Control and stability is harder than for a conventional lay-out, although we've come a long way with that. People are sitting further away from the longitudinal axis of the plane, so they're going to be in for a rollercoaster ride whenever you roll the plane. This is much harder in a BWB where people will be sitting further from an exit. Current regs require a plane to be capable of being evacuated in 90 seconds. Lack of a vertical tail saves weight and drag, having your 'fuselage' produce lift saves drag, and as a side-benefit the engines are shielded by the fuselage, reducing the noise for people on the ground. What would be the advantage of this blended wing design over present wide-body aircraft? Just curious. Is there huge fuel tanks right behind them, or is there a passenger lounge in that big area? Hmmm.all the passengers are sitting on the leading edges of the wing. I'm also pretty sure you can make a flying wing inherently stable, so loss of hydraulics or flight computers would be no more catastrophic than on a conventional plane (which is not to say that you aren't in deep doo-doo if it happens). That rumor has some historical correlation to it which makes it plausible.ħ37 - Upgraded 10 times to its current version "MAX", future upgrades very likely for 2018-2020.ħ47 - Upgraded 7 times, the latest upgrade is the 800i series, future upgrades possible depending upon the success of the 777 and 787.ħ57- Upgraded 3 times, currently there are no national medium sized jet aircraft from Boeing other than the 757, many airlines still use this aircraft.ħ67 - Upgraded 4 times, there are no current plans to upgrade the 767 and it will likely get replaced by the new 787 (if they can fix the problems and get past the media).ħ77 - Upgraded 4 times, it remains to be seen if the 747 will continue on its upgrades or if the 777 will completely replace it, future upgrades possible.Īddendum: Another rumor has the 797 to be the next 757 evolution. Personally I don't like the flying wing design for commercial use, for stealth military aircraft its ingenuous but not without its inherent risks.Īddendum: Another rumor has the 797 to be the next 757 evolution. Also the electronic computers that would assist the pilots, if they fail, the chances of the aircraft safely getting back to the ground are pretty slim. The biggest problem with a single flying wing design is when a failure happens, especially a hydraulic one, you lose surface control, this is already a very deadly problem in a conventional aircraft, in a flying wing, its a guaranteed disaster. There have been many test designs other than those 2 aircraft, its just that those 2 were actually known to have flown successfully, many others have tragically failed. Both aircraft were developed in secrecy and both aircraft have unique problems under failure conditions. The only 2 aircraft that have been made and flown in a wing design are the B2 Spirit and briefly the Horten Ho 229.
