LANGLEY, Va., Nov. 4 (UPI) -- NASA says its scientists are studying the effect insects have on aircraft performance, especially during takeoff and landing, in hopes of saying \"bug off.\" <\/p>\n
Bug splatter that coats aircraft surfaces can disrupt the laminar -- or smooth -- flow of air over an airplane's wings, creating more drag on the airplane and contributing to increased fuel consumption, they said. <\/p>\n
Researchers at NASA's Langley Research Center in Virginia have run a number of flight tests of airplane coatings that may one day reduce the amount of bug contamination on the wings of commercial aircraft, the agency reported Monday. <\/p>\n
A series of flights were made to put the coatings through takeoff and landing tests on a NASA aircraft. <\/p>\n
\"The reason we do these tests at low altitudes or do a lot of takeoffs and landings is because bug accumulation occurs at anywhere from the ground to less than 1,000 feet,\" materials researcher Mia Siochi said. <\/p>\n
In the tests, the coated surfaces were found to have fewer and smaller bug splats, she said. <\/p>\n
It will probably be some time before the coatings end up on commercial airliners, the researchers said, because the coatings have to be durable enough to withstand a lot of time in operation, and that will require further testing. <\/p>\n
In addition, Siochi said, the savings in fuel have to be enough to make up for the cost of applying the coatings. <\/p>\n
\"So we have to get through that hurdle of practical application of these materials,\" she said. <\/p>\n
