Re: Expert help: Wing aspect ratio/ spanlading vs induced drag

This is why L/D is entirely* based on a plane's 3-d description, independent of its weight. It is true that the Maximum L/D ratio is independent of weight and wingloading, but airplanes don't always fly at the speed that achieves the maximum L/D ratio. When the weight of a plane increases, the spee...

Re: Boeing officially forms program office to flesh out 797 plans

My question is, if 797 is launched to cover the 235-270 pax area, how would that affect the sales of 787-9 and 787-8? Does that leave 787 with only long-haul missions (except for 78J of course)?

Re: Expert help: Wing aspect ratio/ spanlading vs induced drag

Weight will affect induced drag, since weight affects the amount of lift required. A reduction in design weight doesn't automatically mean a higher aspect ratio. Aspect ratio is a property of the wing geometry (span^2 / area). But it does proportionally affect aspect ratio if you keep span and wing...

Re: Boeing officially forms program office to flesh out 797 plans

6 abreast won't be able to hit the capacity target. Upgauging is the main market of the MOM. The half way point between the A321 and the A332 is around 190m2.

But the 787-10 as the numbers show is lighter per passenger and lighter per usable area than the A321. Alright, allow me to ask differently this time, why wouldn't Boeing go for an all new composite narrowbody design that would be similar in size to 757/A322. What are the advantages or disadvantage?
