Skip to comments.Aviation history is made by 'flapper'

For an aeronautical engineer it was the perfect day and a perfect end to a quest that has consumed his life for more than 30 years.
Yesterday Dr. James DeLaurier, an aeronautical engineer and professor emeritus at the University of Toronto's Institute for Aerospace Studies, fulfilled a lifelong dream, seeing his manned mechanical flapping-wing airplane, or ornithopter, fly a dream first imagined by Leonardo da Vinci.
And with the successful flight DeLaurier has been lucky enough to touch what many describe as the Holy Grail of aeronautical design, achieving a place for himself, his team of volunteers and students in aviation history.
The flapper, as it's affectionately known, sustained flight over about a third of a kilometre for 14 seconds at about 10:20 a.m. before being hit by a crosswind and almost flipping over, damaging the nose and front wheel on the runway at Downsview Park.
But the flight was long enough to prove DeLaurier's mechanical flapping-wing design for a manned, jet-boosted aircraft works. The successful test flight was longer than the first powered flight by aviation pioneers the Wright brothers in December 1903 that lasted 12 seconds over a windswept beach in North Carolina. Beating that record was enough for DeLaurier.
"It is a perfect day," he said after the flight. "If I have the big one now, I'll die happy."
After four attempts at getting the ornithopter in the air, the fifth brought glory. The ornithopter, which looks like a cross between an old-fashioned plane and a Canada goose, took off and flew about two metres in the air. DeLaurier whooped and hollered from a truck by the side of the runway, watching it with complete wonder and joy.
"You did it man," he told pilot Jack Sanderson. "You've made an old professor really happy," DeLaurier said as he hugged him, choking back tears. "You've made aviation history." Then DeLaurier matter-of-factly walked down the runway to find a wing tip that broke off during the hard landing.
The team walked the ornithopter quietly down the runway to the hangar.
Like many aeronautical engineers and scientists before him, DeLaurier has long puzzled over the idea of mechanical flapping-wing flight. Indeed, the search for a perfect flapping-wing airplane is, for aeronautical engineers, like mathematicians' quest to solve Fermat's Last Theorem fuelled by an insatiable hunger for knowledge.
"I hadn't planned on this taking most of my career, but I don't regret it," said DeLaurier. "It has been exciting and interesting. Also it's been a worthy project, a worthy quest. You know that age-old saying: `What's the meaning of life?' Quite frankly, life has meaning if you measure yourself against a worthy goal. And for an aerospace engineer who loves aviation history this has been a worthy goal."
Humanity has always been fascinated by the idea of man flying like a bird. The Greeks told mythic tales about Daedalus and Icarus who fled the Labyrinth on wings of wax and feathers. Da Vinci was so fascinated with the idea he conceived an elaborate plan for an ornithopter a design that, DeLaurier said, would never fly because the materials would be too heavy.
And so DeLaurier was moved to build what many have thought impossible a manned engine-powered, flapping-wing airplane that would take off unaided. As a teenager DeLaurier was consumed with that dream, playing with rubber band-model ornithopters that he made out of balsa wood. But he didn't get serious about the quest until 1973 when he met Jeremy Harris, a principal researcher and colleague at Battelle Memorial Institute in Columbus, Ohio. The two became inseparable, working on the ornithopter.

to test pilot Jack Sanderson
I would stand clear of those wings.
LOL, I would stand clear of the whole plane.
The new Airbus 350?
(Although...the same was said about the Wright bros....LOL)
If we could just add pedals
Atreides that is.
See post #8.
Think I'll stick with the fixed wing thanx.
I miss the reference?
Imagine this thing perching above the car you've just washed.
Apropos, the trashbag flyer.
