German V-2 Rocket in World War II

German V-2 Rocket in World War II In the early 1930s, the German military began to seek out new weapons that would not violate the terms of the  Treaty of Versailles. Assigned to aid in this cause, Captain Walter Dornberger, an artilleryman by trade, was ordered to investigate the feasibility of rockets. Contacting the  Verein fà ¼r Raumschiffahrt  (German Rocket Society), he soon came in contact with a young engineer named Wernher von Braun. Impressed with his work, Dornberger recruited von Braun to aid in developing liquid-fueled rockets for the military in August 1932. The eventual result would be the worlds first  guided ballistic missile, the V-2 rocket. Originally known as the A4, the V-2 featured a range of 200 miles and a maximum speed of 3,545 mph. Its 2,200 pounds of explosives and liquid propellant rocket engine allowed Hitlers army to employ it with deadly accuracy. Design and Development Commencing work with a team of 80 engineers at Kummersdorf, von Braun created the small A2 rocket in late 1934. While somewhat successful, the A2 relied on a primitive cooling system for its engine. Pressing on, von Brauns team moved to a  larger facility at Peenemunde on the Baltic coast, the same facility that developed the V-1 flying bomb, and launched the first A3 three years later. Intended to be a smaller prototype of the A4 war rocket, the A3s engine nonetheless lacked endurance, and problems quickly emerged with its control systems and aerodynamics. Accepting that the A3 was a failure, the A4 was postponed while the problems were dealt with using the smaller A5. The first major issue to be addressed was constructing an engine powerful enough to lift the A4. This became a seven-year development process that led to the invention of new fuel nozzles, a pre-chamber system for mixing oxidizer and propellant, a shorter combustion chamber, and a shorter exhaust nozzle. Next, designers were forced to create a guidance system for the rocket that would allow it to reach the proper velocity before shutting off the engines. The result of this research was the creation of an early inertial guidance system, which would allow the A4 to hit a city-sized target at a range of 200 miles. As the A4 would be traveling at supersonic speeds, the team was forced to conduct repeated tests of possible shapes. While supersonic wind tunnels were built at Peenemunde, they were not completed in time to test the A4 before being put into service, and many of the aerodynamic tests were conducted on a trial and error basis with conclusions based on informed guesswork. A final issue was developing a radio transmission system that could relay information about the rockets performance to controllers on the ground. Attacking the problem, the scientists at Peenemunde created one of the first telemetry systems to transmit data. Production and a New Name In the early days of  World War II, Hitler was not particularly enthusiastic about the rocket program, believing that the weapon was simply a more expensive artillery shell with a longer range. Eventually, Hitler did warm to the program, and on December 22, 1942, authorized the A4 to be produced as a weapon. Though production was approved, thousands of changes were made to the final design before the first missiles were completed in early 1944. Initially, production of the A4, now re-designated the V-2, was slated for Peenemunde, Friedrichshafen, and Wiener Neustadt, as well as several smaller sites. This was changed in late 1943 after Allied bombing raids against Peenemunde and other V-2 sites erroneously led the Germans to believe their production plans had been compromised. As a result, production shifted to underground facilities at Nordhausen (Mittelwerk) and Ebensee. The only plant to be fully operational by wars end, the Nordhausen factory utilized slave labor from the nearby Mittelbau-Dora concentration camps. It is believed that around 20,000 prisoners died while working at the Nordhausen plant, a number that far exceeded the number of casualties inflicted by the weapon in combat. During the war, over 5,700 V-2s were built at various facilities. Operational History Originally, plans called for the V-2 to be launched from massive blockhouses located at Éperlecques and La Coupole near the English Channel. This static approach was soon scrapped in favor of mobile launchers. Traveling in convoys of 30 trucks, the V-2 team would arrive at the staging area where the warhead was installed and then tow it to the launch site on a trailer known as a Meillerwagen. There, the missile was placed on the launch platform, where it was armed, fueled, and the gyros set. This set-up took approximately 90 minutes, and the launch team could clear an area in 30 minutes after launch. Thanks to this highly successful mobile system, up to 100 missiles a day could be launched by German V-2 forces. Also, due to their ability to stay on the move, V-2 convoys were rarely caught by Allied aircraft. The first V-2 attacks were launched against Paris and London on September 8, 1944. Over the next eight months, a total of 3,172 V-2 were launched at Allied cities, including London, Paris, Antwerp, Lille, Norwich, and Liege. Due to the missiles ballistic trajectory and extreme speed, which exceeded three times the speed of sound during descent, there was no existing and effective method for intercepting them. To combat the threat, several experiments using radio jamming (the British erroneously thought the rockets were radio-controlled) and anti-aircraft guns were conducted. These ultimately proved fruitless. V-2 attacks against English and French targets only decreased when Allied troops were able to push back Germans forces and place these cities out of range. The last V-2-related casualties in Britain occurred on March 27, 1945. Accurately placed V-2s could cause extensive damage and over 2,500 were killed and nearly 6,000 wounded by the missile. Despite these casualties, the rockets lack of a proximity fuse reduced losses as it frequently buried itself in the target area before detonating, which limited the effectiveness of the blast. Unrealized plans for the weapon included the development of a submarine-based variant as well as the construction of the rocket by the Japanese. Postwar Highly interested in the weapon, both American and Soviet forces scrambled to capture existing V-2 rockets and parts at the end of the war. In the conflicts final days, 126 scientists who had worked on the rocket, including von Braun and Dornberger, surrendered to American troops and assisted in further testing the missile before coming to the United States. While American V-2s were tested at the White Sands Missile Range in New Mexico, Soviet V-2s were taken to Kapustin Yar, a  Russian rocket launch and development site two hours east of Volgograd. In 1947, an experiment called Operation Sandy was conducted by the US Navy, which saw the successful launch of a V-2 from the deck of the  USS Midway (CV-41). Working to develop more advanced rockets, von Brauns team at White Sands used variants of the V-2 up until 1952. The worlds first successful large, liquid-fueled rocket, the V-2 broke new ground and was the basis for the rockets later used in the American and Soviet space progra ms.

