1902 Wright Glider (reproduction)
The third in a series of gliders leading up to their powered airplane, the 1902 glider was the Wright brothers' most advanced yet. Reflecting their single, evolving design, it was again a biplane with a canard (forward) surface for pitch control and wing-warping for lateral control. But its longer, narrower wings, elliptical elevator, and vertical tail gave it a much more graceful, elegant appearance.
Like the 1901 glider, this one also had a spruce framework supported within pockets sewn into its muslin fabric covering. The fabric was again applied on the bias (the direction of the weave at a 45-degree angle). The wings were rigged with a slight downward droop to counteract side-slipping due to crosswinds.
Compared to their previous gliders, the Wrights' 1902 glider had a much thinner airfoil and longer and narrower wings, which their wind tunnel tests had shown to be more efficient. To improve lateral control, they added a fixed vertical rudder to the rear of the glider. They retained the reliable forward elevator for pitch control but made it elliptical in shape. |
