Passenger To Freighter Conversion Of Aircrafts Engineering Essay

Passenger To Freighter Conversion Of Aircrafts Engineering Essay The purpose of the report is to provide detailed description for future aerospace engineers on how and why a P2F (also known as PTF or Passenger-to-Freighter) conversion is carried out. 1.2. Background Ever since the new millennium started, P2F conversions on aircrafts have become more common in the civil aviation industry. Major civil aviation industry companies (Airbus, Boeing, etc.) started researching with designs on how to modify an airframe structure of their ageing passenger jets to cargo freighters. In conjunction with the current economic situation, civil aviation logistic companies are trying to find ways to cut down expenses on replacing older cargo freighter aircrafts- buying P2F converted aircrafts. Furthermore, P2F conversions extend lifespan of passenger jets, providing first-hand quality P2F cargo aircrafts at second-hand cargo freighter prices. Since there is an increase in demand in the cargo freighter industry more companies will look at P2F conversions .Mainly because it is more economical for the company and they can gain the same amount of revenue at the same time. 1.3. Methodology The information was gathered from a few websites through the internet, books and magazine references .The content was retrieved from websites like http://www.eads.com , books like, magazines like. 1.4. Scope The Focused areas are mainly about the structural differences between a freighter aircraft and a passenger aircraft. In addition, the report will include structure of freighter planes. In addition, it will include the pros and cons of P2F and how the conversion is carried out. Lastly, this report includes the technical effects to the aircraft structure. 2. P2F Conversion Procedures There are various types of P2F conversion procedures. The various procedures are basically created by primary manufacturers (Boeing and Airbus) and assorted conversion companies (EADS (European Aeronautic Defence and Space Company) and SIAEC (Singapore International Airlines Engineering Company)).As a result , there are many different procedures for a P2F conversion to be complete. The following procedures will be according to the 4-month conversion of the Airbus A310 wide-bodied airliner into the Airbus A310-200F by Elbe Flugzeugwerke (EFW).In the following few paragraphs I will discuss about the different procedures carried out during a P2F conversion procedure. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 2.1. Preparation before conversion The airplanes paintwork is scraped off. Thereafter, a fraction of the passenger cabin is taken out. The aircraft is then jacked into a neutral stress point for 4 weeks for the modification of the airframe. With the plane partially empty it is jacked up into a neutral stress point for 4 weeks for the adjustment of the aeroplanes body. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 2.2. Plug windows Now that the aircraft does not carry any more passengers, windows in the aircraft are useless. The windows previously used for passengers to look out of the aircraft are now plugged (covered up). As u can see in the image below, there are no more windows in a freighter aircraft because it saves time on maintenance and for safety reasons. Therefore the windows are plugged.(Marcel van Leeuwen, 2006, Boeing 747 Large Cargo Freighter Arrives in Seattle [online]. Civilian aviation news. Available from: http://www.aviationnews.eu/2006/09/17/boeing- 747-large-cargo-freighter-arrives-in-seattle/) Figure 2.6: Plugging of Windows (Airbus Freighter Conversion, 2010) 2.3. Removal of unwanted material Anything in the aircraft that is not needed anymore is removed from the aircraft. Passenger- related facilities and structure (like seats and carpet flooring) is take out of the as it does not come in handy for a cargo freighter. This is to make room for the installation of the new freighter equipment. With the removal of redundant material it creates space for the cargo. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 2.4. Fitting of cargo door The front-end of the fuselage section is opened up in 2 stages for the installation of the cargo door. The upper frame shell is held at its position and is secured by riveting the frame to the fuselage. The old lower frame shell section is substituted with a new lower frame shell that is lowered into the prepared cut-out location and incorporated strongly to the airframe. The frames forward and aft of the cut-out are entirely replaced by reinforced frames. After the installation of the frames, electric components and hydraulic systems are added for the cargo door to operate with ease. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online].