Can laws influence incidence of chronic illness Essay

Can laws influence incidence of chronic illness - Essay Example Enacting laws is one of the methods that can help stop the prevalence of obesity and chronic diseases. This paper will look at the how enacting laws can help reduce the prevalence of chronic diseases and whether enacting such laws is ethical. A recent research suggests that cigarette smoking is the leading cause of preventable deaths (Meetoo, 2010). However, this is despite the various public awareness efforts and the laws that have been enacted over the years to stop this. Obesity and chronic diseases are likely to be the leading causes of preventable death in the future if proper measures are not taken to address this menace (Meetoo, 2010). The United States of America government over the years has enacted strict laws to help reduce cigarette smoking. The tobacco control act is one of such legislations whose main aims include; making tobacco products more expensive, preventing people from starting using tobacco and helping those already using tobacco products to stop. These laws have had a small effect on controlling the use of tobacco products. However, this effect cannot go unnoticed, as it has helped save many people’s lives. The government should embark on enacting laws to help reduce the prevalence of obesity and chronic diseases. In addition to raising public awareness on the issue, laws will go a long way in reducing the prevalence of chronic diseases and ensure it does not become the leading cause of preventable death. The laws should mainly target at the marketing strategies used by fast food outlets, branding and labeling of fast foods. The sale of soft drinks and fast food products around and in schools should also be prohibited. The government should also make sure that nutritious foods are subsidized to make sure they are affordable regardless of one’s economic status (Meetoo, 2010). Is it ethical to enact laws that are aimed at

