 The 22nd v2.0 PODCAST

December 2010 Episode: Orientation Rides

 1903 would become a year for the history books. That year the Wright brothers, Orville and Wilbur Wright, would fly the first powered, controlled, heavier-than-air airplane at Kitty Hawk, North Carolina on December 17, 1903. 1Most people don't know that it was not in 1903, but in the 1800s, that the Wright brothers, working with kites, had worked out the key issue for flight: control.

While other aviators searched in vain for "inherent stability," Orville and Wilbur created a method for the pilot to control the airplane. The real breakthrough was their ingenious invention of "wing-warping." If the pilot wanted to bank a turn to the left, the wings could be warped to provide more lift on the wings on the right side of the biplane. The brothers worked out a system for 3-axis control that is still used today on fixed-wing aircraft: left and right like a car or boat (a rudder), up and down (the 1903 Wright "Flyer" had its elevator in the front), and banking a turn as birds do (or like leaning to one side while riding a bicycle). Working with kites in 1899, the brothers figured out and tested their systems for 3-axis control, and in the next two years did experiments with gliders at Kitty Hawk, and then with their wind tunnel, to find the proper lift. They found that the formula for lift - namely the "Smeaton coefficient" that everybody had been using for over 100 years - was wrong. By the time they built their 1902 glider, they had worked out all the problems and they knew it would fly. The 1902 glider was actually the first fully controlled heavier-than-air craft, and some historians believe it was the main invention - essentially the invention of the airplane - and more important than the 1903 biplane. So it was on March 23, 1903 - nine months before the famous first airplane flight of December 1903 - that Orville and Wilbur Wright filed a patent application for a "Flying Machine." The patent was awarded May 22, 1906. That's when the aviation world started to copy the Wright's designs, and from that point remarkable progress was made in the development of powered flight.

The next step from the 1902 glider was powered flight. Like everything else the Wright brothers did up to this point, they applied a scientific method: break bigger problems down into smaller ones, study as much as possible what people have discovered before, understand the principles and the theory behind the particular problem you're trying to solve, and do some experiments to work out the particulars. For powered flight the main problem was understanding how propellers work. This was harder than it seems, as no one really understood that a propeller was nothing more than a wing that rotates on its axis, and lifts the plane forward. So, the Wrights turned to the ship-building literature and discovered that empirical principles were used, but there was no theory of propulsion. They then reasoned out the basic mental model of the propeller as a moveable wing. This allowed them to test propeller shapes in their wind tunnel, discovering an efficient shape. For their 1903 plane, they needed all the efficiency they could get.

To drive a propeller, you need a powerplant. The Wrights wanted a lightweight gasoline engine that would provide the necessary oomph. They tried to buy an engine, but no one was willing to build one to their specs. So, with the able assistance of Charles Taylor, they built their own. It was a state-of-the-art four-cylinder model. Taylor hand-tooled the crankshaft on the Wright shop lathe. Its power-to-weight ratio was better than anything around. Even still, in the words of Charles Taylor, "It weren't much of an engine." There was no carburator. The raw gas was just dumped into the cylinders. It was air-cooled, without even the benefit of fins. To control the engine speed, the spark could be advanced or retarded. It had the horsepower - barely - to drag the 1903 machine into the dense December ocean air. As the engine broke in the next year, it began to produce more horsepower, and better flights.

On Monday, December 14, 1903, when both the Wright flyer and the wind were ready, the brothers decided that Wilbur would take the first turn as pilot for the historic flight. Some readers might suppose that this was because Wilbur was older, or because he had taken the early lead in the project (though later there was an equalization), or perhaps because of some difference in piloting skills. It was none of these. It was decided by flipping a coin. They and the ground crew (5 lifeguards from the beach) had lugged the plane weighing six hundred pounds 1/4 mile to the big hill, laid out the 60-foot monorail, and were ready to go. After an initial problem getting it unhooked because of the slope (and the force from the propellers), the plane accelerated down the track so fast that Orville, running alongside to steady the wing by holding on to an upright, couldn't keep up. Wilbur turned the sensitive rudder up too sharply, the flying machine nosed up, slowed, came down in that position, and the left wing hit the sandy hillside and swung the plane around, breaking several parts. Although they didn't consider this a real flight, they now knew it would work.

