Pratt & Whitney Canada's Boeing 747SP engine testbed, spotted yesterday visiting the Southern California Logistics Airport in Victorville (formerly George AFB, until 1992).

Model of Boeing 747 "ant-eater" or "droop nose" design finalist

Another significant finalist was the "ant-eater." So called because it appeared to have a droop-snout, the ant-eater was important because it promoted the concept of a wide single deck, as well as the idea of placing the flight deck on a different level than the main passenger accommodation The design allowed freight to be loaded directly in the main deck without having to swing the nose out of the way. The same basic concept was used 30 years later by Airbus for the A300-600T Beluga transport.

The clearest shot I've found yet of the 747 tanker's boom-operator window.

Boeing 747 modified to act as a tow-plane for the space shuttle Approach and Landing Tests.

Was there any attempt to put jet engines on Enterprise for these tests? Something similar to what was done with the Buran OK-GLI?
This post from the "US Space Shuttle Projects" thread covers the only report on similar ideas that I've been able to find.

In view of the material already presented in the forum this topic will surely motivate enough crossposting but I believe that the topic deserves to take their own place.

-A 90's proposal of GE for a Super-AWACS. A wind tunnel model existed but I have not gotten pictures of the same one.

I think many of us don't know those Boeing-747 Hydrogen fuel shapes.

This from Flight International, 4 November 1978, p. 1642: "Welch admits that 747SP sales have been disappointing, but he describes the variant as "a firm member of the family." Six more SPs out of 29
ordered by seven customers remain to be delivered, and TWA has just ordered three. In presenting the 747 Boeing emphasises that the range of the 20OB is almost as good as that of the SP (could it be the stretched SP that SP customers are now asking for?)."


Does anyone know what this author is talking about? I've never heard of a stretched 747SP, and it's very counter-intuitive.

It reads like 747SP customers had been asking for a stretched version to carry more passengers; since the 747-200 had almost the same range as the 747SP, it filled that need.

Greetings All -

A recent donation to the Museum included a box full of various commercial aircraft proposal brochures that came from the United Air Lines library. They were being thrown away at the time the donor was there visiting for research and thankfully he was able to save them. I'll start off with material from various Boeing 747 proposals and the first being a March, 1968 "Model 747-3 Three Engine Aircraft for U.S. Domestic Service". Clearly written as a study and reaching out to the airlines for their input, the objectives stated on the first page are:

"We are studying, The Boeing 747-3, a 3 engine companion to the 747

The objective is to determine characteristics of an aircraft having:

- Common JT9D Engines
- Common System
- Common Interiors, Cargo and Baggage
- Common Maintenance, Training and Spares which potentially can provide attendant cost reduction and profit potential"

Enjoy the Day! Mark

Interesting. I really should read that 747 book on the shelf :)

Very interesting, Mark. I've seen a couple of those pages in other books on the 747, but not with the comparison overlay. It's clear that this was considered at least twice: once as the 747-3, and then again as the 747-300 (a label that was later reused with the SUD). I'll be very interested in seeing what else you find. Thank you!

I probably should have posted this first to stay in chronological order, oh well. Date October 1965, this design iteration has been posted elsewhere in the thread but I'll share some other info to go with it. Note in the wind tunnel images there is a 3 engine version (with an unusual location for the wing mounted engines) along with the 4 engine version noted in the rest of the proposal brochure.

Enjoy the Day! Mark

I'm sorry I missed these when they first came out. They are very interesting, especially the ducting they were going to use on the tail engine.

I'd understood that the 747SP was primarily a strategic move to block DC-10-30 and especially the L1011-500 purchases by 747 operators so it might not have needed to show a respectable ROI to be considered a success. Even if Boeing lost money on it, it probably was a significant factor in Lockheed's exit from the market and dimmed Douglas' prospects.

The Enterprise TSTO thread at https://www.secretprojects.co.uk/forum/index.php/topic,23384 features a carrier aircraft incorporating the wings and landing gear from a Boeing 747 as outlined in outlined in the AIAA Paper 79-0879 named "Utility of High Bypass Turbofans for a Two-Stage Transport" by Len Cormier.

Hi,

in Le Fana 2/2019,there is an article about Boeing-747 and its development,they
mention that there was a LX-HLS Program,what was it ?.

Sounds like a typo for the CX-HLS program.

A typo is still a typo no matter how many times it appears.
A mistake is still a mistake no matter how many times it appears.

A quick search for "LX-HLS" yields 0 relevant search results, so a typo is likely.

hesham, did you even try to translate those snippets ?
In the last one, it is said, that Boeing under the program, which here is called
(erroneously ?) LX-HLS already had aquired 315 ha of properties for production
facilities. Hardly believable, that they did so for a programme, that isn't even
known today ... ::)

I really remember seeing that same big plane on the Flightglobal archive before, but I never saw the picture of what the plane looks like on the inside. I think it looks to be at least 16 abreast to as much as 20 abreast. So do you have any idea what that plane is called? If not, maybe you could give it your own name.
(UPDATE) I think that plane could actually be the biggest proposed NLA that was said to be 280 feet long, have a 290 foot wingspan, seating for at least 800 passengers and a MTOW of 1.7 million pounds.
(UPDATE #2) That plane is actually an artist's concept of what British Airways' superjumbo would have looked like, and it also has 3 decks, but might have room for 4 or even 5 decks due to the height of the plane's fuselage compared to the much smaller plane in the foreground
