Airfoils work because the higher speed of air going over the top surface results in lower air pressure than the slower air beneath. If you drilled a hole top to bottom in an airfoil, which direction ...

Natural laminar flow is a known means of reducing aircraft drag and energy consumption, but its practical implementation is difficult on commercial airliners that cruise at transonic speeds and ...

Natural laminar flow (NLF) airfoils are key to achieving optimum performance and fuel efficiency in many vintage and current production turbine-powered business aircraft. NLF is not a new discovery.

A novel FlowViT-Diff framework that integrates a Vision Transformer (ViT) with an enhanced denoising diffusion probabilistic model (DDPM) for super-resolution reconstruction of high-resolution flow ...

A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

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 ...
