The Synergy Aircraft Synergy is a proposed five-seat, single-engine, kit aircraft, designed by John McGinnis of Kalispell, Montana and intended for production by his company, Synergy Aircraft.[1][2][3]
The aircraft's closed wing design, termed a "double box tail", is intended to lower induced drag and be stall resistant, along with boundary layer control methods.[2] Many of the details are disclosed in US patent 8657226.
Design and development
Development was started in 2010 to develop the Synergy as a future kit airplane. The Synergy is the first aircraft that was designed to use the 200 hp (149 kW) DeltaHawk V-4 engine. An electric-powered 1/4 scale version of the aircraft has been built and flown via radio control.[2]
The Synergy design was unveiled at the 2011 CAFE Foundation electric aircraft symposium.[4] The aircraft was intended to compete in the 2011 NASA/CAFE Green Flight Challenge,[5] but its funding and engine were delayed, forcing the team to withdraw from the competition.[6]
After receiving the DeltaHawk engine in December 2011 work resumed and a funding drive was launched to complete the prototype. Intended as a Kickstarter crowdfunding project, the initial project application and appeal were rejected on the basis of not fitting in with Kickstarter's creative arts focus.[7] On 13 May 2012, however, Kickstarter informed McGinnis that they had reconsidered and that the project was approved.[8] The project raised US$95,627 gross funds.[9]
By mid-December 2012 McGinnis indicated that the Kickstarter campaign had raised US$80,000 and that he was intending to have a flying proof-of-concept aircraft at AirVenture 2013. He also stated that if the aircraft is not complete then he will not have a display there. The Kickstarter campaign also attracted a lot of interest, but answering email and phones calls has slowed work on the prototype down.[10]
