Groen Brothers Aviation was formed in 1986 by David Groen with brother Jay Groen, based in Salt Lake City, Utah. The company later changed names to Groen Aeronautics Corporation (now operating under the name Skyworks Global). Groen was founded as an autogyro research and development company, inventors of the “Hawk Gyroplane,” incorporating helicopter design components into autogyro design. Their design added helicopter-style collective pitch control, which allowed their aircraft to achieve vertical takeoff and landing and to stabilize flight at high and low speeds. (see attached photo of the Groen brothers with their Hawk 1 prototype ca. 1986)
The company holds three U.S. patents and several international patents associated with their variable pitch rotor system. Following the first flight of their proof-of-concept aircraft in 1987, the company flew several larger prototype autogyros during the 1990s. In September 1999 the company flew their first piston-engine powered prototype of the four-seat Hawk 4. The turbine-engined prototype first flew in July 2000, with a Rolls-Royce 250 420 hp turboprop engine and was the world’s first turbine powered gyroplane. The design's rotor blades used a company-developed natural laminar-flow airfoil.
In 2002, the company provided the Utah Olympic Public Safety Command (UOPSC) a Hawk 4 prototype for perimeter patrol around the Salt Lake City International airport during the  2002 Winter Olympics. The Hawk 4 completed 67 missions over 75 hours of flying time during the 90-day contract.
In February, 2003, the company introduced its “Stabilization Augmentation Kit,” designed to improve in-flight stability and safety for kit gyroplanes on the market. The company entered the kit market with the Sparrowhawk, later forming American Autogyro as a subsidiary to produce and sell Sparrowhawk kits as a separate business.
In November, 2005, the U.S. Research Projects Agency (DARPA) selected a company-led team to design a proof-of-concept high-speed, long-range, VTOL, GBA-DARPA Heliplane designed for combat search and rescue. The project was named the “Heliplane” by DARPA and intended to meet economy and performance goals not achievable by existing aircraft. The company completed work for Phase I of the project in 2009, but the project has not been further funded.
In December 2012, Steve G. Stevanovich led an acquisition of Groen Brothers Aviation by forming a new private company, Groen Aeronautics Corporation, which was registered in Delaware and acquired all the assets of the public Company Groen Brothers Aviation, Inc. This acquisition was accomplished in a transaction equal to more than 0 million. Groen Brothers Aviation Inc. retains a minority share holding in the Groen Aeronautics Corporation. Groen Aeronautics Corporation has since been re-branded as Skyworks Global Inc.
