1970s Boeing Advanced Bomber Studies

The Boeing ABC prop fan is the most interesting of the concepts. Is there a good source of information on the Boeing ABC prop fan concept? What was the advantage of the prop fan design over the jet engine powered designs?
 
One could theoretically duct a propfan? :eek: Or does it become a very high bypass turbofan in that case?
Of course, you would need a sufficiently high fuselage volume.

RCS being radar cross section?

Exactly. This concept may be usefull when your goal is to have the aircraft for the low intensity conflict with the weak air defense and you need quiet low weight subsonic plane with great range.

Almost every new engine for the big civil airliner is the high bypass turbofan. To duct the propfan... hm, there were some tests in Russia recently on the Il-76 but I am not sure about the results. With the relation to Boeing in that era, they probably also considered to use UDF (unducted turbofan) engine. However not any of this concepts can survive in heavily defended territory, so they couldn't meet the coming ATF requirements.

Notice that it says Boeing "X" in the bottom left corner. ;D
 
Well, there must be a Secret Projects fan in the postal administration of Gambia.. An Honorary Membership for her/him (if not yet here ...) :eek:

I wonder if they produced this stamp for foreign collectors to get hard currency?

...Show me a third world nation that doesn't do that. Hell, even the USPS does this with dozens of commemorative stamps each year. After the fall of the Evil Soviet Empire, the Russians got into the game with a commemorative pair block featuring Groucho Marx and John Lennon. It became the largest boost to the post-Empire Russian economy in the first year after the failed coup led to the downfall of Communism in Russia.

Hopefully you foreigners will get the joke...

LOL, I wasn't aware that the Russians actually has a sense of humor :)
 
On the AIAA site, paying a modicous amount of bucks.
 
Hi,

there was some different between those two Boeing Delta-wing
bombers,look at the cockpit and the wing,and those two artist
drawings were posted in the same issue.

Moderators, I poked around with the search engine but couldn't find a suitable home for these pictures - the ATB thread may be the closest thing, although i swear i saw some of these on this forum before. The captions shed some light on the concepts.
The following pictures come from AvWeek, circa 1979. There are several Boeing and Rockwell concepts, the latter being Raymer's.

Merged and consolidated topic. The design, that Stargazer2006 originally posted is Boeing supersonic tailess airplane and is already covered here.
 
Thanks Matej. Allow me to say once again, though, that the Rockwell Delta Spanloader is also known as design D645. This may help in future searches.
 
Actually it's already there. And this thread (which I hadn't visited previously) describes ALL pre-ATB bomber designs by Dick Raymer as falling under the D645 designation, however different they may have been. The Delta Spanloader was D645-4A.
 
From Flieger Revue 7/1981,


here is a clearer artist drawing to Boeing Advanced Bomber Concept.

This looks like the Advanced Mission Adaptive design posted in this thread:

Previously, we only had a black and white image of this concept:

Thanks. I suppose better than nothing, I suppose. I'd really like a 3 view though.
