An all-new Boeing 727-300 concept for modern times

An all-new Boeing 727-300 concept for modern times

As we all know, only two variants of the Boeing 727 were produced. The -200 was (by far) the most successful version of this aircraft with over 1245 units sold. Then of course there was the -100, which was the smaller variant to compete against similar-sized aircraft from other manufactures. It wasn’t as popular as the -200, but it sold well (407 total). But what about the Boeing 727-300? Wasn’t that supposed to be a thing as well?

First of all, what ever happened to the original Boeing 727-300 concept?

The Boeing 727-300 was an actual design proposal formulated way back in 1972 in conjunction with United Airlines and Indian Airlines. The intention to increase the size of the -200 model to accommodate up to 180 seats, and with the explosion of air travel early 1970s, this came very close to being pushed through development and into production. However, neither airline committed to ordering the aircraft, and the project was canceled in 1976.

And believe it or not, there was actually a -400 model proposed as well. Ultimately, that design proposal evolved into the 757 concept, thus driving a stake right through the heart of the 727 program.

Coming up with my own concept for what the 727 might look like if it were produced today

Since the 727-300 was never produced, I figured it would be fun to take a crack at designing what a next-generation version of the 727 would look like. To be honest, I didn’t know what to call it at first, but I figured that giving it a -300 designation made the most sense since that’s where the legacy of this aircraft ended back in 1984.

Those of you who have been following me know that this isn’t my first rodeo. I’ve already made a post about the Boeing 757 replacement. I even made a 797 concept based on the 787, and since I haven’t received any credible death threats yet, I assume that means that I’m good to go to start hacking up another perfectly good airplane.

By the way, here is the full video I produced which shows exactly how I created this 3d model. If you aren’t a fan of reading long articles, I’d recommend watching this instead:

And just a quick disclaimer before proceeding: I’m not an engineer, but I do have a really annoying knack for not being able to leave perfectly good things alone.

Combine that with some decent 3d modeling and Photoshop skills, and my sincerest apologies to Boeing for what I’m about to do to their beloved 727.

Step 1: Evaluating the current design

Taking a look at the existing 727, and you can see that it was a beautifully designed airplane that was very much ahead of its time.

Can you believe that something this sleek and edgy was designed in the 1950’s? BTW, huge props to my cat for volunteering to be a hand model for this shot.

Think about what cars looked like from that era. This is nothing like what Studebaker and Edsel were producing at that time. I’m not saying Boeing engineers were into mind-altering substances or anything but…whatever it was they were consuming, that stuff must have been good.

From the sharp rake of the wings to the blended engine into the vertical stabilizer, it’s really hard for me to think of ways in which this design could be modified to bring it up to modern standards.

This is gonna be a challenge…

Step 2: Designing an all-new wing

The first thing to tackle in this Boeing 727 redesign process is the wings. As I mentioned earlier, I very much like the swept-back look of the wings already. However, there ain’t no way I’m going to miss an opportunity to rearrange and deform some polygons.

I decided to go with a longer wingspan with more surface area…mainly because of the more powerful engines I’ll be adding in just a moment.

Bigger wings may or may not make a difference in efficiency and performance with this existing airframe, but its content for this article, and besides:

It’s fun to think of all the aerospace engineers holding their head in absolute horror as they’re watching this. Its okay though, because I’d be doing the same to them if they tried to put together a decent airline review.

Unless (of course) they actually hold their heads in absolute horror as they read MY stupid airline reviews.

Anyway, back to the wing redesign. I decided to go with a split-scimitar winglet, as opposed to a seamless blended design like I did on my 757-8 concept.

My hope is that you’ll find this so incredibly good-looking that it takes your mind off of my horribly-botched pronunciation of “scimitar” in the video I posted above.

Step 3: Eliminating the center engine (*gasp*)

Next up in this Boeing 727 modernization is the tail section. Now, this is where things start getting serious, and some might say that this is where this becomes more of a hack job than a redesign.

Why? Well, with engine technology being what it is these days, I have reason to assume that the center engine wouldn’t be necessary on a modern 727. Two engines ought to do the job just fine.

I know! That center engine was one of the elements which made a 727 a 727, and by removing it, is this really a 727 anymore? That’s a question that I don’t have a clear answer for, so I’m going to press on and ignore it.

Pardon me while I do the unthinkable by deleting that iconic #2 engine!

Of course this means completely redesigning the vertical stabilizer as well. Which also means reshaping the tail cone. Which likely also means that at least one of you is yelling obscenities at me as I do this. It’s ok. I totally deserve it.

Other than how it attaches to the fuselage, I’m not going to do much to the existing shape of the vertical stabilizer.

I quite like how the original design looked. It was just as sleek as the wings, and there’s no reason to make you hate me more than you already do.

I also figured it was worth reshaping the horizontal stabilizer a bit. I’m making it longer, for no reason other than just trying to make it fit the shape of the redesigned vertical stabilizer better.

On a side note, why aren’t winglets on horizontal stabilizers a thing yet?

Step 4: All-new engines

How you doing so far? Are you still with me? I guess if you managed to get though my elimination of the #2 engine in the last section, the rest of this is gonna be cake.

The last big element to tackle on this Boeing 727 redesign is (are?) the engines. Truthfully, there’s so much I could have done with this.

From eliminating the side-mounted engines altogether and enlarging the center one, to adding multiple engines to each side, the possibilities were interesting.

Boeing 727-300 engines
Because I’m trying to make this as realistic as possible, I’m not going to do anything crazy with the side mounted engines. They will remain, although slightly larger and much more powerful than the existing Pratt & Whitney JT8D’s.

Again, I’m not an engineer, so I can’t tell you exactly how power much these new engines will produce. Let’s just say:

  • 10,000hp
  • 12,000 lb/ft of torque
  • 1 terabyte of ram (I dunno…)

Finally, as far as the other little details go, there’s really nothing else worth mentioning. I’m not going to do anything with the nose cone or landing gear, primarily because I feel as if I’ve done too much already with the elimination of the #2 engine and it’s borderline not even a 727 anymore.

Introducing the all-new 727-300!

In the video you saw above, I never went as far as calling this a -300. However, shortly after publishing it, I had a moment of clarity and decided that it was probably the most logical name for it.

Well, here it is. I formally present to you the Boeing 727-300!

So what do you think? Is this what you would imagine a redesigned and modernized 727 to look like?
Boeing 727-300 tail section
Yeah, it’s very 717 / MD-80 like from certain angles. Maybe that means I should add a 3rd engine to any 717 / MD-80 concept I create?

The front end is still very much a 727 though. See? This wasn’t a total hack job.

By the way, that notch in the lower section of the vertical stabilizer was a last-minute addition. It’s easy to make big changes when you aren’t an engineer!

Quite possibly the best view of all. That’s a good lookin’ bird!

And just so you know, I do realize that Boeing would never put the 727 (or anything based on the original design) back into production. It’s just a fun idea to kick around while I wait for the pandemic to be over so I can return to the skies.

And besides – you have to admit that this was slightly better than doing silly like an in-depth nail clipper review. I can’t promise that it won’t happen though…
