Kitty Hawk Moments: Mosquitoes...and Disappointment April 21, 2003 - Having
hired a man to run their bicycle shop, the Wrights were able to leave
earlier for Kitty Hawk in 1901. They arrived at their former campsite on
July 11, full of confidence based on their previous year’s testing –
and with a glider of the same design, but much larger, with a wing-span of
22 feet, and a weight of 98 pounds, nearly twice that of its predecessor.
Their mood was tested, however, when they were greeted by a foul
nor’easter with 93 mph winds, and forced to pitch their tent in the
pouring rain. Four days later, they began building a hangar big enough to
house their new glider, which Orville thought was “a grand institution,
with awnings at both ends…”
Two others, George Spratt
and Edward Huffaker, arrived shortly thereafter – invited as a favor to
Octave Chanute. Along with them came dark clouds of mosquitoes, which
chewed through the men’s clothes and left lumps like hen eggs all over
their bodies. At night they were forced to wrap up in blankets, with only
their nose showing, but then the wind would drop and they would sweat
unmercifully, forcing them to partially uncover, at which time the
mosquitoes would attack again. Finally, they gained relief by burning old
tree stumps next to their beds, preferring the smoke to the mosquitoes. On July 26, the new
glider was finished, but there were problems from the start. Wilbur got in
17 glides the following day, but the first went nose-first into the sand,
and although he did log one flight of 315 feet in 19 seconds, he was never
in control of the machine. Time after time it flew an undulating pattern,
often climbing out of control, only to stall dead in the air, forcing
Wilbur (who was lying on his stomach) to quickly scoot far forward to
force it down for a landing.
Pitch control was the
problem, but what was the answer? First the Wrights reduced the camber of
the wing (which was greater than that of the 1900 glider) to decrease
resistance and make the glider more responsive. They also reshaped the
leading edge spar and added a new spar near the midpoint of each wing. On
August 8, they were pleasantly surprised when Wilbur was able to soar 389
feet after just a few trials. The change in camber had solved the pitch
problem. Encouraged, they loosened the warping cables, expecting it would
give them complete control. What happened was just
the opposite. For whatever reasons, the machine began turning and skidding
sharply. On August 9, when the left wingtip dropped, Wilbur shifted to the
right, and the craft darted down into the sand, throwing him forward
through the elevator. The forward surface was badly damaged and Will
suffered bruises to his nose and eye. Disheartened, the Wrights returned
to unmanned tests, but all the flights were less than 200 feet. The tests
confirmed the existence of a problem, but no solutions. On August 22, they
left for Dayton. The new difficulty with lateral control was disturbing,
and they now realized there was some mysterious problem with the
wing-warping system they could not fathom. “When we left Kitty
Hawk at the end of 1901,” Wilbur recalled a decade later, “we doubted
we would ever resume our experiments.” Orville’s memory was of his
brother’s exasperation on the long trip home, when at one point he had
remarked: “Not within a thousand years would man ever fly!" |
