One of the challenges of experimental fluid dynamics is capturing information about a flow that varies in three spatial dimensions and time. Experimentalists have developed many techniques over the...

Akademie letectví :: číslo 12 / 2009 / Airfoil characteristics - Charakteristiky profilů
An airfoil is a surface designed to obtain lift from the air through which it moves. Thus, it can be stated that any part of the aircraft that converts air resistance into lift is an airfoil. The profile of a conventional wing is an excellent example of an airfoil. Notice that the top surface of the wing profile has greater curvature than the lower surface. The difference in curvature of the upper and lower surfaces of the wing builds up the lift force. Air flowing over the top surface of…
philippe starck micro wind turbines
the blades of the micro wind turbines are made of transparent plastic, which is great, as it will be virtually invisible up on the roof.
