Synergy Aircraft Synergy
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]
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.[3] The aircraft was intended to compete in the 2011 NASA/CAFE Green Flight Challenge,[4] but its funding and engine were delayed, forcing the team to withdraw from the competition.[5]
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.[6] On 13 May 2012, however, Kickstarter informed McGinnis that they had reconsidered and that the project was approved.[7] The project raised US$95,627 gross funds.>
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.[8]

The highly aerodynamic and fuel-efficient ‘synergy’ aircraft utilizes an innovative ‘double-box tail’ structural design
The ‘synergy‘ personal aircraft being developed under john mcginnis combines decades of aeronautical innovation into a single, highly aerodynamic and fuel-efficient airplane design, including a custom-designed ‘double-box tail’. a 1/4-scale carbon fiber model has already been tested, and with funding permitting the development team intends to build a full-scale prototype beginning late 2012 into next year.
2011 test fly-by of the scale model
based on the scale model testing and calculations, the design is reported to achieve about forty miles to the gallon, ten times the fuel economy of conventional small jets, at ten percent of the cost. in addition to using biofuel and the experimental deltahawk turbocharged engine, it combines six innovations in drag reduction*, characterized most evidently in its double-box tail wherein a vertical winglet connects the tail and wingtip on each side (not to be confused with the more conventional but fuel-inefficient double-box wing design). ‘synergy’ also includes a ballistic parachute and push-button landing system in cases of emergency.
‘all of the major drag reduction breakthroughs of the last 100 years have been underutilized in aircraft design. and what we’re trying to do with ‘synergy’ is to use all of them in the most intelligent way that we can.‘ – john mcginnis
*mcginnis lists the six innovations considered towards the design as: laminar flow, non-planar configuration, wake-immersed propulsion, open thermodynamic cycle, pressure thrust, and optimum volumetric displacement waveform
with the design and model already approved by the FAA, the development team plans to build a full-scale prototype to be tested by the organization, before initiating a program seeking commercial production. they estimate that their final plane would have a maximum speed of between 100 to 450 mph, with a range of 500 miles.
from a piloting family of several generations himself, mcginnis notes that a major design concern in developing the ‘synergy’ is that the airplane be comfortable for non-pilots, an aspect neglected by conventional small personal planes. as a result, the aircraft is designed to comfortably seat five (although mcginnis notes it could be as high as seven).
mcginnis has launched a kickstarter campaign through june 4th to help fund continuing development costs.

Synergy Aircraft Project
We're building an airplane, in a garage (!) but it's not just another tired old airplane. This is Synergy, the beginning of the future.
