      From: adam.w.krajewski@gmail.com              "So all of this is left away from the expected battle zone, and it's armed       simply for self-defense so the actual battleship has something to come back       to, right?"       Ok, so, to start with, the cylindrical and octagonal parts are together with       the brick, nothing is left behind, I should make that clear at the beginning.       So, warship is: engine, reactor, weapon ring, crew and cargo, coilguns,       frontal antennae array with        spinal mount. They are all parts of one vehicle. The tugship is a completely       diferrent story.        As for particle beams, I honestly don't know why I put them here, maybe the       justification for them could be the ability to give some fast punch at long       end of engagements distances, at which normally the missiles are used? Their       "ammo" is quite light,        and their time to target is short... What do you think?        As for armor for ferry phase, the ship as a whole is attached behind the tug       with its own shield, so the need for warship to carry it fades away. Although,       I think I will put something like this on front.       For the crew: In interstellar trip they are in hibernation, when they arrive       to target they wake up and stay awake for time of mission, if the ship carries       payload of troops, the crew is awake as normally, but the troops are sleeping       until there is a        need to drop them into battle. The size of the ship makes me think, what would       be the size of crew, it's bigger than Nimitz class aircraft carriers, that       have a few thousand people on board IIRC.        For the steer and portside - I forgot that it should be "board" not "side",       and that in English it's "star" board, not "steer" like in my country.        Fighter launcher you say... Hm, for now the ships hangar bays have quite a lot       of places that can deploy the smaller crafts, but, that could be an option...       Especially when the spinal mount connects to the hangar, where the       compulsators, recoil systems        for coilgun would be mounted. Also, fighters in space?:p        The barrels are quite "fat" already, like 1 meter, for a 10 kg projectile that       will be 50mm wide that's quite a lot I think (I used that value today when       calculating lenght, magnetic field strenght etc using Mr Campbell's equations       found on Atomic        Rockets, I made some mistakes though and results are weird).       On power storage, technomagic supercapacitors you say... Made from silica       based shells of intelligent insectoids who are the only lifeform that has a       special silicen nano structure in it? Sounds nice :D The compulsators sound       good too, but they would        need some armor, violently rupturing wheel at thousands of rpm could do big       damage I think.        Fast googling did not get me power density, but gonna search for that later.        And again about something rotating, today I started thinking about a big       technological challenge, mounting 26 m wide turrets in a way that will keep       them from falling out of turret rings. The naval battleships had the turrets       just lying on rollers, if        the ship would turn sideways they would fall off... And we need them to not       fall off at a few Gs...        Anyway, big thank you for your effort here, without you and others help making       all these projects wouldn't be possible!              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
