GBA-DARPA Heliplane
Encyclopedia
With funding from the U.S. Defense Advanced Research Projects Agency
(DARPA), Groen Brothers Aviation
(GBA) is designing a proof-of-concept, long-range, vertical takeoff and landing aircraft intended to cruise at twice the speed of conventional helicopters.
DARPA’s objective is to achieve performance with a rotary-wing aircraft comparable to that of a fixed-wing plane. The concept combines technical aspects of a gyroplane, which GBA has been working on since the late 1980s, with a fixed-wing business jet.
The work is part of a multi-year, $40-million, four-phase program. GBA—along with Georgia Tech, Adams Aircraft Industries, and Williams International—worked on Phase 1 of that program, a 15-month effort funded at $6.4 million. Phase 1B of the program will be managed by Georgia Tech, using GBA as a subcontractor. Phase 2 development includes a “subscale wind tunnel demonstration in the high-speed, high-altitude wind tunnel at NASA Langley and the building of a full-scale tipjet nozzle. Phase 2 is anticipated to be a substantially bigger undertaking (valued at $24-28 million).”
