    Nice, I like it. Reminds me of the seaquest series.
    Say, would it be viable to consider a waterjet system with ducts up front?
    Also will it have a configurable pressure safe payload bay? I guess it would be trouble to design one.

    Thank you haru,
    It's only four four feet long.

    All of this is effect is so negligible, its really unimportant unless you are planning on racing submarines!.
    It all been tested before. Im building a replica of the uss skipjack and have performed model tests- let me assure you that specific shape and design is about a good as its gonna get. look up the experimental design of the albacore class sub..blimp shaped is the most optimal...it never used planes only static submersion.

    There's always more to just about everything than that, which meets the eye. And innovation comes from the most unlikely places. Thanks god they didn't shut down the patent office in 1899.

    Of course it was an urban legend, but it's message is applicable here.

    sub design

    asleep helmsman- i agree with you...dont get me wrong- designs can always be tweaked..and modifications made. but the learning curve now is very slow. the advances in sub designs were exponentially fast and are now slowed as far as hull shape...but..i say if your gonna do something- go all the way...may i ask what material are you building in?..have you decided to try a sub design to build?..i might be able to help you there. in any case...maybe you will find a superior design to the albacore? ...i hope so...

    - i like the elegance of the skipjack and scorpion class myself as a preference....tell me more about your design ideas???...systems ballast etc??? please.

    best thing to do asleep helmsman is to build working scale models and use them in a fast stream somewhere near you..it really works like a test tank and youll get a feel for the design...:)

    Already got it picked out. I'm gonna do a lot of testing, before this journey ends.

    Thanks for the advice.

    The more I get the better off I'll be.

    AH, that hullform is very eye-pleasing, but I fail to see hydrodynamic, structural or constructive advantages over a more conventional torpedo-like form. What are the practical considerations that had led you to this design? Is it due to a particular form of the payload it will carry?

    You are correct. The goal is to make it as small as possible; this one is only 1.2 meters long.
    Many of the components lend themselves to more rectangular spaces.

    Thank you for the compliment.

    You’re seeing it at an angle 25 degrees or so, it’s actually sleeker than it looks. It has 8 to 1 depth, and 4 to 1 beam.

    Since I don't think the uuv will need to be that speedy, a gliding form might offer higher energy savings. Also requirements for subs and uuv are different. So it's fine to play around with forms.

    Btw.how do you plan to put in the instruments? (sectional, top covers etc.)

    I would love to tell more but I am very soon approaching the point where I need to stop sharing any info.

    I will keep you guys informed as much as posible.

    That's alright.

    Btw. have you checked the iBotics Stingray Project?

    It's interesting that they use top intakes only.

    That is amazingly similar to mine I even named it String Ray for the same reason.

    Thanks for the link.

    Huh? I thought you checked all the competitions. :D

    In that case check this old bionic Manta.
    It has an operational time of 24 hours. This seems a lot, but then I dunno under which condition that was exactly taken.

    Thanks again, they did some serious resarch and developement on that Ray.

    I would think it is expensive and not as utilitarian as a "truck" as might be needed.
