commercial aircraft industry‚ fuel efficiency plays a major role in the current scenario wherein fuel resources are depleting rapidly. Induced drag is an important phenomenon in determining the fuel efficiency of an aircraft. The less induced drag is‚ the more fuel efficient the aircraft is. Winglet-an extension at the wing tip‚ also called as wingtip devices is one of the proven methods of reducing induced drag at wingtips. Winglets effectively

Enjoy Learn and align with Curriculum September 2008 Paper Wings Guidelines This may look ridiculous and appear to be a child’s play. As you use the kit and build your first plane‚ you will realize that it is not all that simple. Soon you will learn to make the plane to fly and discover the joy of flying. In the process you will learn the nuances of flying intuitively. This

Mainly‚ the aircraft are divided into two main control surfaces which are the primary flight control and the secondary flight control. The primary flight control is a basic control surfaces used to maneuver such as rolling‚ pitching and yawing. Meanwhile‚ secondary
