How do 737
• How do 737
11 days - that is how much time is needed to collect a brand new and sparkling Boeing 737, the most popular passenger aircraft in the world! Total factory in Renton collected 38 aircraft per month, and the very line 737 produced since 1967! Customers have already delivered more than 7,600 aircraft ... And 3000 boards ordered and awaiting delivery and assembly! At the same time on the assembly line atmosphere is more relaxed than-stately. Visually, no one is in a hurry, because the most important thing - it's safe, that's where the cost of failure is very high. Therefore, each employee of the assembly line operates in a very comfortable pace, without haste and fatigue.
In this feature, I invite you to the factory, which collects 737, because all you will almost certainly fly on this plane at least once in your life!
But first factory layout around Seattle. In Renton collected 737, and then the plane flies at Boeing Field Airport, where after a series of test flights is its transmission to the customer. Haul aircraft is collected and delivered to the customer in Everett, there is a center for tourists, the plant can be passed as part of the tour.
The production complex in Renton includes production lines, busy assembling the single-aisle Boeing 737 NG aircraft and modifications. Production in Renton was deployed on the eve of the Second World War. Here were created the famous Flying Fortress Boeing B-17.
After the war, in 1952, with factory stocks descended first jet passenger plane Boeing 707. It developed a series of subsequent modifications and Boeing narrow-body aircraft: -707, - 727, -737 and -757. Today, the production program Renton 4 are modified Boeing 737 NG aircraft. There will also be running the latest version of the assembly of the aircraft Boeing - 737 - 737 Modification - MAX.
consolidation of production in Renton was held in 2003. All engineering and support units have received a residence permit in the areas immediately adjacent to production. Such rearrangement increased the efficiency of management and interoperability. In this production area declined by more than 40%. Production is organized as a moving assembly line, in fact, - a first conveyor assembly of passenger aircraft in the world.
Note the following two pictures, they are hanging at the entrance to the production. First made in the 80s, the second - modern konveyernayaskhema work. The entire assembly line is moving continuously at a rate of 5 cm / min!
The fuselages for Boeing 737 built in Wichita, Kansas. Transported by rail over a distance of 3218 km. Delivery to the plant in Renton takes about 8 days.
In one of the reports earlier someone said in the comments - why the fuselage of the Boeing uniformly green, while Airbus has different shades of green. Answer: a Boeing 737 fuselage assembled all in one factory, Airbus in different parts produced in different plants. However, the larger Boeing also on different.
The rhythmic production of aircraft was made possible by the implementation of the virtual model of each assembled airplane. Long before the bookmark airplane virtual model provides a perfect assembly of all components and accessories (kitchen, - from Japan, the chair - from Italy), in accordance with a variety of customer requirements. Here fully implemented the principles of "Lean Manufacturing". On the other hand, it is possible to shorten the entire cycle from order to delivery with a 2 and a half years to 11 months. Each month, from the factory gate go up to 38 Boeing -737 aircraft and only in 2012 were delivered 415 aircraft to customers. Now one aircraft is collected for 11 days, with plans to reach the mark in 10 days! And it is not due to the increase of number of employees, or areas, namely by optimizing the assembly process:
The new 737-800 for FlyDubai. It is for this airline December 16, 2011 7000 Boeing delivered the first 737 minutes!
Almost all - it is handmade!
move to the second line.
In general the height of the pavilion with the assembly line 737 is 33 m, width - 230 m, length - 340m.
The gap occurs installation of vertical and horizontal stabilizers:
The territory is huge - so for crossings employees use bicycles:
In the center there is the installation of galleries, hydraulics, chassis,
The following items are mounted interior and seats, toilets, luggage:
And finally, the last position before the roll-out - engine installation CFM:
Then roll out the plane and transported to the next painting workshop, but he makes the first flight being completely unpainted! Here the aircraft for the Chinese returned to the assembly hall for further refinement units after test flights:
And next to the lake, a beauty!
After the rollout of the aircraft for 5 days towed to the airfield Renton, it's just a couple of hundred meters from the assembly shop. Here comes refueling; performing pre-flight tests, including testing procedures engines. The aircraft performs its 1st flight in Seattle Center to supply airfield Boeing Field.
Then performed flight tests, which uses Boeing pilots and pilots of the customer and takes all of about 7 days.
In the workshop of painting me neither Boeing nor Airbus could not get there, very much like, but I had a lot of things to wear, and time, as usual is not enough ... Usually it takes about 190 liters of paint painting length 737. After drying, weight of paint on one plane is about 113 kilograms, depending on the paint application scheme.
The next reportage I will talk about what he saw at Boeing Field airport.
For example, a brand new 737-900 for the Ukrainian UIA, has just returned from his first flight from the factory in Renton Boeing Field:
70% of all sold by Boeing civilian aircraft accounted for the family 737. It is here that there is a transfer of the first of forty Boeing, UTair has ordered that as part of the renewal program and the completion of the fleet.
Thank you for the tour!
Every second in the world in the sky in the air are more than 1,700 Boeing 737s! Monitor "live", you can view each type of aircraft of those that are in the air. At the time of my visit it was: 787 - 14: A380 - 80.
