Good captions.

Why does the 'Silent' Aircraft concept design look like this?

Kach try for Caption 1 - Fish often make passes at girls who wear glasses!!

Caption 2 - Guess whos not waxing their legs!

Caption 3 - Just wait until I get my hands on the inventor of that hair growth lotion!!

 

Because ... "
"In addition to performance, comfort and capacity, the (Boeing) BWB concept has an inherently low acoustic signature. Exhaust noise will not be reflected off the wing's undersurface. There is little additional airframe noise caused by complex mechanism, such as slotted flaps. The aft location and staggered positions of the engines lessens the possibility of shards and debris from a failed powerplant penetrating the pressurized cabin or fuel tanks, destroying flight controls or causing the remaining engines to fail. Compared to conventional cylindrical tube fuselages, the center body pressure vessel of the BWB is much stronger, thus improving chances of survival in a crash."

"... when Boeing absorbed McDonnell Douglas, they also acquired the thinking of three more innovative design engineers, R.H. Liebeck, M.A. Page and B.K. Rawdon, who were working on the Blended Wing Body (BWB) transport of the future. (http://www.boeing.com/news/releases/mdc/97-158.html)
If ever a design represented innovation matched with utility, this one is the embodiment of that concept. According to intensive, well-reasoned calculations, the aircraft they propose would carry 800 passengers over a 7,100 nautical mile range and be ready to enter service in the year 2010. Quite an accomplishment considering that its fuel burn will be 27% lower than its conventional Airbus A3XX rival, with a take off weight 15% lower. Empty weight will be 12% less. It will only require three instead of four engines, and will match or exceed conventional performance, despite having 27% less thrust. Those factors combined with 20% better lift/drag capability translates to the phenomenal savings in fuel already mentioned. ... In layman's terms, the low effective wing loading of the BWB meant that exotic high lift systems are not needed. A leading edge slat is necessary on the outboard wing, but all trailing edge devices are simple hinged flaps, which also serve as elevons. Low wing loading reduces control power demands. The small winglets provide primary directional stability and control, and split drag rudders, similar to those found on the B-2 bomber, are used for low-speed, engine-out conditions. ...
Will such an aircraft ever be built? That's the decision the manufacturer will have to make. But if a large subsonic aircraft to take the place of the 747 is really needed, it appears that the BWB concept offers the most for the necessary investment. It's lighter, more commodious, more fuel efficient, requires far less power, and is certainly more aesthetic in appearance. True, looks aren't everything, but that old aviation adage still holds true, "If it looks good, it will fly good," and the BWB aircraft, in addition to much improved economy, simplicity and handling, certainly has any potential flying watermelon beaten hands down."

Boeing decided to put the BWB airliner on hold sometime around 2003, but they have done some model testing with the Air Force and in the NASA wind tunnel. Given the likelihood of higher fuel costs and environmental pressures, this may yet be built.

 

Good one, Mike, I'm proud of you!

funny as hell, can't stop smilling on that one

 

Cheers Charlie; one tries mate!

 

Is it just me or is that supposed thumbnail of the 797 against moon lit water realllly a shot of the a bikini clad "Y" section. ie a smiley face on the mound of venus????????

 

It's just you, Roly. No one on this forum would ever put a sexual interpretation on any photo!

 

OK, so this thread has been inactive for a few days. Here we go again!

"The technology of appllying air gasbag to the launching and landing of ships overcomes the restrictions of traditional slide board technology which is commonly used in building small or medium size ships. After years of practice and accumulation of experience, we have developed this technology from facilitating the launching of only 100 ton ships to current 7000 ton ships."

Thought of putting this in "Dumbest moves ..." thread, but it's also a good random video, even a boat theme, sort of.
