    Hello everyone,

    I am going to design a I whale under water vehicle, so in this regard can anyone suggest what size ballast tank and thrusters I can provide or any manufacturing company so that I can approach.

    Whale size Length 3m
    breadth 0.8m

    Best regards

    In my opinion, the best is waterjet. This prevents rotation with respect to the longitudinal axis produced by a conventional propeller. Two coaxial propellers counter-rotating could also be a solution.
    The ballast, if you need to put some, would be imprudent to define it with the data you have provided us.

    use the thrusters/propulsion units that divers use.

    Probably has the same problem since, after all, it is a conventional propeller but with a nozzle.

    Perhaps. But divers don't like rotation either. (spinney divers can be a challenge)
    He may need two for a 3m 'whale' so that could offset torsion/rotation.
    Or, if he had 4, (2 each end) they could be used for steering/attitude control

    Do not leave us with the doubt. Has this discussion helped you to clarify/decide something?

    I am looking at the links provided and i got some information so basing on that I am moving forward. I am still confused whether to go with jet propulsion or not.

    Do not hesitate for a minute, I have experience in the subject. Select jet propulsion.
