Ratio Of Engine Diameter To Fuselage Diameter

Tue Jun 26, 2007 11:37 pm

Now, with the first pictures of the 787 unveiled, Isn’t it interesting to see how the ratio of engine diameter to fuselage diameter of twinjets has developed within the years?

From the 737-200

and maybe the worst example, the Bac 1-11:

Well, although it’s not a twinjet, some people say this was a setback (no, I will not repeat that “H”-word, now)

But this has been corrected about ten years later:

and finally the godfather of big engines, the B777

and the 787 as shown in the current thread. Maybe someday the diameter of the engines will overtake the diameter of the fuselage?

The proposed 737-1000 with the engines from a the 777 would have engines larger diameter than the fuse Big grin

I had to think about this classic:

I guess we're moving to high-wing designs.  Smile

Argh: the thread moved before I hit the post button.

While a turboprop rather than a turbofan, the rotors on the V-22 Osprey are 38 feet in diameter, which I believe is wider than the cabin.
I have a three post per topic limit. You're welcome to have the last word.

When does a turbofan become a ducted fan? I see the size getting much larger, personally. Somewhere between the size of today's turbofan and unducted fans. I don't know, though, if we will see them move to the old T-tail configuration or towards a high wing design. Perhaps we will see them on the new 737 and 320s.
