When the Society hears of the Wright Brothers’ logical approachto overcoming the 1901 disappointments and their successfulwind tunnel trials, excitement builds about human flight.Arrangements are again made for you to resume your positionas a lookout with the Kill Devil Lifesaving Station. Your friendsat the station are glad to see you again.At the end of August the Wrights arrive and rebuild their camp.When they uncrate and assemble their glider, it is indeed achanged machine. The wingspan has grown to 32 feet and thewidth has been decreased to 5 feet. A control device called aTesting the 1902 Glider.“hip cradle,” which the pilot operates by moving his hips,controls the wing-warping. The front rudder has been modified to look more like a wing. In addition, a tail withtwo 6-foot-high vertical tails has been added. On your first visit, Orville explains that they are hoping the tailswill give the pilot more control in turning. You help to carry the craft up the hill—it weighs a good 120 pounds.The glider flies wonderfully, much better than the one last summer. A new problem, however, soon arises. Inabout one flight in fifty, the glider spins out of control and crashes after making a turn. The brothers makeseveral adjustments, but nothing seems to help.When you return in a few days, the brothers have removed the two vertical tails and replaced them with just asingle tail. Wilbur has also rigged the tail to the hip cradle control that warps the wings. Now when the pilotshifts his hips to bank, the tail also turns. “Orville reasoned that in low-speed turns, the tail was acting like avertical wing, providing a sideways force that caused the glider to spin,” said Wilbur. “I thought up how to rig thewing-warping to the tail-turning.” That’s just one example of how the two brothers thought and worked so welltogether.Activity 13—Build a Model of the 1902 GliderWhen Wilbur takes off, your jaw drops. The glider banksleft and then right, rises up and down on command, andthen glides to a smooth landing. They’ve done it! Thebrothers have achieved complete control in the air.You’re watching the first machine in history that can becontrolled in three dimensions: pitch, yaw, and roll.Over the next few weeks, the brothers make severalhundred glides, becoming better and better at controllingtheir craft. You are sending glowing letters back tothe Society and helping Orville develop some of thepictures he has taken. The brothers feel that they onlyneed to add an engine and propellers and they willbecome the first in the world to fly a powered aircraft.To make a model of the 1902 Glider, follow the instructions beginning on page 55.Learning to Fly: The Wright Brothers’ Adventure EG–2002–12–007–GRC25
Activity 14—Compare the 1900, 1901, and 1902 GlidersBelow are drawings of the gliders the Wright Brothers tested in 1900, 1901, and 1902. Notice that WilburWright is the same size in all three, which means all three are drawn to the same scale.1900 190119021. Try to list five ways in which all the gliders are alike.2. What are some of the ways that they are different?3. The 1901 and the 1902 gliders both have about the same wing area and they weigh nearly the same. Why doyou think the 1902 is a better glider?4. Notice that in all three gliders, Wilbur is lying down. What do you think the effect would be if he sat up whileflying them?Learning to Fly: The Wright Brothers’ Adventure26EG–2002–12–007–GRC
