We often think of air as something light and weightless. But in reality, the air that surrounds us is exerting a huge amount of force on us. The faster you go, the harder the air pushes on you, and more is the energy required to move forward. Now imagine how large the impact of this force would be on fast-moving objects such as airplanes, rockets, or F1 race cars. Without the understanding of how air behaves when things move through it or how air moves around things, we'd never be able to design planes, spacecraft, wind turbines, skyscrapers, bridges, or even golf balls. Aerodynamics is one of the most important areas of study because it provides the basis for all these technologies. It can have a huge effect on fuel consumption and the performance of automobiles. So, engineers go to great lengths to manipulate air flow in order to minimize the energy requirement and achieve high performance. How do they achieve this? What can paper planes teach us about the science of aerodynamics? Can airplanes with cylindrical wings fly? What is the similarity between a plane and an F1 car? Will flying cars ever move out of the pages of science fiction? What lessons do owls and hummingbirds have to give about the art of flight? Explore this module to find out.