Personal Narrative- The Real Me :: Personal Perspective Essays

Personal Narrative- The Real Me I was sitting, waiting impatiently for Adam. All of a sudden, this red Toyota Tacoma flew into my driveway, screech. â€Å"Hey sweetie! Are you ready to go and eat?† he screamed out of his fire red truck. In the mean time, I was sitting there, glaring out the window, talking to myself like a harebrained would do, asking the stupidest questions, â€Å"Is he going to like my disturbed family? What is he going to think of my annoying redneck relatives? I hope he likes fish. Am I too dressed up for dinner?† W arrived at my grandmothers’ house around 5:30, at once my aunt Gaye grabs me by the arms, â€Å"Hey girl! Give your favorite Aunt Gaye a hug!† pulling me under her arm. I yanked my head away, but I already got disillusioned by the smell of month old gym clothes. â€Å"And who is this fine young boy behind you?† I was so red by this point that I just took him to the kitchen, introduced him to the rest of my family, that was there. While introducing Adam to Casey and Ben, Gracie, my three year old cousin, ran into me, knocked me off my feet, while giving me the biggest bear hug ever. She rapidly ran away just after noticing Adam; she is very shy. Adam and I began to laugh as Gracie ran into the wall. Lacey, my five year old cousin also Gracie’s big sister, runs straight up to Adam and gives him a hug; she is very sweet. Finally, after Adam met everyone but my parents, they showed up. â€Å"Hey mom and dad, this is Adam. He has met the rest of the family and it smells like dinner is ready. Shall we eat?† I rushed along so there wouldn’t be any embarrassment. On the table, my grandmother arranged the food, placing each dish in its assigned place. The table was crawling with fried food: a huge pan of 100 crispy, crunchy fish, squishy hush puppies, and black tatter-tots, a bowl of bright green, grassy coleslaw, with a cottage cheese texture. Gross! Piling food onto ours plates, Adam and I rushed outside to sit in front of the television in hopes for the game to be on. While eating I noticed that Adam was throwing away the fish tails, â€Å"Adam! What are you doing? You are supposed to eat the fish tail! Here let me show you.

