Structure Of The Human Powered Aircraft And The Industry Literature review

Structure Of The Human Powered Aircraft And The Industry - Literature review Example 1 – 5). Thus, a capacity for flying over the longest possible distance on limited power available from humans is a critical measure of performance for small human powered aircraft and jump type hang gliders, which must maintain a low weight while ensuring a degree of stability, safety, controllability and structural soundness. Because one of the largest weight components of an aircraft is its primary structure, the proper design of aircraft structure for human powered aircraft and hang gliders remains a challenge that decides about the success or failure of a design. The appropriate design flight conditions and the structural loads caused by a flight are variable and not immediately apparent, with flight regime and manoeuvring requirements placing additional demands on aircraft structures. Thus, for hundreds of years, if not thousands, the idea of man-powered flight has inspired many brave men to design strange contraptions with which to rival the birds (Grosser, 2004, Pp. xvi i – xix). The International Worthing Birdman Competition is an annual event held in the picturesque Worthing Town, located on England’s South Coast that encourages creativity in design and innovation for human powered / glider type flying machines (Worthing Birdman, 2011,† Worthing International Birdman Festival†). ... Because of the limitations imposed on designs of aircraft that are eligible to participate in the Worthing International Birdman Festival, no single entry to date has succeeded in gliding over the required 100 m distance. This literature review presents an examination of designs for human powered aircraft and hang gliders that will most likely present a winning entry for the Worthing International Birdman Festival. An emphasis exists for deciding about the structure of the aircraft, and the literature review should appeal to all those with an interest in human powered aircraft and gliders. Because Para gliders are gliders with no rigid form and only a simple fabric wing, with a pilot attached to the wing with high-strength cords, these designs cannot meet the specifications mentioned for the Worthing International Birdman Festival (Demand Media, 2011, â€Å"What Are Three Different Glider Designs?†). The length of the high-strength cords in a Para glider design connected to th e pilot will not permit pilots to travel far after a jump from the pier before they land in the sea. Thus, this literature review only considers hang gliders and other human powered type structures, excluding human powered helicopters (which do not have a wingspan) that are more likely to provide a pilot with the maximum height to travel before landing in the sea to present a win in the competition. It is important to note that human powered helicopters must lift the weight of the human and power engine as well as the weight of the entire aircraft structure to demand exceptionally large and lightweight rotary wings that present great complexities to render such

Environmental Ethics Essay -- shallow ecological thinking, deep ecolog

"If we each take responsibility in shifting our own behavior, we can trigger the type of change that is necessary to achieve sustainability for our race or this planet. We change our planet, our environment, our humanity every day, every year, every decade, and every millennia." -- Yehuda Berg The state of our environment has been deteriorating for centuries. Every part of the planet has been negatively impacted by man. Environmental degradation was greatly accelerated by the industrial revolution that took place in the 19th century. The industrial revolution mechanized the production of goods and introduced the use of machinery and other heavy equipment which were fueled by dirty sources of energy. At first, wood and coal powered the engines of industry, later they were replaced by natural gas and petroleum(Alters 51-63). At this point, it simply is not enough to just "do no harm" to the environment. We must immediately begin to act on behalf of the environment, instead of just not against it. My ethics concerning the environment have always run along the lines of "shallow ecological thinking,(Naess)" as Arne Naess called it. I choose to avoid pollution and to reduce, reuse, and recycle because these actions seem beneficial to humans in one way or another. This reasoning is shared by many people in regards to the environment and animal rights considering anything as a means to human ends, rather than as ends in themselves. Even the above passage from the Bible seems to allocate all the goods of the earth to humans and puts all the natural resources under their direct supervision. I understand the above passage to mean that man is obliged to look after the environment and to protect it, much like a mother looks after her chi... ...ered by a world of people. We need to keep in mind, however, that ethics do not develop spontaneously, so we must allow a bit of leeway, some room to move, grow, and evolve. With this mindset, the environmental damage can first be slowed, then stopped, and eventually reversed and mended. It may seem drastic, but this plan of action may be more necessary than the people of our needy planet realize.