Installation of new flooring The normal flooring on a passenger aircraft cannot be used. Hence, the flooring on a passenger plane has to be removed and reinforced with a higher strength floor to resist heavy cargo loads. To move the cargo in the aircraft easily, ball mats and roller tracks are installed onto the cargo flooring. With the new flooring the aircraft can carry more load and be tough at the same time and move the cargo within the aircraft easily.(SPG Media Limited, 2010.

Final checks after conversion Once the body of the aircraft has been converted and all thatà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s left to do is to do a final check on the whole aircraft. Firstly, the aircraft avionics is adjusted before tests are carried out. Thereafter, the customer inspects the flight to make sure everything is in working condition. However, before the aircraft is handed over to the customer the documentation for the conversion is finalised. With all these procedures done, the P2F conversion is complete. (SPG Media Limited, 2010. Airbus A310-200F Freighter Aircraft-Aerospace Technology [online]. Available from: http://www.aerospace-technology.com/projects/a310-200f/) 3. P2F conversionà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s cost impact 3.1 Replacement of ageing Freighters by P2Fs. Since the current condition for the economy is not at a very healthy condition, many aero- logistic companies would scout around for second hand cargo freighters. However, second-hand freighters have now reduced in numbers so drastically that most of them will stop flying within a few years. Hence, P2F conversions will help solve the problem of ageing cargo freighters in the near future. In 2009, airbus presented their 20-year forecast of their future freighter fleet. In their statistics shown in Fig3.1, Airbus emphasised on P2F conversions as the way to go to solve the problem of freighter insufficiency Therefore, by 2028 more than half the freighters around the world will be P2F converted. This is because P2F conversion requires low cost, shorter time and less material than manufacturing a freighter from scratch, making it a cost effective solution. (J. Leahy, L. Rouaud, 2009.

Demand of P2F aircrafts P2F conversion will take the freighter industry to a whole different level. In addition, the wider range of freighter types from P2F conversion will create a new generation of small jet freighters (e.g. Airbus A320 P2F).Besides that ,majority of Airbus freighter demand will be aided with P2F conversion as 96% of freighters in 2028 will be P2F aircrafts. This shows that the future of the P2F conversion industry will have a bright future. (J. Leahy, L. Rouaud,2009.

Benefits and limitations of P2F conversion Despite its many advantages such as its ability to save money time, material and manpower needed. Alongside, it helps extend an aircrafts life and replaces ageing freighters in the market. However, its disadvantages include acceptable use of market price as well as availability of aircraft. The next few paragraphs will explain and elaborate more on the benefits and limitations of P2F conversion. 4.1 Benefits 4.1.1 Saves cost Companies around the world who are looking to purchase freighter cargo aircraft would most likely try to save up on anything they can save on. One of the benefits of P2F conversions is that it helps companies save money. A P2F converted aircraft costs nearly one third of a freighter aircraft made from scratch. Since ità ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s just part of the aircraft that is reconstructed, it will help save cost on the amount of material used. When there is less work to be done, less manpower is needed. Hence; they can save cost by employing fewer engineers to work. Therefore, P2F conversions help save money for companies. (According to Phillip Securities Research (2005), initiating coverage Singapore) 4.1.2 Extends aircraft life A P2F conversion helps extend an aircrafts life span as well. When an aircraft is almost reaching its age of retirement it can either be scrapped or reborn again. In this case the aircraft is sent to companies that deal with conversions. The old structure is replaced with new structure in order for it to fly safely. Therefore, P2F conversions help extend the lifespan of an aircraft.(EADS media centre, Rising (like a phoenix [online], available from: http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500HYPERLINK http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=noHYPERLINK http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=nowidth=1024HYPERLINK http://www.contentforce.de/iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=noHYPERLINK http://www.contentforce.de /iptv/player/macros/_s_eads/_x_s- 35848193/mediacenter.html?height=500width=1024attrs=scrolling=noattrs=scrolling%3Dno) (SIA engineering company websiteprovides information on what P2F conversion is) 4.2 Limitations 4.2.1 Acceptable used market price P2F conversions serve as a form of investment for airline companies. If the cost of the conversion is more than the proposed price to sell the aircraft, the owner selling the P2F converted aircraft will incur a loss. In addition, different models of aircraft go through different kinds of conversion processes. Hence, the standard of quality and the workmanship to set prices for the P2F aircrafts vary widely, which might lead to underpriced P2F planes. (Hamilton, http://museair.googlepages.com/ThePassingofanUnrecognisedIndustryGi.pdf , 2007) 4.2.2 Airframe availability In order to perform a P2F conversion, there must be available airframes. The airframe needs to be from an airworthy passenger jet which is not in service anymore. If not, it would make no sense just to make an aircraft and convert it. Therefore, the number of used jets there are out there is limited to availability. (Hamilton, http://museair.googlepages.com/ThePassingofanUnrecognisedIndustryGi.pdf , 2007) 5. Conclusion The P2F conversion procedure may seem simple to digest. However, it is much more sophisticated compared to the other areas in the aeronautical market. Regardless, the freighter market is shinning their spotlight on P2F conversions to give old passenger aircrafts a second chance to fly again as freighters. In addition, P2F aircrafts are able to perform almost as well as new freighters made from scratch. No matter how advanced P2F conversion gets, there are limits for the acceptable used market price. Otherwise, the conversion will result in heavy loss financially. 6. Recommendations P2F conversion is a very profitable market to invest in. Companies dealing with P2F can take one more step by making use of more advanced technology when they are converting aircrafts. It can help save cost by using less material and maybe even with efficiency. Therefore P2F conversions can take one more step ahead by doing more research in this industry as there will be a rise in demand for freighter aircrafts in the future. III.

