First of all - hi Gregory :)

And here are some realy unusual transport concepts:

1. Boeing natural laminar flow study from 1977
2. Boeing study for fast airliner just before Sonic Cruiser was born

Sources: (1) not known (2) Aerospace projects review V4N5,
That transonic airliner design sounds familiar- do you know the year it was worked on? I seem to recall that just prior to the Sonic Cruiser launch Boeing was working on an in-house study called "Yellowstone" that if I remember correctly was for a trans-Pacific transonic aircraft.

In the late 1990s if you went to Boeing's Everett facility, before the tour started they had you sit in a theater for a brief introductory movie and back then, visitors also filled out surveys that were basically asking if you'd pay more to fly somewhere faster.

The pic of the 767 marked model of the transonic concept appeared in Air Enthusiast in 1971...it was a serious contender, the oil crisis of 1973 put paid to the high-speed concepts and the twin-jet design took the honours.

"Yellowstone" is the code name for a wide ranging family of studies, the 787 is one result as are the aerodynamic changes to the new wing for the 747-8. It was worked in parallel with the Sonic Cruiser and much data was shared back and forth.

I'm currently at Boeing working on 787 electrical design.

Cheers, Jon

Does anyone have any details about the engines proposed for the Boeing transonic airliner studies?

I would assume that that a low bypass ratio (<2-3:1) type would have been used?

Indeed, isn't a conventional high bypass ratio (4-6:1) turbofan incompatible with transonic performance?

A Boeing project for a transport with a laminar flow wing. Seems to use
quite a lot of C-5 components ...

Hi,

The Boeing-727-257 was a project and had an engine on each
side of the fuselage above and behind the wing,Boeing-727-264C
was a project of twin engine mounted on the aft fuselage and with
speed capsules for increased mach number and Boeing-727-265
was a project of twin engine mounted at the wing.

Yes Agricola,

And there was anther two projects to Model-727,The Boeing-727-474
a four engined variant of Model-727-264C and the Boeing-727-475
a scaled-dawn of Model-720.

Hi,

Early design to the Boeing-747-3.

Hi,
Here is a pic showing the final designs considered for the B747. Among them, I find very interesting the design dubbed "Ant Eater". Any aditional 3-view of these designs, apart from the midle mounted wing proposal submitted by Hesham? I think it would deserve a whole thread the design process carried out for the mighty Jumbo, including the conections with USAF´s heavy airlifter program (CX?) .

Hi,

The Boeing studied a fan-lift VTOL system version of Model-737
which was fitted with lift jets mounted horizontally below floor
level and exhausting through swivelling nozzles.

First and third (C-wing) were extensively studied by NASA and Boeing for a very large transport aircraft configuration, trying to avoid the problems of double-deck and very large wingspan in airport handling. A later C-wing configuration was a BWB.

The optimism of early supersonic passenger flight....Pan Am and the Boeing SST 2707-200 with its large canard, double-jointed nose, and swing wing. The space age theme is my vintage style pitch. Enjoy :)

Double-deck Boeing 707

Double-deck airliners are not new. Aside from the Saunders-Roe Princess flying boat and the Breguet 763 (two craft that actually flew), Boeing proposed a double-deck version of its model 707 to accommodate extra seating.

Two pictures initially posted by Dronte on April 04, 2006 in a topic that has since been split:

A design of a mach 3 SST that swallows their own shock wave (Design original
of Flight Safe Instrument Corp. patent acquired by Boeing) (source: Popular Mechanical edition Argentinean October of 1994)

After giving it a closer look, it would seem that the Model 753 is a design evolution of Models 751-103 and -106 (see attachment).

I think it is therefore appropriate that they both should belong to the same topic.

Hi,


The Boeing Model 731 was a high-wing four jet military strategic
transport aircraft project,intended to compete Lockheed C-141,
in SOR-182 competition,and also the General Dynamics submitted
a proposal to this contest.


From the book; Warbid Tech, Lockheed C-141 Starlifter

Wow thanks! How about this angle?
Vertical stabilizer looks like 707.

Somebody did, yes, a couple of weeks ago. Where exactly escapes me at the moment, but they're definitely there.
