Solid Volume Of Airframe/Engines?

Tue Feb 09, 2010 11:54 am

Discounting all the empty spaces (cabin, fuel tanks, bypass ducts, etc) and taking into account all the solid parts only, what (approximate) volume would:

- a modern high-bypass turbine engine like the CFM56 occupy; and
- a modern airliner like the 777 occupy?

I suspect it would be quite low...

Very very rough estimate: let's guess that the mean density is about 2600 kg/m3, corresponding to Al-Li alloy, which makes up quite a bit of the total weight on a modern aircraft. Other components have greater density (steel...), but others have less... With an empty weight of about 150000 kg (including engines), the volume would be 58 m3.

That was for some quick numbers. I have no idea what the mean density is, looking at the percent in weight of each material we could be closer, and I believe that information should be easily available. Maybe I'll give it a try later
