pratt & Whitney”:

“Many components of jet engines require cast materials with long lead times.  This results in the need to design parts and commit to geometry long before thermal boundary conditions are measured, so these designs need to be robust across a range of potential thermal conditions.”

One of the major points here is that shortened product development cycles can occasionally result in design deficiencies. Situations like this have occurred countless times in the past, and laser peening has been recognized as a solution to treat critical areas that do not perform as intended.  Laser peening often enables these products to meet and exceed their original design requirements.

 

Whether you are looking at new designs that stand to benefit from laser peening, or you’re looking to improve upon your current product line, laser peening presents a great opportunity to increase your product reliability.  Give us a call to discuss your application!

 


LASER PEENING PATENT INFRINGEMENT LAWSUIT UPDATE

On July 2, 2012, Metal Improvement Company filed a third Request for Reexamination with the USPTO, again asking that the USPTO reexamine all of the claims of the ’876 patent in light of various printed publications submitted by MIC in the third Request. As expected, in November 2012, the USPTO issued a Notice of Intent to Issue a Reexamination Certificate, wherein the USPTO once again stated its intent to confirm all 38 of the claims of the ’876 patent in their originally issued form. As a result, all of the originally issued claims of the ’876 patent remain valid and enforceable.