Two days later, repairs had been completed, but the wind wasn't right. The following day, Thursday, December 17, 1903, would be the historic day. They realized it would be better to lay the track on flat ground. That and the strong (22-27 m.p.h.) winds meant that Orville (whose turn it was to pilot) was riding the plane along the track, at a speed that allowed Wilbur to keep up easily, steadying the right wing as Orville had done 3 days earlier. Just after the Wright flyer lifted off the monorail, the famous picture was taken, possibly the most reproduced photograph ever, which Orville had set up (having asked one of the men simply to squeeze the shutter bulb after takeoff). The flight wasn't much - 12 seconds, 120 feet. But it was the first controlled, sustained flight in a heavier-than-air craft, one of the great moments of the century.

The brothers flew 3 more times that day, covering more distance as they got used to the way the large front "rudder" (the elevator) responded in flight. Orville's second flight was 200 feet, and Wilbur's before it nearly as long. But the final flight of the day carried Wilbur 852 feet in 59 seconds.

 Congratulations to the CyberPatriot team for the great news clip on News14 Carolina (a statewide newscast).

We did not advance to Orlando, but the competition was much greater this year and with many more teams.  We are very proud of our CyberPatriot participants, the coaches and everyone that helped in the endeavor.  There is always next year!!!!

"This is what our nation is becoming, so this is not only helping you for high school or just having this knowledge, it's setting you up for the rest of your life,” student Josh Jordan said.

 Burlington, NC (Oct. 23, 2010) -  The CyberPatriot III  first round competition began at 10:00am, on Saturday, October 23rd for the greater than 660 teams registered in the world’s largest cyber-security competition, produced by the Air Force Association, a nonprofit organization near Washington, D.C.

This year’s competition has been increased over the last two years due to the AFA creating a new open division, designated for high school teams. This is  in addition to the previously established all-service division, comprised of teams from Junior ROTC and Civil Air Patrol squadrons throughout the United States.  

Teams surviving early online battles will vie again in a series of rounds to determine finalists for an all-expenses-paid trip to Washington, D.C., and the championship round at the Gaylord National Convention Center in April 2011.

As the Civil Air Patrol’s Burlington Composite Squadron team, dubbed the WiFi Warriors, began the competition, they soon realized that the battle would not be without its own cyber-glitches.  First Round real-time registration was not cooperating, causing the WiFi Warriors to actually begin working on the cyber-threats greater than one hour later of the official start time.   A problem with live scoring was soon discovered during the live competition, leaving the competitors wondering if their work would be counted.  

Even with the glitches, Wifi Warrior’s Coach, Captain Todd Lavinder, remained calm and focused on the threat-tasks at hand.  “I am not overly concerned with these glitches.  It is no wonder that these problems could occur with the numerous amount of  teams competing online at the same time.  We encountered the same type of problems with last year’s competition and the officials made good with advancing teams,” stated Lavinder.  The official correction advanced the Burlington team to the next round and subsequently, to the National Championship Round in Orlando, Florida, where they took second place overall and finished the highest of any Civil Air Patrol team in the competition.  

Soon it was evident that Capt. Lavinder was correct in his assumption when a status update was posted on the official CyberPatriot III website, allowing for one hour extra in the competition.  Later, after the competition ended, a formal statement was posted on the website.  “We apologize for the registration problems teams experienced today. We have been working with our partner SAIC to resolve the issues, but we are aware that the technical challenges impacted your ability to fairly compete. As a result, we are doing two things:
1) Every team will be automatically advanced to the second round of competition on November 6th.
2) Those teams who successfully competed will be carefully screened based on performance. Several of those teams, based on exceptional performance, will be advanced directly to the third round of competition on December 4th.
Details will follow. We apologize for the frustration. We are committed to improving for the next round as we trust you are to competing,” as written by CyberPatriot Commissioner, Bernie Skoch.

“Hopefully, the fact we kept calm and focused on the actual tasks given to us , not the system problems we encountered, we will advance to Round 3 of the competition,” stated Lavinder. “I feel confident. We have an excellent team assembled, comprised of many of last year’s members.”
