Boeing 737 Max Enters the Final Stage of Testing

The Boeing 737 is the newest addition to the fleet of airplanes that this giant plans to roll out. It already has 58 interested clients who have placed orders of approximately 2,869. The first 737 Max 8 was launched in 2015 and the lack of public announcements mainly reflects on the fact that Boeing plans to keep this introduction limited to an internal audience. They have kept themselves busy with technical developments leading up to the unveiling of a piece of machinery that is considered to be one of the finest developments in commercial aviation ever since the airbus A320.

The 737 Max has features such as:

  1. An updated EEC software and upgraded fuel and air-borne pneumatic systems.
  2. An approximately 70 inches long CFM LEAP-1B fan and a custom core with a reduction in fuel burn by 11-12% leading to a drop in operation cost by 7%.
  3. A higher engine ground clearance due to a nose gear extension ranging from 15-20 cm.
  4. Nose wheel alterations will help to accommodate a longer nose gear strut.
  5. The hydraulic system redundancy resembles the 757.
  6. A design modification in the tail cone was made to reduce the drag given to air flow lending a 1% drop in fuel burn.
  7. Composite air foils with upward and downward directed winglets.
  8. Structural strengthening making the aircraft more fuel efficient.
  9. 1-inch LCD cockpit screens to display necessary details in landscape mode.
  10. Techniques to optimize cabin pressure and ice protection systems, in turn reducing fuel burn and improving fuel efficiency in the long run.
  11. A fly-by-wire system that reduces fuel burn and improves stopping distances.
  12. The model is also more environmentally friendly and has a higher sustainability than its predecessors. The design modifications that led to it being eco-friendlier are mini split flap, fan nozzle variations, trailing edges that are adaptive, optimization of flight trajectory, and finally, using regenerative fuel cells.

The Max series will therefore be classified under the 737 family rather than being christened with a new identity. The fact that the 737 has reached its production and assembly phase is an achievement for the teams involved in the process and cause for celebration. The next challenge in its production will be to meet the high number of orders placed, on time. Most deliveries have been promised to be in 2017, but to meet that deadline, the teams will have to keep up the good work and strive to reach the goal in a timely fashion.

The first group of test aircrafts was recently assembled part by part after each component was manufactured by suppliers. This marked a change in the four-year tradition in Boeing manufacturing. Out of the four aircrafts that have already arrived in parts, the first prototype was named 1A001 and is ready for its test flights. The other three are in the process of being assembled. The 1A002 is in its final stages of being out together and is revving to go for its own flight check. Partially completed test stations are present within the cockpit of this model and the water ballast tanks were not visible indicating that this second model of the 737 Max series would be dedicated to test its new avionics systems. The 1A004 will be the most spectacular of all since it will be the first of the Max series to be fully furnished and available with completed interiors, lavatories and passenger seats. Dubbed as one of the most massive passenger planes to date, it will be able to carry 200 people at a time, along with crewmembers.

The testing of the Max series is different since it will also be testing things, which would only be done with an airline. The test would perform test step-climbs to gauge the functionality of the engine. With the Boeing mammoth entering into its final stages of testing, customers are looking forward to introducing this giant to their fleets. Due to its high passenger carrying capability and improved fuel efficiency, it will mean a lucrative investment for interested parties. The profits that companies aim to gain via this investment is far more than what they might have received in the past. The pilot program to introduce the Max series and launch it in air is one worth charting on the aviation industry. The success of this series will largely depend up on how well they can satisfy their claims of efficiency and superiority
