THE GURNEY FLAP
ABSTRACT
A Gurney Flap is the simplest trailing edge device which can be used as a high lift device for low speed applications like micro air vehicles, gliders, wind turbines etc. The Gurney Flap is named after American aero dynamist Dan Gurney who introduced it in the form of a vertical tab attached to the trailing edge of an ordinary aerofoil. This modification makes the flap capable of producing higher lift force at lower velocities.
This paper is based on the experimental analysi ....etc

The History and State of the Art of
Variable-Speed wind Turbine
Technology

ABSTRACT
Early wind turbines used for performing mechanical work (pumping, grinding and cutting) optimized aerodynamics by being allowed to run at variable speed. Some of the earliest DC electric wind turbines were allowed to run at variable speed. With the advent of gridconnected AC turbines, rotational speeds were limited in order to control the wind turbine AC frequency output to equal the grid frequency. With the advent of se ....etc

Wind tunnel is a device used to test aero models, automobiles and building structures. It is used to give appropriate shape to the structure. We calculated aerodynamic characteristics analytically for different models whereas wind tunnel can give practical values and we wanted to know how this can be designed ....etc

What is an air craft?

All man made contrivances which fly, that is to say which are kept in the air by forces produced by the air are called aircraft.

Eg: balloons, kites, aeroplanes etc.

There are two kinds of air crafts, those which are lighter than air and those which heavier than air. The lighter than means their weight by volume is less than that of air. Heavier than means the weight by volume is heavier than that of air. The former includes balloons, airships etc. and the later comprises kites and aero planes.A heavier than air ....etc
