Air International 2012-08 / C.Kjelgaard - Environmentally Responsible Engines /Technology/
As a major early goal of the ERA project, NASA funded studies by Boeing, Lockheed Martin and Northrop Grumman of advanced subsonic transport aircraft. Lockheed Martin's concept a box-wing, biplane-like design with both swept-back and swept-forward wing sections, which were joined at their tips by vertical surfaces, was - in some ways - the most imaginative of all three designs. It relied on advanced composite materials and structures - for which the manufacturing technology has not been available until recently - to make its wing structure light enough to obtain the fuel-burn benefit that NASA's Advanced Vehicle Concept targets demanded.

Three concepts produced for the Environmentally Responsible Aviation project by Boeing (left), Lockheed Martin (right) and Northrop Grumman (rear). All feature different configurations, with Boeing studying a blended wing body, Lockheed Martin a boxed wing and Northrop Grumman a flying wing.
