The Science of Launching an Airplane by Catapult

Science Fair Project Idea

Scientific Method

Naval fighter pilots seem to defy physics each time they fly their jets off of an aircraft carrier. Normal runways are thousands of feet long so that airplanes can develop enough lift to fly. But a runway on an aircraft is much shorter. How can naval pilots get their fighter jets into the air without falling off the carrier into the ocean? Well, because they get a boost from a catapult! Sounds unbelievable? It's not, and you can find out more about catapult-assisted takeoff in this aerodynamics… Read more
