One Hundred and Eleven Years Ago Today...

DAYTON BOYS SOLVE PROBLEM
WILBUR AND ORVILLE WRIGHT SUCCESSFULLY OPERATE A FLYING MACHINE IN NORTH CAROLINA

Those were the headlines the day after Orville Wright flew a heavier-than-air flying machine a distance of 112 feet over the sands of Kill Devil Hills on the Outer Banks of North Carolina.

December 17, 1903

On December 14, 1903, after winning a coin toss, Wilbur made a three second flight attempt, stalling after takeoff and causing minor damage to the flyer. Three days later, having repaired damages, they made history with four successful flights. The first was a twelve second flight by Orville; the last flight by Wilbur covered 852 feet and lasted 59 seconds.

3-Axis Control - one of three major break-throughs
Wilbur and Orville Wright had been scientifically experimenting with the concepts of flight since 1899. They based the design of their kites and full-size gliders on work done in the 1890's by other aviation pioneers. In 1900, the brothers traveled to Kitty Hawk, North Carolina to begin their manned gliding experiments. They made over a thousand flights from Kill Devil Hills in their gliders. The fundamental breakthrough was their invention of three-axis control, which enabled the pilot to steer the aircraft effectively and to maintain it's equilibrium.

A Lightweight Engine
Besides 3-axis control, another key development for a heavier-than-air flying machine was a lightweight engine. Their shop mechanic, Charlie Taylor, built them an engine in just six weeks. To keep the weight low enough, the engine block was cast from aluminum, a rare practice for the time.

The Third Break-through... Propellers
Their library research on propellers disclosed no established formulae for either marine or air propellers, and they found themselves with no sure starting point. After much debate they concluded that an aeronautical propeller is essentially a wing rotating in the vertical plane. On that basis, they used data from miniature wind tunnel tests to design their propellers; two contra-rotating blades (no torque) to push the plane, rather than pull it through turbulent prop-wash. Wilbur made a March 1903 entry in his notebook indicating the prototype propeller was 66% efficient. Modern wind tunnel tests on reproduction 1903 propellers show they were more than 75% efficient under the conditions of the first flights, "a remarkable feat", and actually had a peak efficiency of 82%.

Were the Wright Brothers First?
There are many who say the Wright Brothers weren't the first to fly a heavier-than-air machine successfully. Supporters of the post-Wright pioneers argue that techniques used by the Wright brothers disqualify them as first to make successful airplane flights. Those techniques were: a launch rail; skids instead of wheels; a headwind at takeoff; and a catapult after 1903. Supporters of the Wright brothers argue that proven, repeated, controlled, and sustained flights by the brothers entitle them to credit as inventors of the airplane, regardless of those techniques.

Me? I'm pro Wright Brothers... but regardless, it was a magnificent feat by... well, you finish it.

If your journeys take you to the east coast, why not plan to visit the Wright Brothers National Memorial, run by the National Park Service.

What the Wright Brothers achieved changed the world forever... and being a pilot, I am forever grateful, for up there in the air... well, it's just a magical place to be.

I'd like to acknowledge Wikipedia for much of the research I did for this entry. If you'd like to know more about the Wright Brothers and other manned flight pioneers, here's some links you can follow:

The Zen Glider... Single-line Indoor Kiteflying at it's Best

I have watched this video countless times, and it still gives me goose bumps. The music, "Once Upon A Dream (Lisa)," is so appropriate, and Daryl Yeh has such incredible control of his Zen Glider. The end will give you shivers... at least it does me.


And if you enjoyed that video, you'll like this next one. You may think the video was shot in slow motion, but it was not; the Zen Glider flies ever so slowly.

The Melodious Flute Kites of Vietnam

The Vietnamese make kites with flutes attached; that way the kites make music while flying. When the sky is full of flute kites, it's like a symphony-in-the-sky.

Multiple flutes create a harmonic sound

Here's the sound of one flute kite with eleven flutes:


...and here's the sound of many flute kites in the air... and the happy sounds of kitefliers & their families:

The 1st Sunday of November was great kite weather!

Sunday left nothing to complain about unless it was the loss of an hour of daylight at the end of the day (fall back). Jim Stainback and I arrived at Wildwood Park about 11:30 AM and while we were putting up banners Rhonda Davidson and Mike Hagen showed up. By noon we had several single-line kites in the air. Winds for the afternoon were in the range of 11-14 mph out of the NW to NNW (good 'ol Chico wind bouncing off the foothills).

Unfortunately I was so into flying I didn't get out my camera until Mike suggested we set up my Goblin 6-pack and have some two-line fun.

Here's Mike flying my stack of Goblins

If I can get any photos of our single-line kites I'll add them to the post.

COME FLY A KITE WITH THE CHICO KITEFLIERS

Sunday November 2nd is the first Sunday of the month. In Chico that means gathering at Wildwood Park for a day of kite flying. Join us if you can.

Strong North Winds... Big Boy loved it!

Fellow kiteflier, Jim Stainback picked me and my kites up around 11 AM, and off we went to Wildwood Park in Chico. Winds were cranking at 15 to 22 mph out of the NNW with clear skies and temperatures in the upper 60s... great fall weather for kite flying. We had kites in the air by noon.

For me, one of the joys of kite flying is sharing my hobby with others. So many people at the park come up and thank us for flying our kites. I love watching all the other people smiling and pointing or showing their kids the kites.

We flew until after 4 PM and then packed it in. Jim and I gave the day a 9.5. Until next time...
