Cars are not the only industry “going green”. Boeing is reinventing it’s smaller and older 737 airplanes into a larger, sleeker, and more fuel efficient airliner. What was once a narrow bodied plane, primarily used by Southwest Airlines, United Airlines, and American Airlines, only able to carry between 80 and 200 passengers, first introduced in 1968, with only two engines designed specifically for short routes, has been completely reimagined into the Boeing 737 MAX.
The first step in its revolution were the Airbus A320 and the Airbus A320neo which were considered an alpha and beta version of the reimagined engine in addition to a rearranged seating to a single isle assisting the engines’ better fuel economy. Two airline companies noticed the improved airplane and began using them, and the secret was out. The entire airline industry began inquiring about the Airbus and the Neo, but rather than making more of those models, Boeing announced the “Boeing 737 MAX project”.
The Boeing 737 MAX will have body modifications described as a “clean-sheet design” including advanced technology winglets, that were found to be made of aeronautical aluminum after an interview with Boeing engineers, The twin engines from ’68 will be replaced with the twin fuel-efficient CFM International LEAP-1B engines. LEAP is an acronym for Lead Edge Aviation Propulsion. That means this engine is made of a better compressor, because it has a one piece fan, which can be made from the same titanium strength aluminum discussed in a previous blog, allowing for fewer parts and 8% more efficiency. It also has a better combustion system allowing for roughly 16% better fuel efficiency.
Currently the projections for the Boeing 737 MAX are so provocative, that Boeing already has 900 planes ordered, to be delivered by 2017, but this is just more reason for Boeing to continue moving future projects onward and upward.
