What is a Turbofan Engine? Most used engine for commercial aircraft. Is essentially a turbojet engine with a large intake fan at the front and a bypass section around the outside. Bypass is where a proportion of the intake is allowed around the core of the engine. Turbofans are more efficient than jet engines and more fuel economical. The central core consists of: A low/intermediate compressor A high pressure compressor Combustion chamber High pressure turbine Low pressure turbine Exhaust funnel Alex Humphrey

Rolls Royce Trent 1000 3-spool design Thrust-to-weight ratio of 6.01:1 Powers the Boeing 787 Dreamliner Been in commercial use since October 2011 350kN take off thrust created Bypass ratio of 10:1 Alex Humphrey

General Electric GE90 Uses a double spool system Most powerful commercial engine available Powers the Boeing 777 using only two engines Capable of producing 590kN of thrust at take off Use of composite materials in the fan blades Commercial use since 1995. Alex Humphrey

Overall Conclusion In my opinion GE create better engines because: They have a greater proportion of the overall market share. The engines are more durable and better quality. GE’s vast revenue, allows them to invest more in R&D. GE have a superior production centre and process. They use Carbon Fibre Composites, which have more desirable attributes. Alex Humphrey

The Research I have Undertaken In order to collect unbiased and valid pieces of information I: Used many websites to validate my facts and statistics Used press pages to ensure I had the most recent information Attempted to email the companies to get more validation however I am yet to receive an email. Used university notes to get the most detailed facts to back up my arguments. I went through all these stages to ensure that my argument was as unbiased as possible and the facts tat I was collating were genuine and not manipulated. Alex Humphrey

Time Management I have learnt that time management is key for an extended project. At my mid-term review I realised I was a long way off my first projected plan so I altered my time scale to achieve the deadline. In hindsight I should have followed my original time scale as this would have meant that I wouldn’t of had to sacrifice other commitments Alex Humphrey

What have I Learnt? The main points I have learned are: Plan, review, do. Was a very useful moto for me whilst doing my EPQ and meant that I was always sure of what I was going to do and when. I have learnt to begin the project sooner as this alleviates stress further down the line. I have also learnt to not be afraid to send emails to anyone and everyone who can help as they are most likely going to be happy to help. Alex Humphrey

Personal Review I am very happy with my project, as it is highly detailed and reaches a valid conclusion, which I would feel confident talking about to anyone. I have achieved a greater confidence to approach people to help me in my EPQ. I have learnt how to plan my time efficiently and manage if I deviate from the plan. I am also pleased as this really helps me with my application for a higher apprenticeship in mechanical engineering or aeronautical engineering, as it shows my interest in this subject. I have really enjoyed learning about the aeronautical industry as well as the satisfaction of completing this task. I have also enjoyed putting all my skills that I have learnt at school into practice. Alex Humphrey
