Adaptive Compliant Wing

From Wikipedia, the free encyclopedia

The Adaptive Compliant Wing is a wing design developed by FlexSys, Inc. which is flexible so that its shape can be changed in flight.

The wing design features a variable-camber trailing edge which can be deflected up to +/- 10°, so that it acts like a flap-equipped wing, but without the individual segments and gaps typical in a flap system. The wing itself can be twisted up to 1° per foot of span. The wing's shape can be changed at a rate of 30° per second, which is ideal for gust load alleviation.

The development of the Adaptive Compliant Wing is being sponsored by the U.S. Air Force Research Laboratory. Initially, the wing was tested in a wind tunnel, and then a 50-inch section of wing was flight tested on board the Scaled Composites White Knight research aircraft in a seven-flight, 20-hour program operated from the Mojave Spaceport.
