...Valerie Thorburn 10/11/2014 ENG-1060 Research Paper #1 The History of the Fighter Plane You are traveling at a speed of 4000 miles an hour; your heart is in your mouth, your face ashen white, you feel as if there is a 100 pound weight on you pressing you into your seat. You are a fighter pilot and this is your first flight. There are many other pilots around you. In the world there are many pilots that fight and put their life on the line for others. They are well trained and well educated. They are to be respected for what they do. The fighter plane and pilots have come a long way since they were first seen in the air of France. The changes are mainly because of the new technology. The first aviation fighter pilots were used in World War 1.They flew very slow but stable planes. It was the Idea of a Frenchman named Roland Garros to strap a machine gun to the nose of the plane. He soon realized that there was a problem, the stream of bullets were wrecking the blade. Roland Garros then had an idea he took steel armor plates and welded them to the lower portion of the blades to deflect any bullets that might hit the blade, this idea worked but it was crude. He took his idea into combat and was able to down four planes. Before Roland Garros idea the pilots normally would use rifles and pistols to bring down a plane (3). When he was fighting later he was trapped behind enemy lines and forced down. The Germans found out his secret and...

...Airplane Flight Science Fair Project Research Have you ever wondered how an airplane flies? That happens because of four different factors. This paper explains airplane wings, lift, and stalls during flight. Since the science far experiment is what forces affect the airplane wings during a stall. Using different articles from online resources, flight, lift, and stalls were explained in numerous ways. Thrust, Drag, Weight and Lift are the four factors that allow an airplane to take flight. Dunbar (2003) explains these in depth. Thrust is a force that moves an aircraft in the direction of the motion. It is created with a propeller, jet engine, or rocket. Air is pulled in and then pushed out in an opposite direction. One example is a household fan. Drag is the force that acts opposite to the direction of motion. It tends to slow an object. Drag is caused by friction and differences in air...

...Today I dropped.” (page133) Kamkwamba’s father doesn't have money to pay tuition of Kamkwamba. Another reason is about the famine. There were droughts and floods, but in the end, most of the problems were caused by the Malawian people themselves. The decision to pay off international debt in the form of the country’s stockpile of maize, deforestation, and the election of a business-oriented president were all major reasons for the famine. Kamkwamba Likes a good engineer, he began to research and look for creative solutions. Kamkwamba’s passion for science and math led him to the local library, where he taught himself physics from textbooks. Kamkwamba even learned a new language as he went along, as the books were all in English. He was so inspired by the pictures of a windmill he saw in a book about renewable energy that he became determined to build one himself. He scavenged for spare parts at a local junkyard, ultimately coming up with materials like bicycle wheels, PVC pipe and a tractor propeller. After two months of hard work and resourceful thinking, he was able to transform these odds and ends into an electricity-generating windmill. The windmill successfully powered several lamps in his family home and later could charge cell phones as well. “Even had mobile phones on a table. You could pay to make calls, kind of like an open-air...

...What does the term of “Invisible Hand“ stand for? What are the real consequences and premises of “Invisible Hand”? Introduction In Adam Smith’s conception, it is the ‘invisible hand’ of the free market that organizes the seemingly chaotic and self-interested activities of human beings into a beneficent and industrious social order. The conception tries to describe “Self – regulating nature of market” based on natural inclination of human-being. Unplanned, unintended actions coined with natural inclination of self-interest channels ambitions towards meeting social necessities. The main motto of the argument was that the market freely will lead to perfect equality. Actually, perfect competitive market fundamentalism was bulwarked with “Invisible hand”. It is very arguable and ambiguous that why Adam Smith called this sort of regulation “invisible hand”. Cognitively, it is tangible but in terms of understanding of special mechanism is very incomprehensible and too invisible to put forward as a market regulatory factor. Self-interest as a part of human nature took a role of supervisor and established “self-regulatory nature of marketplace”. Diving into deep comprehension of the term of invisible hand, we can see that the term implies decentralization of the wealth among inhabitants. We can face with the term of “invisible hand” in his previous work called “The Theory of Moral Sentiments” which envisages the natural propensity of human-being: “They are led by an invisible hand...

...The Wright Brothers Invent the Airplane About one hundred years ago the planet earth was a much smaller place. On December 17, 1903 the Wright brothers, Wilbur and Orville, made history when they took off in flight and invented the first airplane. This is how the planet earth began shrinking geographically making it easier and quicker to travel over long distances. Wilbur was the older of the two brothers by four years. Wilbur was born in 1867 on a farm near Millville, Indiana and Orville was born in 1871 near Dayton, Indiana. As youngsters, Wilbur and Orville looked to their mother for mechanical expertise and their father for intellectual challenge. Milton, their father, brought them various souvenirs and trinkets he found during his travels for the church. One such trinket, a toy helicopter-like top, sparked the boys' interest in flying. In school, Wilbur excelled, and would have graduated from high school if his family had not moved during his senior year. A skating accident and his mother's illness and subsequent death kept him from attending college. Orville was an average student, known for his mischievous behavior. He quit school before his senior year to start a printing business. The two brothers were very intellectual and smart, but both did not ever get their high school diplomas. It just goes to show that even two of the best minds in our history didn’t have to go to college or even finish high school to become these great minds. The first time Wilbur and...

...shape and size of the aircraft. Issues related to mini aerial vehicle design are discussed in the paper. In this paper a case study of design of a 0.6 m fixed wing aerial vehicle is presented. This case study also brings out the requirement of various tools to conduct such an exercise. Introduction: Significant interest is being shown by academic institutions in research activities related to Remotely Piloted Vehicles (RPV’s) and Unmanned Aerial Vehicles (UAV’s). Flying platforms and their design with suitable payloads reinforce classroom education while exposing students to a host of flight related problems and issues of systems integration. There has been a long felt need to bring students, especially in the field of engineering, closer to the complexities and risks in dealing with actual systems. The Department of Aerospace Engineering, IIT Bombay has decided to make headway in this direction by developing remotely piloted aerial vehicles as experimental platforms[1]. The various disciplines required for such a design activity are aerodynamics, performance, structures, stability, control and propulsion. Each of these designs are different compared to conventional aircraft. Scalability cannot be applied directly and it opened up new research areas. Low speed aerodynamics, new construction methodologies, efficient power plant and Navigation Guidance and control are few emerging research fields in the development of these mini aerial vehicles. Methodology developed for the airframe...

...Writing a journal article review You may be asked to write a journal article review. Although this may be an unfamiliar exercise, it is not as complex a task as writing an essay requiring a lot of library research, and not the same as a review in The Canberra Times which is written for the general reader. Your journal article review is written for a reader (eg, your supervisor, lecturer or tutor) who is knowledgeable in the discipline and is interested not just in the coverage and content of the article being reviewed, but also in your critical assessment of the ideas and argument that are being presented by the author. Your review might therefore be guided by the following questions: Objectives | What does the article set out to do? | Theory | Is there an explicit theoretical framework? If not, are there important theoretical assumptions? | Concepts | What are the central concepts? Are they clearly defined? | Argument | What is the central argument? Are there specific hypotheses? | Method | What methods are employed to test these? | Evidence | Is evidence provided? How adequate is it? | Values | Are value positions clear or are they implicit? | Literature | How does the work fit into the wider literature? | Contribution | How well does the work advance our knowledge of the subject? | Style | How clear is the author's language/style/expression? | Conclusion | A brief overall assessment. | | | | | This image shows a close-up view of the next-generation...
