NASA successfully tests shape-changing airplane wings
The ACTE project is a
joint effort between NASA and the U.S. Air Force Research Laboratory to
explore technologies that will significantly reduce drag, structural
weight, and aircraft noise.
NASA has successfully tested a shape-changing wing design that could
do away with the conventional flaps seen on commercial airliners.
Since last year, NASA researchers have been conducting the tests in
collaboration with the U.S. Air Force Research Laboratory and
engineering company FlexSys Inc.
"The completion of this flight test campaign at Armstrong [Flight
Research Center] is a big step for NASA’s Environmentally Responsible
Aviation [ERA] Project," said the project's manager, Fay Collier. "This
is the first of eight large-scale integrated technology demonstrations
ERA is finishing up this year that are designed to reduce the impact of
aviation on the environment."
NASA first tested the wings last summer.
Researchers replaced the aluminum flaps that passengers are familiar
with from commercial airlines, and replaced them with "advanced,
shape-changing assemblies that form seamless bendable and twistable
surfaces."
“We are thrilled to have accomplished all of our flight test goals
without encountering any significant technical issues,” Air Force
Research Laboratory program manager Pete Flick said in a statement.
The "flexible trailing-edge wing flaps" have the potential to both
improve aerodynamic efficiency of airplanes, and reduce the noise
generated during takeoffs and landings, according to NASA.
As previous advances have shown, small changes in a plane's design can make a significant difference in energy efficiency.
The "sharklet" winglet design on some Airbus planes, for example, can save 4% on fuel.

NASA is working on other next-generation plane designs, including a new tail technology.
