The Boeing 787

September 25, 2011

Boeing is in the process of launching (finally, after delays) its latest aircraft, the Boeing 787 Dreamliner. This is the first new major jet launched since the Airbus A380, and of course, has me interested in many ways.

Of course, on a personal-professional level (if that term makes any sense, which I have a feeling it doesn’t—anyway, I work with composite materials, remember?) the B787 is mostly made out of composites. Mostly out of carbon-fiber laminates; some out of carbon fiber sandwiches—use of metal (titanium and aluminum) is minimal.

Second, I just love the wing design. The sweep and curve upward of the wings is just beautiful. Also, it is a vast improvement over the last generation of wing-tips, which looked as if from a design perspective they were a later ‘add-on’ to a previous, flat shape. Here, finally, is a smooth, elegant, downright beautiful wing shape!

I also found this link to the B787’s design highlights. It’s an informative page, do check it out. (For information about the composites being used, go to Visionary Design→Composites.)

From the link above, I learn (among other things):

  • There is a very futuristic HUD (Head-Up Display) in front of the pilots which combines what the pilot actually sees with other useful information that the pilot needs. I’ve seen things like these in Fighter Aircraft simulations, but is this the first time it’s being used commercially?
  • The B787 is not a very large aircraft! I had inherently assumed that the plane would be B747 or A380 scale (i.e. a pretty big plane), but it’s not—it can carry a maximum of about 300 passengers, compared to the B747’s ~400 and the A380’s 525 in three classes.
  • The internal air pressure of the aircraft will correspond to a lower altitude (6000ft, as compared to 8000ft in earlier aircraft), and will have higher moisture content—meaning a more comfortable flight!

Now, what remains is for the major airlines to buy these and put them into service.
