The idea was to maintain laminar flow. To do that they needed short chord - so to keep the aspect ratio from getting silly while providing enough wing, they went for a biplane.

"The last patent is totally lunatic "
Well, this principal was used for the Agusta A 119 in four engined form,
a contender for NBMR 4 from 1961, although I could imagine, that
flight control in a hover would be easier to achive with 4 lift vectors,
instead of only two.

pometablava said:Jemiba,
I was talking about that Boeing 1 and Boeing 2 drawings...are they real?
Actually... yes. The design is slightly different in details, but Boeing did put together such a beast. I don't have the data hear in front of me, but it was meant as a VTOL heavy lifter... and two of the intended payloads were the first and second stages of the Model 813 hypersonic bomber that I describe in my "Preview."
Sometimes the wacky patents aren't complete nonsense.

And this one http://www.secretprojects.co.uk/forum/index.php/topic,2420.msg21253.html#msg21253was probably an ICBM launcher... , or an Artic carrier.

Um, same as this http://www.secretprojects.co.uk/forum/index.php/topic,1522.0.html . The comments on that post are still valid, I think...

A natural gas transport. Boeing designed a number of Really Big Airplanes for transporting natural gas back in the '70's.

Note... this was at least a *somewhat* serious design. I've got drawings of it somewhere. I don't think that it had a Model number, though.

Sentinel Chicken
American 71 Heavy, contact departure 126.47
That second one is the famed "Hunchback of Mulkiteo" design when Boeing was looking for ways to increase the capacity of the 767 design (ultimately moving ahead with the 777 and the 767-400 designs). The nickname came from a Seattle surburb. From what I recall, airlines polled were very lukewarm at best with the idea of a hunchbacked 767......

Hesham, NOT Boeing AND North American, BUT Boeing North American, Inc.
Boeing North American (BNA), Inc. acquired this Seal Beach facility in late 1996 from North American Rockwell. The multi-building facility was used by Rockwell to build large defense and space hardware including Apollo launch vehicle stages. Boeing has two major divisions: commercial space (primarily airplanes), and defense and space. This Seal Beach facility was acquired to enhance the capabilities of the defense and space division.

That last one appears to be the aborted 7J7 program which would have had a twin aisle jetliner powered by GE UDF engines. I believe the "J" came from plans to have significant participation by the Japanese aerospace industry.

According to published accounts Boeing's ATF proposal concentrated heavily on their weapons bay, so its quite possible the YF-22 arrangement was their "baby".

Boeing Heliwing
Boeing Heliwing vehicle of the early 1990s. This vehicle had a 1450-lb maximum takeoff weight (MTOW) with a 200-lb payload, 5-hour endurance and 180 kts maximum speed and used twin rotors powered by a single 240 SHP turbine engine/
Boeing's Heliwing VTOL UAV took off and landed vertically from a tail-sitting position, but transitioned from hover into fixed-wing forward flight by nosing over. One demonstrator was built, which crashed while attempting its first retransition from forward flight to landing hover on its sixth flight on 13 Jun 95.
