Teen’s Research Suggests Rotating Wing Parts Might Improve Aircraft Safety

Devices that exploit the identical aerodynamic effect that makes a maneuver deflect might one day improve aircraft safety. How? Such a device could avoid some aircraft stalls and spins. Such imbalance control one in every 10 small-plane accidents in the United States, notes Rylan Gardner.
The 14-year-old lives in Mesa, Ariz., where he attends 9th grade at Franklin Junior High School. He arranged such a device as a science fair project.
Air speeds up as it flows over the upper surface of an aircraft’s wing. That faster flow lowers the air pressure. It’s that pressure difference between the upper and lower surfaces of a wing that generates the lift that keeps an aircraft aloft.
But there’s different way to create lift, he notes. This different is known as the Magnus effect. It develops when air flows past a rotating sphere or cylinder, Rylan explains.
The air slows down On the side of the orb or cylinder that’s rotating into the wind, here, air pressure escalates. On the side where the area revolves away from the wind, air speeds up. There, air pressure drops. The difference in pressure between the two sides creates a push against the cylinder or sphere. This generates lift.
Rylan explored this idea in a science fair project last year. That examine accomplished the teen to contest in the ninth annual Broadcom MASTERS competition.
Math, Applied Science, Technology and Engineering for Rising Stars (MASTERS) .This set up for middle-school researchers was built by Society for Science & the Public (which publishes Science News for Students). The Broadcom Foundation headquartered in Irvine, Calif., bankroll the event, which brings together 30 finalists each year to undertake team challenges.
Aircraft stalls and spins account for not quite one in every eight fatal accidents in small planes, the teen notes. Even experienced pilots can have trouble recovering from such stalls and spins. But replacing the leading edge of an aircraft’s wing with a rotating cylinder might help, he says.