Religion Essay -- Philosophy, God

â€Å"Truth, in matters of religion, is simply the opinion that has survived,† was a statement made by Oscar Wilde. (Dawkins, pg. 222) In Richard Dawkins book, â€Å"The God Delusion,† regards the argument of the supernatural being in religion being not feasible. Richard Dawkins proposes his argument â€Å"with rigor and wit, Dawkins eviscerates the arguments for religion and demonstrates the supreme improbability of the existence of a supreme being.† (Dawkins, 2008) Moreover, the author uses vital assessments by allocating the origins of the religion, analysis of the Darwinian natural selection and other metaphysicists that are the contemporary reasoning for phenomenal causes, and the justification of God’s existence. Therefore, the purpose of this novel is to question and scrutinize our religious beliefs. This was shown when Charles Simony, a professor, had said, â€Å"This brilliantly argued, provocative book challenges all of us to examine our belief s, no matter what beliefs we hold† (Dawkins, 2008). Thus, this book is written for people who want to engage in the contemporary world of religion and science. An acknowledgement made by Seed stated, â€Å"A powerful argument for how to think about the place of religion in the modern world. It ‘s going to be a classic† (Dawkins, 2008). In addition, this book would most likely attract atheists because of the challenge of God’s existence in religion through the examination of the roles of religion and scientific explanations. The Economist stated, â€Å"Everyone should read it. Atheists will love Mr. Dawkins incisive logic and rapier wit, and theists will find few better tests of the robustness of their faith. Even agnostics, who claim to have no opinion on God, may be persuaded that their position is an unte... ... authoritative beliefs called â€Å"doctrine†), practices (including formalized rituals), and social institutions.† (bowen, 2011) There are many atheists within our contemporary society especially in North America which the debate of religion and science more prominent. In addition, within this book he uses many notable scientists and significant figures that are excellent proofs that support his argument. In my opinion, overall, the book was an eye-opener and the content was very engaging. In addition, when reading this novel, I felt like I agreed with some of the statements that Dawkins had proposed, in n particular, the natural selection of Darwinan theory. Therefore, this book is very persuasive and puts a new perspective on religion. Overall, the author reached their objectives because he was very convincing and included support and evidence throughout the novel.