Similarities And Differences Of Buddha And Christ

Religion is somewhat important to a lot of people around the world. It helps us guide in our everyday life. To follow the beliefs and traditions brings faith to whatever religion we are into. In our era today, we come up with a lot of religions and two of the major religions are Buddhism and Christianity. Buddha specifically said not to believe to the things that is passed on and that we’re just written down etc. on face value. He did not urge us to put faith just in texts, or enough faith in their value to trawl through them-quite the opposite.What we’ve known is that, all Buddhist school agrees that one’s salvations from suffering are in one’s own hands. Siddharta Gautama was born into a royal family in the sixth century B. C. His experiences when he was a young adult with the outside world sent him to look out a greater understanding of life and spiritual understanding. Siddhartha achieved the powerful enlightenment through seeking guidance. He was know n as the Buddha from that point which means â€Å"the Enlightened One†.From then on and for the rest of his life, Buddha traveled from great distances to teach people about the one path of salvation. His pupils continued to extend his teachings after Buddha’s death. Hinduism, the most widespread religion in India, had become tightly controlled when Buddhism developed. And today, Buddha’s teachings still followed by a lot of people throughout the world. â€Å"Christ† as the identification, Jesus is not accepted within Judaism.Christians are called â€Å"Nazarenes† in Talmudic Hebrew because in the New Testament, Jesus is described in as being from the city of Nazareth. Being a â€Å"Christian,† one has to follow the teachings of Jesus Christ, some believe that an individual must attend a mass and go to church and participate in baptism. Death and resurrection of Jesus Christ is necessary to others, instead of a belief and acceptance in their life. â€Å"Nicene Creed† is the ancient text, which some theologians consider a Christian who accepts this.This is accepted by the Orthodox, Anglicans, Catholics, Lutherans and the rest of the mainline Protestant Churches. In spite of important differences of interpretation and opinion, Christians share a set of beliefs that they hold as essential to their faith. The resurrection of Jesus Christ is considered and said to be the cornerstone of their faith among all Christians and the most important event in human history. Within the body of Christian beliefs, the death and resurrection of Jesus are the two most core events on which much of Christian doctrine and theology depend.Christians commemorated these essential doctrines of the Christian faith during Good Friday and Easter Sunday, particularly during liturgical time of Holy Week. One wrote, â€Å"If Christ was not raised, then all our preaching is useless, and your trust in god is useless. † Christians believe th at one can be saved from sin and have eternal death through faith in Jesus. The Gospel of John said that He â€Å"takes away the sins of the world†. One’s reception of salvation is related to justification. Generally, Christian churches accept and teach the New Testament account of the resurrection of Jesus.A lot of people believe that Christ may have been inspired by Buddhism, and that the texts of the Nag Hammadi and Gospel of Thomas influence this. Apparently, It has also been asserted that the story of the birth of the Buddha was well known in the West, and it was influenced the story of the birth of Jesus. The two major religions which are Buddhism and Christianity are compared and emphasized their differences by a lot of scholars, perceived similarities in the teachings in the spiritual intent and practices.It is said to be that it may be the result of a direct or indirect influence of Buddhism on early Christianity, or arising from separate but similar developme nts, or remain divided whether the religious parallels are coincidental. Jesus is not mentioned in any Buddhist text and so, Buddhist views of Jesus differ. â€Å"That there are startling coincidences between Buddhism and Christianity that cannot be denied, and it must likewise be admitted that Buddhism existed at least 400 years before Christianity.I go even further, and should extremely grateful if anybody would point out to me those historical channels through which Buddhism had influenced early Christianity. † Buddha the new born prince is adored and predicted by seer Asita and is celebrated his birth. Jesus the new born prince is adored and predicted by seers â€Å"from the east† who celebrated his birth. Buddhist Trinity (Tiratna) and Baptism: â€Å"I take refuge, Lord, in the Buddha, the Dhamma, and the Sangha. † â€Å"Enough, I say, with this external bath. I am satisfied with this internal bath: confidence in the Blessed One. â€Å"Jesus Trinity and B aptism is written as follows: â€Å"baptizing them in the name of the Father, and of the Son, and of the Holy Spirit†. Lastly, if there are any similarities and differences on people, the faith and respect to each other’s religions is still one of the most important things that should always be present to anyone whether in a Catholic teaching, in Buddhism, or any form of religion.

Globalization Of The Marketplace Has Brought About Costs...

Regionalism Briefing Introduction The globalization of the marketplace has brought about costs and benefits for all countries and industries. A main benefit of globalization for producers, like the those of us in the manufacturing industry is access to more customers however, competition also increases which decreases the potential for sales. Economic integrations are a part of global business that look to increase the efficiency of resources. Economic integrations and trading blocs are instituted in order to remove barriers to trade. The idea is that by removing barriers each individual economy will be able to utilize their own resources and those of others with more with more efficiency (Hill, 2013, p. 256). The result is that a common†¦show more content†¦Free Trade Area A free trade area is the lest integrated form of economic integration - â€Å"all barriers to the trade of goods and services are removed† but members still has the ability to set their own rules when trading outside of the bloc ( Hill, 2013, p. 257). The North American Free Trade Agreement (NAFTA) is the most recognizable free trade area (Hill, 2013, p.257-258). The major argument against free trade areas is that jobs which can be done for less are moved to other countries (Ho, 2016). In order to provide the congressional committee with an overview of the impact free trade areas have had on the US manufacturing industry this text will focus on NAFTA’s impact. NAFTA NAFTA is a free trade agreement between the US, Mexico and Canada that was implemented in 1994 (Childress, 2012, p. 23). Barriers to trade were removed in order to encourage trade between the countries (Childress, 2012, p.23). This allowed each country to focus on producing goods and services that their own local factors of production allow them to do most efficiently and trade for those which can be produced for less and of higher quality in other countries. â€Å"The U.S. lost roughly 800,000 jobs to Mexico between 1997 and 2013† NAFTA wa â€Å"the key driver for job losses† (Lunby,2016). Many US manufacturing companies moved production to Mexico where labor is cheaper as labor is the highest direct cost associated with manufacturing,
