Why the F-14’s Wings Moved by Themselves



The F-14’s wings weren’t fixed; they moved by themselves in flight. Most people think planes have fixed wings that can’t change in flight. Look closer at the glove, where a steel pin holds each wing like a hinge. Now watch it swing: spread to 20 degrees for slow flight and carrier landings, and it grabs extra lift. But near the speed of sound, a spread wing builds huge drag. So at supersonic speed they sweep back to 68 degrees, and the drag falls off. The Central Air Data Computer set the sweep from Mach number.
