Aerospace Engineering: Boeing 777
The product I chose to research was the Boeing 777. I chose this because Aerospace engineering is what interests me most. The purpose of the Boeing 777 is to take people from place to place at a faster speed then by car or train. The Boeing 777 is a long-range, two-engine, wide-body commercial airliner. It is the world's largest twinjet plane. It is also the first airplane to be designed completely by Computer Aided Drafting.

The primary material to make the Boeing 777 is Aluminum 70 percent of the overall structure is aluminum. Other materials used in production include; Steel used in components where strength or part of life is most important, such as landing gear and structural elements, as well as fasteners. Titanium is used for exterior parts where weight or high temperature is important. For example around the engine bays where heat is imminent. Composites are commonly used for less structural areas such as panels and fairings but may also be used on tail surfaces or interior floor beams. Some of the other materials used are rubber, plastic, and fabric, but are primarily used in the cabin interior. Boeing used these materials instead of other alternatives due to strength and longevity. These materials are easier to mold into compound

Boeing became the first commercial airframe manufacturer to use the concept of building jetliners. While using this process Boeing found that being able to have a moving assembly line reduced the time from start to finish. Additionally, they discovered that it cut the overall cost of production. The moving assembly line is designed to highlight any problems and allowing for workers to stop the line to fix the issue before proceeding. The process forces workers to look at all waste and get rid of it. Allowing for a more lean production process in the
