Boeing has begun several months of flights with its ecoDemonstrator 757 to evaluate new technologies to improve commercial aviation’s efficiency, reduce noise and carbon emissions. Boeing is collaborating with TUI Group and the National Aeronautics and Space Administration (NASA) on ecoDemonstrator 757 tests. The 757 flight tests continue the ecoDemonstrator Program’s multi-year effort to accelerate testing, refinement and use of new technologies and methods that can improve aviation’s environmental performance. On the left wing, Boeing will evaluate technologies to reduce environmental effects on natural laminar flow as a way to improve aerodynamic efficiency. As an example, the ecoDemonstrator 757 will test a Krueger shield that can protect the leading edge from insects. Boeing is under contract with NASA’s Environmentally Responsible Aviation (ERA) Project to test two technologies on the ecoDemonstrator 757. On the right wing, NASA will test bug-phobic coatings to reduce the residue left by bug strikes on the leading edges of aircraft wings; the goal is to enable more drag-reducing laminar flow over the remainder of the wing. On the vertical tail, NASA and Boeing are testing active flow control to improve airflow over the rudder and maximize its aerodynamic efficiency. Based on wind-tunnel testing, active flow control could improve the rudder’s efficiency by up to 20% and may allow for a smaller vertical tail design in the future. TUI Group, the world’s largest integrated tourism group, is collaborating with Boeing as a way to reduce carbon emissions. The Europe-based company, which includes six airlines, is preparing for a low-carbon future by reducing its environmental impact and encouraging its suppliers and customers to do the same.
