The Company’s history reflects continuing study and increasing understanding of the technology underlying the science of autorotative flight, the primary characteristic of gyroplanes and gyrodynes. Since the designs of an airfoil specifically for autorotation and the first patented variable pitch rotor system for gyroplanes, over the years, our accomplishments have been demonstrated by over 60 awarded and pending patents in these fields. Today, GAC is widely recognized as the leader in autorotative technology.

GAC’s principal research and development objective is to advance the industrialization of its autorotative research to date. However, research is continuing into achieving much greater capabilities of gyroplanes and gyrodynes through exploitation of the Company’s knowledge and patent rights.

  • The use of new software and hardware to further increase understanding of the behavior of rotor systems to optimize design so as to both increase aerodynamic efficiency and operating life in relation to an aircraft’s mission
  • The application of new materials for rotor blade design and manufacture using both standard composite technology, as well as new high temperature composites
  • The examination of the utility of new engines, advanced avionics and other innovations by aviation industry suppliers
  • The application of the scalability benefits for gyroplanes and gyrodynes versus other rotorcraft
  • The utility of the much simpler mechanical designs of autorotative aircraft versus powered-rotor aircraft in the design and manufacture of aircraft for unmanned missions (UAVs)
  • The potential for vertical take-off and landing (VTOL) and ultra-short take-off and landing (USTOL) commercial airliners ranging in size from 19 to 100 passengers, or equivalent freight, that do not need runways and with cruise speed up to 300 knots can achieve the trip times of regional jets.

These research and development programs will continue to ensure GAC keeps abreast with developments in key aviation fields while continuing its long-term mission to expand the frontier of autorative technology.
