Last week we received the good news that our proposal of the graduate project got approved by HR. This was instantly celebrated with a super delicious apple pie from the lunch restaurant, which also gave us the positive energy we needed to start with the project right away. The purpose of this project is to increase the awareness of GKN Aerospace Sweden (GAS) as an employer among students and young people throughout Sweden but also strengthen the brand awareness of GAS.
This will be done in two different ways. The first one is focusing on the improvement of our participation at career fairs and upgrading the booth. Tasks such as concept development, order a new booth, refine our brochures and look into new giveaways will definitely be included.
The second part of our project is aimed at modernizing the visitor centre here on site, whereas the goal is to make it more compelling to the visitors and deliver a new concept for how it can look like. We have already a lot of creative thoughts and ideas around this topic, but it will be more fun to reveal them later when things are fallen into the place.
The last week it has been full focus on the tasks we have at our departments, especially for me and Elin. We have been busy carrying out internal audits for the Intermediate Compressor Case that we manufacture for Rolls Royce’s Trent XWB engine. An internal audit implies that you go through each operation step in detail and tries to find areas of improvement with the help of the operators’ inputs. As a result, we have spent most of the week out in the workshop and gained a deeper understanding for TIG, plasma and LASER welding, which was super cool and interesting!
As most people say, time flies when you are having fun, it is also about time to start planning for our next rotation and I will reveal mine in the coming weeks. Beside that we will soon begin with our graduate project, which we will tell you more about soon.
We have finally arrived in the land of freedom and started our second activity week, which is in California. The first few days were spent around Los Angeles, where we took the Monday to visit one of our sites in Santa Ana, roughly an hour by car from downtown LA. We were greeted by the site HR manager, Leslie Gelle, who took us on an educational tour of their facilities and workshops. The GKN Aerospace Santa Ana site manufactures honeycomb panel structures. In principle, these are made of two thin metal sheets with a grid in between, which resembles a honey comb. The result works a bit like a thermos, and minimizes transfer of heat and noise to the surroundings.
The parts that are made using honey comb plates are predominantly located in the rear part of the engine. Besides the tour, we met site manager Scott Gulyas for an interesting discussion about the future development of the site. We also took the chance to catch up with one of our fellow Global Graduate colleagues, Honi Ahmadian-Tehrani.
Hope you have had a good week so far and not a week that has been as dull as the weather we have had here during the past few weeks. We even had a new record for the least total hours of sunlight at the west coast during the month of November. According to the statistics, the average is around 59 hours of sunlight, however for this year it was only 10 hours! 🙁 But luckily, today, the sun finally came back and shone over Trollhättan and energized us right before the end of the month. 😀
In comparison to the previous weeks, this week has been significantly calmer. It gave us the opportunity to spend more time at our home departments and focus more on projects. Beside that we arranged a lunch meeting with the Flying group, which is a community for all current and previous trainees at GKN Aerospace in Trollhättan. It turned out to be very successful and many people attended and showed their interest in us.
I am looking forward to meet them again at the Christmas mingle that we will host next week!
A new week of course means a new blog post and it is finally my turn to be writing it! Even for this week the days have been running away as we have been busy attending the last Training Days courses. A course most of us found it very interesting and valuable was Jet Engine Theory. It was a whole day course that went through the basics of how a jet engine works, especially the RM12 engine which is equipped on the Swedish fighter aircraft Gripen.
Some of you might already be wondering “how does such powerful engine actually work?”… But don’t worry! I am about to answer that question in a very simplified way. 😉
The first stage that the air passes through is the fan, which is mounted at the very front of the engine. It carries on to a low pressure compressor that is comprised of three turbine stages according to the picture below and then continues further to a high pressure compressor. The purpose with these stations is to compress the air, where both the pressure and temperature will be increased. Thereafter the air is directed to the combustion chamber, where it gets mixed with the fuel and then ignites, resulting in a very hot gas that exits the combustor. It then passes both a low and high pressure turbine (Recognizable?) that have the main function of powering the different compressors and the fan. In order to leave the engine the gas will have to flow through a convergent nozzle that accelerates the gases, providing thrust to propel the aircraft.
I hoped this post gave you a better understanding of jet engine. See you soon again! 😀
