Nice additions, I really like the neat touch of showing the P.1101 V1 (though I expect some additional detailing on the engine would be possible if good enough photos are available).

Just got some respite from real-life issues and took the chance to finish another of my long lasting FD scale WIPs.


Boeing 747X and Boeing 747X stretch.
This was Boeing's second proposal for a new version of the 747 made inbetween the 747-400 and the 747-8. It was announced in 2000 as a plan for three different passenger models; The 747-400X, the 747X and the 747X stretch.
The 747X featured a relofted wing with extra inboard section that extended the wingspan to 69,8m, larger winglets, modified and enlarged rudder and horizontal stabilizer surfaces. Newer more powerful and fuel-efficent engines provided by either Engine Alliance (GE+P&W) or Rolls-Royce added to the increased fuel capacity would have allowed to carry up to 430 passengers to a range of 16.100/16.300km. The Stretch variant increased the fuselage length by 6,3m (to a total of 80,5) to carry 500 passengers over a range of 14.500km. Freighter versions were also planned to be offered.
Ultimately, neither the 747X and 747X Stretch managed to garner enough interest to leave the design phase, the only exception being the 747-400X, which entered service as the 747-400ER (although with only six orders from Qantas).

As a little and quick extra, the 767-400ERX:
Around the same time Boeing was working on the 747X, a new longer range version of the 767-400 was offered as well: Powered by the same engines (EA and RR) it promised a range of at least 12.000km (some 1.600 more than the standard -400ER). This as well never reached the production phase.

edit:
almost forgot, sorry for lacking of the mentioned Rolls-Royce engine choice, but I've not found any schematics or informations about how the planned trent600 would have looked. More so, there were more than one planned Trent600, the first was supposed to power the MD-11 (then BA bought Caledonian and Air Europe folded, deleting customers that asked for that powerplant), the second was being designed for the 747X. So in case I might ever find something, it would still be possible that it is not the one I'm looking for, or worse, that there is no info to tell apart the two different types.

Another unbuilt airliner from Everett: the Boeing 727-300.

During the 70's Boeing studied some more improvements for its -at the time- best selling jetliner. The first was a simple stretch that retained pretty much every feature of the standard 727-200 airframe, with the possible exception of the fitting of more powerful engines.
The second, and more interesting, surfaced in the late 70s. Featuring increased wingspan, four-wheel main landing gear, enlarged vertical and horizontal tail and, much more striking, the deletion of the central engine, turning the trijet into a twinjet by fitting high-bypass Pratt&Whitney JT10D powerplants then under developement. This particular proposal was discarded in favour of a more extensive and fuel-efficent design, which ultimately evolved into the 757-200. The P&W JT10D also entered production with the new denomination PW2000.

I love it! It's like a beefed-up MD-90/717 alternative. A hypothetical "727 MAX" featuring newer LEAP engines, winglets, and a glass cockpit with only two crew would make a great AU design.

I had read about the B727-300, but had never seen it before. Well done!
