NASA Engineers Use Super Bowl To Decode Aerodynamics : Aerodynamics engineers including an Indian-origin scientist are studying sports balls to learn lessons in aerodynamics that will help build aircrafts more earth-friendly and allow spacecrafts to take the most efficient route to Mars in the future. Aerodynamics is the way air moves around things. The rules of aerodynamics explain how an airplane is able to fly. Anything that moves through air reacts to aerodynamics. A rocket blasting off the launch pad and a kite in the sky react to aerodynamics. Aerodynamics even acts on cars, since air flows around cars. Everything on Earth has weight. This force comes from gravity pulling down on objects.
To fly, an aircraft needs something to push it in the opposite direction from gravity. The weight of an object controls how strong the push has to be. A kite needs a lot less upward push than a jumbo jet does. By understanding how fluids flow around basic shapes such as cylinders and spheres, NASA’s engineers predict how even minor alterations in these basic shapes change flow patterns and events like Super Bowl come handy.

“Sports provide a great opportunity to introduce the next generation of researchers to our field of aerodynamics by showing them something they can relate to,” said Rabi Mehta, chief of the Experimental Aero-Physics Branch at NASA’s Ames Research Centre – located less than 16 km from the home of Super Bowl 50 – Levi’s Stadium in Santa Clara, California. What is super boul: The Super Bowl is the crowning glory of sports in the United States, but it hasn’t been without it’s mishaps. They aren’t the last minute fumbles, missed field goals, or obvious interceptions either. They’re those unfortunate outside incidents that stopped or changed the course of the game.
For us, our goal is to expose the game to the largest audience possible for the Super Bowl, What is the best way to throw a football? Why does a curve ball curve, why does it knuckle? Researchers can demonstrate the science behind these complex questions using relatively simple visualisations of fluids flowing over sports balls in small test facilities at NASA.A football is shaped like a wing and more aerodynamic than a round ball so the flow is very different.When a quarterback throws the football, he ideally wants to throw a tight spiral with high rotation rate to help stabilise the ball as it flies through the air.
“This produces lower drag than a wobbling ball so it will get there faster. Wobbling balls are also harder for the receiver to catch and more easily picked off by the defense,” Mehta added.Kicking is another aspect of football aerodynamics.“We’ve all seen how critical the final kick can be, if the ball is a little bit off you can lose the whole game and the entire season,” said Mehta.
