The Failure of the De Havilland Comet Aircraft
Following World War II and the jet engine technology that emerged largely toward its end, aerospace engineers knew well that the technology had great potential for use in the commercial aviation industry. The Comet was the first aircraft to utilize jet propulsion; however, its designers failed to consider the metallurgy of the aircraft’s materials under flight conditions or the consequences of their atypical window design. The aircraft was designed by Britain’s De Havilland Aircraft Company and entered service in May 1952. After a year of service, however, the design issues mentioned above resulted in the failure of several Comet aircraft. Extensive evaluations revealed that repeated pressurization

The aircraft represented the first attempt to incorporate a relatively new technology in to a highly complex mechanical device. That task itself posed many problems which De Havilland engineers made great progress at solving, such as developing a system to keep the aircraft cabin at a stable pressure, integrating hydraulic controls, and constructing the fuselage so that it did not weigh too much but remained strong. Why exactly the design errors were not caught was primarily due to oversight. In several cases, notably the windows and the aluminum alloy, De Havilland engineers based their decisions on misleading data. They believed that, despite the Comet’s unusual design aspects, it erred very reasonably on the side of safety. Pressure from the British government to beat other companies and countries to the jetliner era certainly would have made De Havilland test as thoroughly as it could as quickly as it could, and in their haste the engineers did not detect damage which emerged quite gradually. The decision to test the aircraft under static conditions alone could well have been the result of data that suggested the fuselage was much stronger than it really was. Despite that, Comets did fly for about a year without any major incidents, and this fact serves as a testament to De Havilland’s bold and productive venture into revolutionary commercial aircraft
In 1940, Preston Tucker created the Tucker Aviation Corporation, and wanted to manufacture aircraft and marine engines. He designed a fighter aircraft, the Tucker XP-57, which the U.S.A.A.C. took an interest in. Again, this n...
Was the "Hindenburg disaster" a result of sabotage committed by the opponents of the Nazi organization? Did a bolt of lightning strike the zeppelin? Or was one of the most devastating accidents in aviation history nothing but a cunningly planned insurance fraud?
Is there a possibility that violence and fraud both have a lot in common? Is Dante’s reverence of the classical scholars more vivid in this canto despite his brevity? Does Virgil’s explanation of why usury was a sin convincing? Why did Dante raise the question on usury at this point since there seems to be no relevant connection to the other two main vices? These are the kinds of questions that make this canto very interesting. Canto XI offers us something different from all the action of the past by providing a map of what lies ahead; and what moral concepts would come to surface. In other words, Virgil gives Dante a quick overview of Hell’s structure.
...lity for what it is but also gives me motivation to either make the world a better place. Through his writings he gives us a choice that I feel is vital and has the abilities to distinguishes his readers from good and evil, the just and unjust. This is a form of writing in relation to all societies that I have never seen before and I feel that it is vital for all to read Gulliver's Travels so that they can look within themselves and see who they are as individuals. Overall, it is my opinion that Jonathan Swifts works on Gulliver's Travels exemplifies a true literary masterpiece. It gives us a true description of society and how we as individuals interact with on another. It tells us of our "corrupt lawyers, politicians, avaricious doctors, mass slaughters in wars over trivial pretexts-aspects of our experience as well as of Gulliver's and reminders that this narrative Gulliver's and his experiences implicates the reader in the moral problem of how to judge-and perhaps how to change-society. In all there is a lot to learn from these writing and tell us a lot about society and how we as individuals need to gain a better understanding our ourselves as well as society as a whole.
Travelling at a speed twice that of sound might seem to be something futuristic; however, this feat has already been achieved almost 40 years ago by the world’s only supersonic passenger aircraft-The Concorde. Concorde brought a revolution in the aviation industry by operating transatlantic flights in less than four hours. The slick and elegant aircraft with one of the most sophisticated engineering was one of the most coveted aircrafts of its time. However, this was all destined to end when Air France Flight 4590 was involved in a tragic disaster just outside the city of Paris on July 25, 2000. The crash killed 113 people, but more disastrous was its impact. The belief and confidence people had with Concorde gradually started to fade, and finally Concorde was grounded after two and a half years of the crash. Official reports state that the main cause of the crash was a piece of metal dropped by a Continental aircraft that flew moments before Concorde, but, over the last decade, the report has met a lot of criticism, and many alternative hypotheses have thus been proposed.

