History

In 2014, Barry Jones and James Robb teamed with EPM Technology to launch the civil Bulldog project, having been earlier unsuccessful with design of a military turboprop autogyro, the Gyrojet Scorpion. Following receipt of funding (£200,000 loan and £95,000 grant) by the Derby Enterprise Growth Fund, headquarters were established in that city in October 2014, with Tatenhill aerodrome selected for flight testing. The prototype was publicly unveiled at Aero '15, Friedrichshafen, 15 to 18 April 2015, and an initial production target of 20 per year by workforce rising to 30 was predicted. In July 2015, BJJR announced there had been discussions with a major manufacturing company with the consideration of forming a partnership for the production of the Bulldog and other autogyro variants. The maiden flight was expected in January 2016, but this deadline has been missed and the project appears to be no longer active.

Barry Jones and the EPM company are among others involved in Chimera Dragon autogyro project, launched in July 2016.
