Propeller

or even considered. People, in this sense, are like whirligigs. They are each unique and just keep going. But that is not the only thing related to everyone. In fact the whole universe is a whirligig, the sun is the pivot and the planes are the propellers. Some whirligigs stay in one spot and never move, while some move with the wind. Some people stay in their town all the time, but some…

submarine. Just like the fishes have fins on their bodies to help them swim and dive. The planes on submarine are similar to the wings and control surfaces “(swiveling flaps)”(http://www.explainthatstuff.com/submarines.html) on an airplane. When the propellers of submarine push it forward, water rushed over the planes, cause a downward or upward force that help the submarine slowly rise or fall. When the submarine dives in the water, the fins can help move the direction they wanted by…

McGrath Wind Farm of Excellence, we visited on 22 July, 2015, the role of the facility makes electricity from wind. The facility is located in 40 kilometers south of Lethbridge, Alberta. Then, this company established it in 1962, but the facility started in 2004. The wind-generated electricity is an electricity generating system using a wind-force. The wind power energy is accepted as the maintenance of natural environments, the energy source that it can secure of the energy security as one of…

Boeing and Airbus have introduced fly-by-wire systems and lightweight, composite materials to commercial aviation. Consumer support is one of the key factors to prove that the software can make a multi propeller aircraft fly that too as simple as thumbing an iPhone. Electric cars and the computers have moved the battery technology forward to the next level. The US Department of Energy is spending millions of dollar to promote the research. This concept of…

Building my own RC polystyrene hovercraft from scratch made me realise the challenges and difficulties one might face as an engineer. For instance, producing lift was a major problem, so I made many variations of propellers to find the most effective one. To me, the most enjoyable part of the project was overcoming the obstacles. I was proud and satisfied to see it work after weeks of tests and improvements. As a fan of remote controlled cars for many years, the idea of being an engineer…

I built and crashed an airplane at the age of seventeen. To clarify, the plane was made of foam and it was controlled by a radio transmitter. However, the entire process taught me an essential lesson that I have applied to all facets of my life. My interest in flight was inspired by my father, who grew up in Jamaica and Mexico observing and envying the flying capability of birds. He also saw stunt pilots steer colorful biplanes at an airstrip in the mountains of Mexico. I was fascinated by…

During the first half of World War One, people were still trying to figure out what purpose aircrafts would serve in the war. No one had ever fought a war with aircrafts before, as wars before 1914 were fought on land or at sea. Even while most were skeptical, aircrafts quickly became involved in the war. While air combat would not change the outcome of World War One, it played an integral and essential role in drawing the war to a close. Death of pilots and those involved in aerial fighting was…

World War I started the twentieth century off with a bang. The war began when Archduke Francis Ferdinand of Austria was assassinated by Gavrilo Princip was a nineteen year-old who was a member of the Serbian terrorist group called The Black Hand. The terrorist group requested that if the country had a large population of Serbian peoples that they need to be freed. With the death of the Archduke, Austria-Hungary declared war on Serbia. Austria-Hungary also had a promise from Germany that if…

known as a nuclear bound and it lacks the cytoplasm membrane. Prokaryote structures consist of the flagella, pili, and capsules. The flagella is placed down in the plasmatic membrane and cell wall. The flagella moves by whirling its “tail” like a propeller on a boat to transport from place to place. Pili is a slick, hair like subject that is surfaced on many bacteria…

Fighter and Bomber Aircraft of WWII During World War II, aviation firmly established itself as an important part of warfare. Countries taking part in WWII quickly learned that dominating the air meant winning the war. Before WWII, most of the strategies for air warfare were mainly theoretical, since WWI had little effective air warfare, and most air to air combat at the time was primitive. Fighter aircraft are military aircraft which are designed mostly for air to air combat against other…
