Flow field of a butterfly mimicking flapping model with plan form of various shapes and butterfly-shaped wings is studied. The nature of the unsteady flow and embedded vortical structures are obtained at chord cross-sectional plane of the scaled wings to understand the ...
referred to a vertical bend or extension of an airplane's wing. This vertical part of the wing converts otherwise wasted vortex energy into thrust. This small change to a plane's wing saved the industry when aviation was suffering the hit of high fuel process during the 1973 fuel crisis. ...
There is a weight to all on Earth. Gravity pulls things down, which causes this force. A plane must be propelled in the opposite direction of gravity in order to travel. The force needed to push an object is determined by its weight. In comparison to a jumbo plane, a kite needs much ...

The first plane and glider designs had a lot of bird-like characteristics. Wind tunnels proved that many of those ideas were rather bird-brained. Stringer/Hulton Archive/Getty Images In hopes of taking humans to the heavens, early flight engineers tried to follow the example of birds. Leona...

Ahmed body is made up of round front part, a moveable z slant plane in the rear of the body to study the detachment phenomena at different angles, and a rectangular box which link the front part and the rear slant plane. The principal objective to study such a simplified car body is ...

The lift conditions created by the interaction of a plane's wing and surrounding air are vital. Drag and thrust — or resistance and forward motion — entail the other main concepts of airplane aerodynamics. Aerodynamics in general concerns how certain forces affect the way objects move through...
