Title The New Age Of Stealth Is Arriving: Is This The End of The F-22? Media name/outlet Yahoo! News Media type Web Country/Territory United States Date 10/10/19 Description Researchers at BAE Systems and The University of Manchester successfully test-flew an experimental unmanned aerial vehicle with no moving control surfaces, BAE Systems announced in December 2017.
The 12-foot-span, jet-propelled MAGMA drone could help BAE develop stealthier warplanes. Control surfaces account for a significant portion of an airplane’s radar signature.
Instead of rudders, ailerons and other conventional control surfaces, MAGMA relies on two new technologies for maneuverability. Wing circulation control “takes air from the aircraft engine and blows it supersonically through the trailing edge of the wing to provide control for the aircraft,” according to BAE Systems.
Fluidic thrust vectoring, meanwhile, “uses blown air to deflect the exhaust, allowing for the direction of the aircraft to be changed.”
“These trials are an important step forward in our efforts to explore adaptable airframes,” Bill Crowther, leader of the MAGMA project at The University of Manchester, said in a BAE Systems release. “What we are seeking to do through this program is truly ground-breaking.”