Problem Solving and Resourcefulness

RESOURCEFULNESS By: Edgardo Eleccion ( GCCNHS) For many times in our lives, we are often tested in our values and skill of being resourcefulness. Oftentimes, this is more considered as a skill than a value. A person with a gift of resourcefulness is far more advance than those who have none. Definitely, most of the successful individuals in the field of business, education, arts, medicine, politics, communication, religion and others possess the inherent or acquired skill of resourcefulness. However, what is really this skill of resourcefulness? Iannarino ( 2010) defines resourcefulness in his blog as the ability to find a way to achieve your goal or to make one. This is especially true when the goal is difficult to achieve and when little or no direction is given. Resourcefulness is the ability to think creatively, to generate ideas, and to identify alternatives. Resourcefulness is also imagination, the ability to visualize how something could be achieved when there is nothing there but the vision. According to Cindy Quarter eHow contributor, being a resourceful is the ability to approach a problem in different ways. It requires the ability to be creative and pursue a solution from one or more than direction. It is not built in ability but it is learned overtime from the variety of experiences. To be able to develop this into our children, they should be exposed to a situation that requires them to be resourceful and that will provide them the opportunity to succeed. Kids will self-confident and acquire problem solving skills as a result of engaging in activities that result resourcefulness. Games that requires resourcefulness help children to gain creativity and persistence in a fun in an entertaining way. Teachers in the secondary should help high school students develop their resourcefulness in them. They should expose these young minds into a worthwhile and engaging classroom activities everyday and make positive feedbacks after such activities in their everyday lessons for a day to day improvement to surface their individuals resourcefulness. This will prepare these youth into the next stages of their life ahead on how to deal problems along the way in different way around with less pressure. The role of teachers in the classroom is vital in nurturing the students’ skill necessary in building a kind of life intended for them in their future. This will not be seriously taken by the students at their younger years, but when the world dictates competition and pressure, there surfaces the skill they have learned in the classroom situation. Resourcefulness can not be learned in one day as Rome was not built in one day too. It needs constant learning, constant training and constant sacrifices. It needs several exposures into several competition, tasks and challenges along the way. The constant exposure that lead to experiencing a situation that emerge creativity will help a certain individuals to grow and become a better person ready to face the next layers of life’s challenge. In the world of work specially in business and education , resourcefulness is the crucial skill one must possess. A teacher with this skill has great advantage in terms of making his strategies in teaching and his materials a worthwhile and more fantastic to his learners. Moreover, it helps him prepare his teaching aids with less money involved. In the field of business, a manager having this skill can enter into competitive world and able to go beyond the expectation the corporation is aiming for. In real life situation, resourcefulness helps an individual in solving his own problem in different way in which others never ever think of. You may be in business, education, arts, communication, politics, and religion, resourcefulness is necessary in building up the new you. Edgardo Eleccion is a secondary teacher of Gingoog City Comprehensive National High School ( GCCNHS) Gingoog City, Philippines. He is a Values Education Teacher.

Obamacare Will Impose New Health Coverage - 963 Words

Obamacare will impose new health coverage costs, the employer mandate, compliance regulations, and new taxes on all businesses. Altogether, these constraints will dramatically affect companies’ per-employee costs, desire to provide health coverage, and motivation to grow in terms of both income and employment. Further Burdening Businesses. Obamacare is likely to exacerbate many of the concerns and costs that are already burdening businesses—particularly small-business owners—in at least four ways. 1. Higher Health Care Costs. Obamacare does nothing to reduce the continually increasing costs facing businesses that provide health insurance coverage. In fact, Obamacare’s wide variety of benefit and coverage mandates—combined with new taxes, fees, and penalties—will increase the cost of providing coverage. The increased costs of health insurance might lead employers with fewer than 50 employees to drop coverage if they currently offer it, as there is nothing in Obamacare that would prevent them from doing so. Employers that do offer coverage might respond by changing their health plans to accommodate the cost increases. For example, UPS has restructured its coverage to exclude the working spouses of its employees. The company expects this to affect 15,000 employees for an annual savings of $60 million. UPS very clearly cites additional costs imposed by Obamacare as a contributing factor in its decision, listing several Obamacare provisions that increased their costs.1 2.Show MoreRelatedThe Middle Class And The Affordable Care Act1385 Words   |  6 PagesWhile researching the topic of the middle class and the Affordable Care Act (ACA) otherwise known as Obamacare, I found many articles about the impacts of the ACA on the middle class.