Past the political satire and laughable motifs in the book Gulliver's Travels by Jonathan Swift, the purpose of this story is to show everything ignoble and tactless of the human species in general and that humans are truly disgusting. Also exploring the idea of a utopia. Swift uses the literary device of political satire to show how childish and ignorant human acts were. This is because during Swift's time in the eighteenth century, Britain was modernizing at this time. The reader follows the four narrative travels of the main character, Lemuel Gulliver. Each of the four voyages Gulliver has traveled to, is a different society that portrays one of the main ideals of the eighteenth century in Britain. The four places Gulliver has traveled to were Lilliput; being Gulliver's first voyage, Brobdingnag; his second voyage, Laputa; the third voyage, and lastly to the land of the Houyhnhms; being his last voyage and afterwards traveling back home to England. The experience from being exposed to these four societies has had a huge impact on how Gulliver now sees humans.
Swift successfully is able to criticize England flaws through Gulliver’s Travels without making it apparent to England. Gulliver is used as a puppet or a secret way to show the Flaws of England. Gulliver is a character who starts out by loving England and cannot stop talking about it once he is able to communicate to the societies. The flaws pointed out still are issues of this time. The issues with the society’s pertain almost anytime and anyplace showing they are still issues that need to be
In Gulliver’s Travels, Swift uses multiple examples of political, religious, intellectual, economic, and social satire to exhibit the faults of Europe during the eighteenth century. This story, however, also has contemporary connections. The high and low heels of Lilliput, for example, can represent Democrats and Republicans in the United States. Swift’s use of satire allowed him to criticize what was happening in Europe at the time without being too obvious about it. Whereas many other novels were being burned for criticizing governments, Swift was able to mask his criticisms through satire. He was still able to inform the readers of the faults of Europe without angering any leaders. Ultimately, Swift is able to use satire to comment to serious societal issues of the eighteenth century while still providing an entertaining novel.
Jonathan Swift's story, Gulliver's Travels, is a very clever story. It recounts the fictitious journey of a fictitious man named Lemuel Gulliver, and his travels to the fantasy lands of Lilliput, Brobdinag, Laputa, and Houyhnhmn land. When one first reads his accounts in each of these lands, one may believe that they are reading humorous accounts of fairy-tale-like lands that are intended to amuse children. When one reads this story in the light of it being a satire, the stories are still humorous, but one realizes that Swift was making a public statement about the affairs of England and of the human race as a whole.
An endeavor, such as the one taken by Gulliver always comes with a risk. Considering the fact that he was not content with his human nature, and demonstrated his preference for animals and their set of organization. One may ask why Gulliver preferred the lifestyle of horses to that of men. Answering this question, gives us a lead to track the madness that evolved as he went along this journey. Gulliver was unsatisfied with the state of affairs in his own country and was looking for a country which is Utopian with what he had. His anger was first against the authority of the land, the Kings and Queens, the religious set up and how these authorities proclaim laws and procedures that don’t favor the masses. To some extent it can be said that Jonathan Swift who chose this satirical method of writing was an agent of change for the ordinary people.

The jet engine is a great mechanical piece of engineering. It has been used in almost all aircraft since its invention. This one improvement in aircraft allowed aircraft to fly higher, faster, and more efficient. The turbocharged engine invented by GE was the main building block for other engines. Since its invention, the jet engine has been the workhorse for all jet powered aircraft.
Many people contemplate telling the truth due to the consequences, but Johnathan Swift has found an original idea and expressed it by writing Gulliver 's Travels. It was a story based on satire and was meant to ridicule the way his country operated. Each part was an original installment meant to criticize the way his country operated in the form of education, politics, science, etc. Swift shamed his government and the politicians involved in the process of running the country, which they did in the most beneficial way for themselves rather than their own people. He uses the conflicts in the countries he visited to discuss the number of problems with England. This book was meant to educate the people of all of the dishonesty their leaders have shown and will continue to show unless there is an intervention. Swift 's comments on the British society are accurate and most definitely helped lift the ignorance of the world to this day.
There are many inventions of the future that people either know or hope will happen and some inventions that people have never thought that would happen in this or the next lifetime. For instance, one piece of future technology that I believe may come to pass is the invention of flying cars. Since the time of being young and watching the Jetsons, many people have been waiting to see the first flying car. While bringing up the idea of a flying car to a lot of people would seem absurd or downright impossible to some, I actually believe that it is very much so possible to create given how far technology has come in the past few decades. I think that it is a very logical conclusion to assume that at some point in the future engineers, car makers, and others will start to pursue other alternatives to avoiding traffic jams and other problems on the road, and instead begin to examine the possibilities of taking to the air as an alternative solution. There is much talk about it over the internet and many people would like to try flying cars. While it would greatly improve traffic for those that prefer staying on the ground, it may prove dangerous in the beginning because of accidents in the air with other cars, planes, trees, and buildings. Some would say though, that the convenience would outweigh the risks because there would not be traffic jams, or detours because of road work. These cars would need something like a GPS system and an anti-wrecking system so people would not run into each other or other objects (How Flying Cars Will Work).
