Re: Something wrong with Boeing's safety culture?

Gasoline is highly volatile whereas Kerosine is not. And when I say generally speaking, I mean every metal wing certified since the A330 is required to be, so really... Yeah but the 787 and 77X do not have a "generally speaking" metal wing as their wing is not metal. Also even though Kero...

Is that accounting increased fuel burn due to higher weight? If you assume 20t extra (from MTOW-20t to MTOW), and we assume 0.3% increase from weight (it's been mentioned somewhere it's 0.4%, but also 0.28% I believe for A359, 0.3% seems fair assumption), you need 6% more to achieve the very same r...

Another thing to consider is that if Boeing does the NMA now and the FSA later (say 2030+ EIS) the 2 will be competitors if the FSA covers the 150-250 seat single aisle market. Not if the FSA is optimised for shorter range. Optimising a FSA design with a MAX8 sized cabin to say 3000nm instead of 40...

Boeing can not launch anything that takes away orders from the 787 without risking near term losses due to write offs of the deferred production costs.

Re: Any leaks, ideas, or otherwise: What is Airbus' next clean-sheet aircraft?

We also have computers that are slightly more powerful than the 1950's - yet Kelly Johnson and the Skunkworks were able to do the SR-71 which is pretty non-conventional and a quasi lifting body with slide rulers back in the 50's. A prototype to prove the concept could be done very quickly to prove ...

Re: Any leaks, ideas, or otherwise: What is Airbus' next clean-sheet aircraft?

No one really knows how they will do it - all we think we know is that NMA was strongly rumored to be 7W and Ovalish, as was NSA. Due to the specific properties of Carbon non-traditional shapes can be explored and taken advantage of. It seems like Boeing has been working on this for 10-20 years - I...

Re: Any leaks, ideas, or otherwise: What is Airbus' next clean-sheet aircraft?

We have debated this multiple times - the Rumor is Boeing is using something like half a circle on top and 1/3 of a bigger circle on the bottom - that takes care of a lot of the hoop stresses and the floor compression issues. But how? The largest diameter is not where the floor is, it is roughly wh...

Re: Any leaks, ideas, or otherwise: What is Airbus' next clean-sheet aircraft?

You have not proven (and neither have I) that 6W or 7W has an advantage/disadvantage in terms of weight. 1. on a directly comparative level of circular vs circular the hoop stresses from pressurisation scale with the square of the diameter and therefore for equal floor area (the 7w requiring less l...

Re: Any leaks, ideas, or otherwise: What is Airbus' next clean-sheet aircraft?

Plus you would pick up 50% more space in the belly per M of Fuselage which is a big advantage as well. A 3-3 circular fuselage would be lighter and longer than same seat capacity 2-3-2. So also a longer cargo belly, housing more standard AKH containers and pallets than a undefined wider container. ...
