to generate electricity. This process is achieved by creating a propeller and connecting it to a motor. This motor lies on a free rotating base that rotates above a stand (truss) that supports the whole mill. Rotating the base to face the direction of the wind is achieved by connecting a back rudder to the base. • How does it work? Electric energy generation starts when the wind rotates the propeller blades – that have a specific angle of attack- ‚ thus rotating the

“The Evolution of Airplanes” Introduction This year is the 200th birthday of Charles Darwin (1809-1882)‚ the father of evolution. Darwin’s evolution theory proposes that all species of organisms‚ including human beings‚ evolved from common ancestors. There are five main characteristics in his evolution theory. First‚ there are variations among each population. Second‚ organisms compete for limited resources to exist. Third‚ traits of offspring are inherited from their parents. Forth‚ organisms

The first part is to develop a variable pitch propeller. Then second and the main aim of this project is to design a control mechanism by which the propellers would rotate at a constant speed‚ at varying wind speeds by adjusting their pitch. This would be achieved by using wind sensors (anemometer) and a microcontroller. The sensors would measure the wind speed and feed that to microcontroller which would in turn calculate the pitch of the propellers to keep them rotating at constant speed. (Optional)

Underwater Treasures: Titanic A major shift in our innovative world occurred during the beginning of the 20th century. Inventions that rule our era today were first brought upon in the early 1900s. One of the most notorious of these inventions was the steamboat. During this time there was a big transition from sailboat to steamboat. A significant change as to how naval vessels were built and operated took place‚ which sometimes resulted in conducting problems leading to tragedies. One of the most

Appold in 1851. Then in 1902 Renault patented the centrifugal supercharger. This marks the application of turbo-machinery to engines. In 1908 Lorin proposed the forerunner of the motorjet (we will see this shortly)‚ where air flow from behind the propeller was directed to a combustion chamber to produce jet thrust at the rear of an aircraft. Next in 1917 Morize (in France) proposes and Harris (in England) patents the motorjet. In a motorjet a conventional engine is used to drive a compressor which

This idea is good for a display project‚ an engineering project and an experimental (investigatory) project. The main structure is made of Styrofoam board that is available at hardware stores and home improvement stores. Materials used in this project are: Simple Switch‚ Electric Motor‚ Battery Holder‚ Propeller‚ wire‚ Styrofoam cup‚ Popsicle stick Procedure:

Abstract - This paper is a presentation of the design methodology and realization of the Quad-Copter‚ a model aircraft based on a four-propeller design. The Quad-Copter can be controlled by radio transmission or operate under the guidance of limited autonomous protocols. Flight stability of the Quad-Copter is achieved using a five degrees of freedom (DoF) inertial measurement unit

If you want to program a PIC you’ll have a hex file created by your assembler or created by someone else(see my propeller clock). You will also need to drive the programmer with some software.
