  • Airplanes

  • are essentially pressurized cylinders zooming through the air 10 km above the ground.

  • They take us to work and on vacation, bring us to family

  • and in general move us from point A to point B faster than any other publicly available transport on earth.

  • Here's how a modern commercial jet aircraft is made:

  • So, it's a beautiful fall morning

  • and I am getting ready to go

  • get on an airplane

  • to go to france to learn about airplanes.

  • I flew to europe to visit the factories, research and design facilities of AIRBUS

  • because they wanted to give me and you a behind the scenes look at their newest airplane, the A350.

  • Here it is!

  • But before the first flight happens,

  • even long before the first rivet is set,

  • a team of thousands of engineers and designers spend years developing the design for both the aircraft

  • and how it will be manufactured.

  • They have to take into account the desired passenger capacity,

  • the range and speed of the plane,

  • passenger comfort,

  • requirements for landing and navigating airports,

  • flight controls,

  • fuel efficiency,

  • how and where materials and parts will be scourced and produced

  • and a million in sundry other details.

  • Over the course of the design

  • engineers use computer simulations and wind tunnel models

  • to test the aerodynamics of the aircraft in its takeoff, cruising and landing configurations

  • and even use scale model engines powered by compressed air

  • to understand the wing engine interaction.

  • Fluid dynamics is freakin' complicated.

  • All of the various systems have to be independently tested,

  • the wing flaps and the landing gear deployment and the engines and so on.

  • They even shoot several dead ducks into the engine at high speed

  • to make sure it can continue to provide thrust if it encounters a flock of birds.

  • Once a plane is designed, the parts --all 2.65 million of them-- have to be manufactured and assembled,

  • some by AIRBUS itself

  • and many like the engines and landing gear by outside contractors.

  • In the case of the A350 aircraft

  • the wing tops and bottoms are made in an additive process using carbon fiber infused resinous tape,

  • which is then cured in a massive oven until it becomes stronger and lighter than steel.

  • Let me say that again:

  • That is going to be an airplane wing --

  • made out of tape.

  • The wingboxes are assembled and fitted with electrical, hydraulic and fuel systems,

  • painted and then the flaps, slats and ailerons --the things they use to steer-- are added.

  • They ginormous tail fin is constructed in a similar fashion.

  • The fuselage (struggles to pronounce)

  • and rear pressure bulkhead are built separately,

  • again out of carbon fiber composite materials

  • and are wired and outfitted with instrumentation and hydraulics.

  • The nose of the aircraft is added

  • and then all the parts built off site

  • are flown by a special and hilarious looking airplane part carrying airplane

  • to the final assembly line

  • where in a single stupendously massive hangar the fuselage pieces are fastened together,

  • the wings are connected,

  • landing gear installed,

  • auxiliary power unit put in place,

  • vertical stabilizer and horizontal tailplane are attached,

  • seats and ventilation and cabin and cockpit interiors are installed,

  • etc.

  • Finally, at the very end, it's time for the engines.

  • They're the most expensive part, so they're put on last.

  • The plane then undergoes in flight testing to make sure all the systems are working as intended.

  • When a new aircraft it being developed, the first few planes built

  • are covered with sensores and tested extensively to the range of their limits:

  • Cold weather,

  • hot weather,

  • high altitude,

  • water on the runway,

  • tail scraping on low speed take off,

  • wing bending strenght,

  • etc.

  • And in addition to this extensive prototype testing, every single plane that comes off the assembly line

  • is taken on its own testflights.

  • Once the test pilots and test flight enineers are happy

  • we're done!

  • The plane heads out onto the runway for delivery to an airline somewhere around the world.

  • When it's running at full speed, AIRBUS' facilities will build ten A350 aircraft every month.

  • That's one plane completed every two working days.

  • It's a pretty amazing feat of engineering, manufacturing, infrastructure and technology.

  • And if there is one thing that I learned about airplane manufactur while visiting AIRBUS,

  • it's that every single part of the process has its own expert.

  • There are airtraffic control experts,

  • seat experts,

  • wing flap experts,

  • wind tunnel engine model experts

  • and even carbon fiber recycling experts.

  • All, so that you and I can get from New York to London in a few hours instead of a few days.

  • I am here in the escape hatch of the AIRBUS A350.

  • Ahh, if there were an emergency I would have to jump out of this place.

  • But I would like to say thank you to AIRBUS for bringing me here,

  • it's been an amazing trip, I have learned so much about airplanes

  • and it's been really fun to see the production facilities and-

  • and to see the test aircraft and stuff like this.

  • So yeah, thank you to AIRBUS for allowing this to happen, I hope you've enjoyed it.

  • I can't believe how big this airplane is.

  • It is huge.

  • I don't want to jump out.

  • Oh, and one more thing:

  • If you'd like to buy an AIRBUS A350,

  • just get in touch with AIRBUS and let them know I sent you.

  • (wink)

  • LOL