A place you would love to return to again

I would love to go back to Mumbai in India, if I ever get a chance. Mumbai is one of the metropolitan cities of India. It is famous for its warm people, moderate climate, Elephanta Caves and beaches like Chawpatti, Juhu and Marine drive.It is the capital of the state of Maharashtra. Seven islands whose names are Colaba, Mahim, Parel, Mazagaon, Old Woman's Island, Wadala, and Matunga-Sion join together to form Mumbai. It is a city which is close to the Arabian Sea. It is also called Bollywood city, where most of the actors and actresses of the Hindi film industry live. I would love to return to this place because I have spent a memorable childhood in this city.Mumbai is very close to my heart. I got an opportunity to visit this place when I was studying in school. The place looked very beautiful in the eyes of a 9 yr old girl. We lived far from the city centre. There were mountains at the backdrop and when it rained, I could see the waterfalls from the window of my house.There were co conut tree all around which also added to the beauty. There was also a playing ground nearby where I played with other kids of my age. The place looked attractive to me because it was totally different from the place where we lived before we came here. In Mumbai I loved the open space it provided and of course the mountains.I have lovely childhood memories of Mumbai. I spend my school days in this city. I think this is one of the reasons that I love this place so much. I made many friends in this place. My best was a girl from Mumbai.I knew her from my school days; she studied with me in the same school. We remained friends for many years, even after I returned to Kolkata, my native place. I met girls and boys of different culture and background and had the opportunity to enjoy many parties, picnics and trips together.I still remember some activities that my family and I did in Mumbai, which was never possible in Kolkata as my father became very busy with his work. On holidays and s ummer vacations, we visited many places like the zoo, the Gate of India, Ajanta Ellora caves and Elephanta Caves.We also visited a nearby hill station called Bahabaleshwar and Goa, an exquisite place near Mumbai. I remember that most of the days after dinner we use to go for a walk. On the way there were many ice-cream stalls and my father always bought ice-creams for us. I also enjoyed different Indian festivals like Diwali, Durga Puja, Holi and Ganesh Puja.As a Bengali, we were away from home but the place felt like home to us because there were Bengali associations and our main festival, Durga Puja was celebrated in a grand way. Puja brought joy for me because I got new clothes and sweets.My mother always insisted that I and my sister participate in cultural functions. It was a good experience. I doubt that I was a good performer but I always receive loads of applauses from the audience. I grew up and because of my studies; I did not have enough time to participate in such cultur al activities anymore after we returned to our native land.  I know that Mumbai has grown a lot as a city in the past few years but I remember the place as I have seen seventeen year ago. I can still visualize my house, the playground, the mountains and the bright springs.Sometimes I fear that if I ever return to the city, I won’t be able to recognize and accept the changes that have taken place. Moreover my friends and other people whom I have known, most of them have moved elsewhere or have changed with time. However I still wish to go back and visit the place where I have spend my childhood days. It would give me immense pleasure to re-live my childhood again.Work Citation:â€Å"Mumbai Travel Guide†. 8 November 2007. http://www.mumbai.org.uk/>   

Staying in a Bad Marriage - 967 Words

There are millions of women that are being abused in their marriages. Many of these women choose to stay in these marriages, which leads to many women being murdered and families being destroyed. While there could be various reasons why women may stay in these marriages, researcher Critelli (2012) provides one main factor that explains why many women stay in those marriages. This factor is based upon different religions, leadership obligations, and the interpretations of these particular religions. Christianity is a well-known religion that often includes various denominations. Four denominations that will be discussed within this paper are Catholic, Orthodox, Lutheran, and Methodist. These denominations have a wide range of approaches in relation to roles and treatment of women in relationships and marriages. In addition, these various denominations offer insight upon the different interpretations of the role of religion in abusive marriages. To understand why many women may decide to stay in abusive marriages, we must first understand how the different denominations of Christianity perceive marriage, the views of divorce, and the process of remarriage. Catholic View of Marriage Duba (2012) explains the Catholic view of marriage as a holy covenant between the husband and wife that should symbolize the â€Å"eternal relationship between God and the church† (2012/244). Duba also discussed that the Catholic view of marriage and marital relationship is often noted within variousShow MoreRelatedDivorce Where Children Are Involved Essay1561 Words   |  7 PagesHowever, one must keep in mind that divorce is not always the answer.
