    NASA is looking to save airlines millions of dollars by developing a series of new technologies, with the latest being a bug-repellant coating.

    NASA researchers have determined that bugs splattered on a commercial jet can can decrease fuel efficiency by as much as six percent, essentially disturbing the airflow over the surface.

    In order to conquer the messy situation, NASA is testing a new bug-repellant coating technology that utilizes non-stick materials resulting in bugs sliding right off of a plane.

    Boeing’s specially designed 757 ecoDemonstrator is in charge of testing NASA’s six different coatings at the moment, in order to determine which coating performs best.

    Yesterday, March 17th, Boeing successfully completed the initial functional check flight for its brand new 757 ecoDemonstrator, part of a collaboration with NASA’s Environmentally Responsible Aviation Project.

    The aircraft was specifically designed to test and evaluate new wing and tail technologies aimed at reducing drag and improving operating efficiency.

    European-based airline group TUI is also a major player involved in the project, responsible for providing the plane itself which is equipped with two wing state-of-the-art design technologies and an active flow control feature in the vertical tail.

    The wing tests will focus on the ability of a wing to maintain low-drag laminar flow by minimizing the insect strikes/residue that builds up along the leading edges.

    The active flow tests, on the other hand, will determine the best way to increase rudder effectiveness in order to enable future planes the ability to feature smaller vertical tails, lower weight, and lower drag, among other things.
