An Eye for Design
Lockheed Martin’s products have life-spans measured in decades, so long-term sustainability is imperative. It begins with design. We take an integrated approach that extends from suppliers to the production line to maintenance and disposal.
Dozens of material-substitution projects aimed at pollution prevention and life-cycle cost avoidance are introducing a range of new technologies, including chromate-free paints and sealers to cadmium-free electrical connectors. By focusing on EESH-friendly source materials, products and process by-products that can be reused or recycled, we reduce or eliminate potential pollutants that may be detrimental to our health and the environment.
When designing for sustainability, customers are seeking renewable-based energy solutions that lack a logistics footprint. Case in point …generator sets (gensets) on the battlefield. The gensets we produce for the Department of Defense (DOD) consume large amounts of fuel, and delivery of fuel is both expensive and dangerous. So, we are engineering more efficient gensets that will reduce costs and help keep our troops out of harm’s way.
C-130 Fuel Savings
Our Aeronautics’ C-130 Program is pioneering key technologies that provide fuel savings for the aircraft fleet. By incorporating micro-vanes into the fuselage, our engineers improved system performance by reducing drag by 3.7% and reducing fuel consumption by 2-3%. These modifications will save approximately 20 gallons of fuel per aircraft flight hour. With the DOD operating 355 C-130 aircraft, each with approximately 600 flight hours per year, this equates to an annual savings of over $10 million in fuel costs.
Design for Advanced Environment, Safety and Health Training
Every two years, our aeronautics materials engineers participate in this training, which covers hazardous material management and recordkeeping, identifying alternatives for restricted materials, properly classifying cleaners and coatings, and updates on Lockheed Martin’s technical policy on expanding the use of non-chromate containing products.
F-35 Case Study
We responded to the call to reduce environmental impacts before, during and after construction of the F-35 Lightning II.
Lockheed Martin F-22 Raptor
Key maintenance enhancements of the Lockheed Martin F-22 Raptor include a completely electronic diagnostic system that provides a paperless approach for all troubleshooting and maintenance. The Pratt & Whitney F119 engines are designed to allow standard flight line maintenance using just six common tools available at commercial hardware stores. Strategically placed access panels, along with access points in the landing gear wells and weapons bays, make the Raptor easier to arm, fuel and maintain while avoiding the need to disturb the low-observable coatings.
Solid Oxide Fuel Cells
Lockheed Martin’s Mission Systems and Sensors (MS2) recently completed testing of Solid Oxide Fuel Cells (SOFC), an alternative energy solution that efficiently converts fuel into electricity using a chemical reaction, unlike the combustion engines used in today’s diesel gensets. SOFC systems are cleaner, 30-50% more fuel efficient and more cost-effective than existing military gensets. They use nearly half the fuel currently required, potentially saving billions of dollars while protecting our troops and cutting carbon emissions.
