Is the rear passenger door the advantage that Boeing engineers suggest?

Thanks for finding this lovely old image Hesham. Note the model in the foreground is almost the final design, but not quite. I have a similar picture which shows the engines have the Pratt & Whitney concentric tube silencers fitted to the exhausts. Note too how the centre-engine intake is swept back at an acute angle; quite rakish don't you think?

I recommend reading "Billion Dollar Battle" by Harold Mansfield; (c) 1965, David McKay & Company. There is a photograph of Jack Steiner and John Yeasting inside the Boeing 727 fuselage mockup holding a set of plans showing this earlier engine configuration; the outboard engine pylons have swept-back trailing edges......

I also recommend "The Boeing 727 Scrapbook" by Len & Terry Morgan; (c) 1978, Aero Publishers Inc. There is another photograph of the model in this configuration on page 26, with George Sanborn and Wellwood Beall. Earlier Boeing 727 design configurations are shown by 4 models in the background; a mini Boeing 720 configuration, an overgrown Boeing 737 configuration, something like a 3-engined Caravelle and a twin engine design with engines embedded in the wing trailing edges, De Havilland DH118-style......

All best,

Terry (Caravellarella).

Uh, that wing box is rather far forward isn't it? Since we can't see the rear, I wonder if this is a box wing?

Model of Boeing 727 Model 265 located at the Boeing Archives Bellevue, Washington.

This rare proposal for the Boeing 727, Model 265, would have used the same engines of the Boeing 707s of the time. It's under-wing engine configuration became the inspiration for the Boeing 737.

Models of Boeing 727-300 located at the Boeing Archives Bellevue, Washington.

Boeing studied a final stretch, re-engine, and technology upgrade of the Boeing 727 in the early 1970s. The 727-300 called for an 18 foot stretch of the 727-200 fuselage, a modified wing, new four-wheel main undercarriage trucks, and high bypass Pratt and Whitney JT8D-217 engines. It was designed to carry 220 economy passengers over a 2,000 mile range with 10% better seat costs than the 200. It was originally pitched to Braniff and United, major 727 operators at the time with production scheduled to begin in 1975. An alternative program, the 7N7 competed with the 727-300 at the time. The 7N7 went on to become the 757 and further development of the never-built 727-300 stopped in 1975.

On a side note, any idea what the type in US Navy colors in the background of 19059.jpg was? It looks familar.

Wild guess: a contender for the COD contract (in the same vein as the DC-9 and Fokker F28)?

Also, it only has 2 turbofan engines; an advanced 727 proposal?

The model named 'Boeing IRA', seems to be a 'wide-body' version....
could this be a '767' counterpart to the '757' twin-engined 727 version?


cheers,
Robin.

Thought it might be something like that.

The 727-300 emerged as a concept in early 1974, initially with JT8D-17R engines - that is, the original fan design. By the end of the year it turned into the 727-300B, with refanned engines, wing mods, four-wheel main gears and much higher performance.

http://www.flightglobal.com/FlightPDFArchive/1974/1974%20-%202100.PDF

It was on offer to United and Boeing was so sure of it that they even let Flight do a detailed cutaway "on embargo", to be published when the -300B was launched.

And then, late in the summer, it was whacked:

Greetings All -

A recent donation to the Museum included airliner brochures to United Air Lines for various proposals. The donor happen to be at the UAL Library doing research when they were going to toss these out - thankfully he was able to save them from the dumpster.

I'll start with the 727-200 Improvements brochure dated May, 1969.

Enjoy the Day! Mark

Finally, there is a brochure (no date) for what is described as 727-300 Model D4-048 which is a wide body derivative of the 727.
