FlexFoil Wing Tests Peaking


Kissimmee, Florida — In the midst of the most grueling set of flight-testing its FlexFoil Variable Geometry Control Surface has ever been subjected to, FlexSys, Inc. is exhibiting its technologies at the American Institute of Aeronautics and Astronautics (AIAA) SciTech 2015 Forum in Kissimmee, Florida. FlexSys staff will be on hand to demonstrate our concepts and provide current updates on the flight-testing progress of our Adaptive Compliant Trailing Edge (ACTE) test program that is currently being conducted at Edwards Air Force Base in Mojave, California.

The series of ACTE tests began in late October and the first flight test took place on November 6th over NASA’s Armstrong Flight Research Center. NASA and the U.S. Air Force Research Lab are jointly conducting the ACTE program to prove the airworthiness of FlexSys’ FlexFoil technology for optimizing fuel efficiency as well as reducing air loads and airframe noise. To date the tests have subjected these new control surfaces to speeds in excess of 0.75 Mach at 20k to 40k ft. altitude, hard banking maneuvers up to 1.7G (continuous load), and high dynamic pressures up to 384 psf. So far the test pilots describe the new wing as “very smooth” with zero concerns about its performance or material condition.

These and previous tests have proven that the 22-foot long seamless FlexFoil variable geometry surfaces on both wings of a modified Gulfstream GIII are as strong or stronger than any conventional design while still maintaining their unique flexibility. The FlexFoil™ surface is capable of changing wing camber from -9 to +40° on demand as well as being able to twist span-wise along the trailing edge up to 30° per second. Using aerospace grade materials, the shape-changing surface is able to withstand temperature changes from-65°F to 180°F, harsh chemicals, and fatigue cycles beyond the standard commercial aircraft lifetime. Even so its internal mechanism has no joints to wear out.

FlexSys personnel are on hand at SciTech 2015 to also help you understand how our FlexFoil™ technology can be applied to any structure interacting with a fluid medium including flight control surfaces, engine inlets, turbines, rotor blades, underwater surfaces and other wind energy, automotive, aerospace and marine applications.
