John McGinnis thinks ordinary families would rather skip the airport
and fly themselves. So he is trying to reinvent the personal airplane
with the help of his father, son, and a rotating crew of about two dozen
volunteers. Unlike small aircraft today—which can cost more than a
house—McGinnis says Synergy could be cheaper, quieter, and, at more than
40 mpg, three times as fuel-efficient.
McGinnis, a 47-year-old composite manufacturer, flew his first
airplane in second grade. Perplexed by the inefficiencies of personal
aircraft, he taught himself aeronautical engineering and fluid dynamics
over two decades. One day, while perusing scientific studies at a desk
in his daughters’ bedroom, he read a NASA researcher’s paper challenging
a classic aerodynamic drag equation. McGinnis could see the
possibilities. “I came out of the girls’ bedroom ranting like a madman
to my wife,” he says. “ ‘Honey, you’re never going to believe this. I
think I just solved a problem I’ve been working on since I was a little
kid.’”
Synergy’s wings bend upward and into a box shape for minimum drag and
maximum efficiency. The top half of each wing swoops behind the body to
function as a tail while providing greater in-flight stability. The
double-box tail design also makes gliding easier by counteracting
tornado-like vortices at the wings’ tips. And instead of a front-mounted
propeller, an impeller placed behind the bullet-shaped body quiets
noise while adding thrust.
