The following question, "How does an airfoil create lift?" comes from Ms. Gillespie's class. I love watching airplanes take off at the airport. I think it’s an amazing feat of human engineering that ...

We’ve probably all experimented with a very clear demonstration of the basic principles of lift: if you’re riding in a car and you put your flattened hand out the window at different angles, your hand ...

A team of evolutionary biologists and engineers have demonstrated a new structure inspired by shark skin that could improve the aerodynamic performance of planes, wind turbines, drones, and cars. The ...

The aeroacoustic analysis of high-lift airfoil systems is a critical field of research aimed at understanding and mitigating the noise generated by aircraft during takeoff and landing. High-lift ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

Here's the crux of the issue: there is a huge difference between a "spoiler" and an "airfoil" or wing. They have different shapes and do different things. An automotive airfoil is shaped like an ...

Sharks have been around since before dinosaurs roamed the earth, which has given them plenty of time to perfect the art of aerodynamics. It's no surprise then that sharks, like whales, can teach us a ...
