SE Aeronautics announced a new widebody aircraft, the SE200, that promises 70 percent lower fuel consumption and the ability to lower CO2 by 80 percent with a light tri-wing design and short take-off and landing capabilities for long flights, the company said in a March 17 press release. 

"Our innovative technology and new aircraft design will lower fuel consumption by 70 percent and lower CO2 emissions by 80 percent as measured by per seat kilometer,” Lloyd Weaver, chief engineer of SE Aeronautics, said in a press statement. “The innovative design is a more efficient, light tri-wing configuration that greatly improves lift over drag, resulting in short take-off and landing (STOL) capabilities and extremely long flights. The construction is all-composite, molded in one tough, safer piece. We also incorporated super thin, long wings and complete streamlining from the nose to the tail. We did it all.”

The aircraft was also designed with COVID-19 and other airborne diseases in mind. The aircraft has a “once-through” air feed ventilation system to ensure that air never recirculates in the cabin, according to the release. 

The SE200 will carry up to 264 passengers and have a range of 10,560 miles, according to the release. The fuselage will feature one solid-molded piece, and the fuel will be stored in sealing bladders on top of the fuselage. 

"This aircraft will be the most practical, profitable and permanent solution to the grossly underperforming airliner technology of today,” Tyler Mathews, CEO of SE Aeronautics, said in a press statement. “Our manufacturing efficiency will allow us to produce our aircraft in significantly less time than the current traditional method. But the jewel in the crown is really our ability to get that fuel consumption rate down by 70 percent. We are going to revolutionize the industry.”

    Sounds awesome! Is it quieter also?

    I’m not a pilot. Heck I’m not even involved in the aviation industry
    other than occasional online reading. But, did a lot of research go into
    this article?

    I used to sail a small boat with two sails and I really have to wonder about the air flow over those three sets of wings.

    Also, I did just a bit of research, and I think it would be exceptional for a
    dietician–Tyler Mathews–Co-founder and CEO–apparently with experience at a
    company that sells boxes of organic food, and experience as a business
    development manager at a wedding venue (called Mathew Manor which is I would
    guess not coincidentally co-owned by a Harold Mathews probably the same Harold Mathews as the SE
    Aeronautics VP Sales & Marketing as one of the phone numbers on the
    SE Aeronautics website ties back to Mathew Manor) would be able to pull
    this off with a Co-founder who appears to be a mechanical and chemical
    engineer with experience in waste water treatment systems for family
    homes up to business parks, and experience in biomass energy, and no
    aerospace engineering experience that I could quickly find.

    I couldn’t find any related business listings on the Alabama Secretary of State website searching on the company and co-founders names, though I suppose they might have incorporated in another state.

    If they have a viable concept, then it would seem a significant story
    would be how a team of that background managed to develop or obtain the intellectual property
    for such a game changing concept that blows away anything I’ve ever seen planned from
    Boeing and Airbus and however many aerospace engineers they have.

    The proposed design for the SE200 is interesting, but with such high aspect wings, what speed would the aircraft be capable of…. gliders have such wings (but only one!) and are very efficient but also very slow…? If for example the plane could fly at 200 mph (?) it would take some 3 times as long on a long flught… crossing the USA would take sone 15 hours or so…who would want that, just to cross the country? And, it seems to me that the use of such long, thin wings would make the plane somewhat “bouncy”, much more than current aircraft, even in very light turbulence, which on a long flight would be pretty uncomfortable. On the plus side, though, I’d think that stall speed (and thus takeoff/landing speed) would be somewhat less than “normal” jet aircraft. I should also think that due to the extra long wings, you’d want to have high-mounted wings, to reduce the likelihood of the wingtips striking the ground in crosswind takeoff or landings. It would also make the aircrft more stable than low or mid-mounted wing(s). Me, I’d think about putting skids on the wingtips… unless you simply put in more dihedral than usual.

    If all that’s OK, though, one might consider bringing back the (helium filled) zeppelin, but constructed with more modern, lighter & stronger materiels, which might be as efficient or better…? Who knows, there might even be a way to make the use of hydrogen safe, which would be even better, since it’s lighter than helium, not to mention easier to source! An additional benefit of bringing back airships would be the incentive to fly simply as tourists, since the view from an airship would be fantastic, as the cabin/gondola would have “picture windows” to see out of, giving an incredible view of the ground, unlike flying in a modern jet, where only the person in the window seat could really see much of anything (and not much of that, either) outside. Flying in an airship would be much more comfortable, if slow, but who cares? The travel industry has made going by sea from one port to another worldwide nearly a “must do” for those who can afford it, why not the same for travel by air? Imagine flying over the antarctic by airship, having lunch looking at ice, mountains, volcanoes, penguins and whales (in the right season), all at a very leisurely rate. Or the deserts (such as over the Serengeti, during the annual migration, or the pyramids… or the jungles of South America, or wherever you want to see, comfortably- not much faster than a regular train!

    Of course due to the incredible number of passengers flying nowadays, there wouldn’t be nearly enough room- in the air or on the ground (airship hangars are BIG!)- for airships to completely replace jet airliners, even if you wanted to, so building new zeppelins would only be a partial solution at best, but then again looks like a 3 wing jet would take up quite a bit of room, as well. Add to that the coming fleet of autopiloted drones, and looks like the friendly skies will be even MORE crowded! Oh, what to do???
