    TIL how to make a high torque CVT, @Xoon
  2. Lord_James
    I remember discussing about this thing in the WT forums: IIRC, this thing is a training vehicle for Type 74 crews.

    I read something about a “PT-76M” for the Russian marines, with ‘enhanced displacement’ but wasn’t adopted, on Wiki, but take that with a cup of salt.

    I don’t know where to ask this, but I have a question: https://apps.dtic.mil/dtic/tr/fulltext/u2/609554.pdf “Development of a structural uranium alloy” What advantages would uranium alloys have over steel or aluminum? It’s rarer, much heavier without a significant increase in strength, difficult to work with, and I can’t think of anything (off the top of my head) that a high density material would perform better than common structural materials, except maybe the mass dampener in Taipei 101. PS. The article refers to Niobium as ‘Columbium’, Cb.

    When did Soviet tanks get independent commander’s thermal sights? I think I remember it was in the 90s, with the T-80U and T-90, but I have some doubts.

    Is this really an insult, though? Half of America calls Trump a retard anyway; I don’t think some Middle East shithole’s opinion makes a big difference.

    Lets hope nukes don’t start flying.

    Not to mention, if Iran does it again, it will be a million times harder to play it off as “a mistake”. I hope it doesn’t come to war, because Iran will get absolutely rofl stomped, and also I don’t think many people would want another ISIS popping up in a country with possible nuclear weapons capability.

    Are Mg alloys AMX602 or ZAXE 1711 available for use? Or maybe WE43B and Elecktron 21 (EV31A)? I'm thinking about using some Mg to lighten my vehicle. AMX + ZAXE: https://apps.dtic.mil/dtic/tr/fulltext/u2/a562406.pdf WE43: https://apps.dtic.mil/dtic/tr/fulltext/u2/a562514.pdf Elektron 21 + WE43: https://apps.dtic.mil/dtic/tr/fulltext/u2/a597768.pdf

    https://apps.dtic.mil/dtic/tr/fulltext/u2/a168578.pdf ferro-aluminide alloys. The best are alloys with niobium, chromium, and tantalum - followed by titanium, copper, and the base line FeAl (not in order). Surprisingly, FeAl + silicon alloys perform (nearly 3 times) better at 600 C than at room temp.

    Needs more shitty ERA.

    Isn't foam armor expensive, with a high variability in effectiveness due to random cavity formation?
  15. Lord_James
    my first thought was it's based on the SIBMAS, but yeah, Ratel / G6 derivative could also be true. I do wonder: was this developed with assistance from a foreign company, or is this 100% in-house?
  16. Lord_James
    My favorite are doom speedruns: And I just discovered 0% speedruns (no upgrades, secrets, or challenge progression):

    ERA is more dangerous to surrounding infantry than a 6in ATGM like Kornet or TOW?
  18. Lord_James
    Spaced armor messed up early Tungsten Carbide ammo, and probably Cermet-cored HMG ammo, too.

    ‘Iron Fist’ is not suitable for the Stryker? A little surprised by that, as ‘Iron Fist’ doesn’t take up a lot of space (relatively).
  20. Lord_James
    The MBT-70 wasn’t in need when it was being designed? And after it died, both countries involved didn’t have to upgrade older tanks to stay competitive? It is the same scenario, just 50 years later.

    I never did respond to this, despite my vehement disagreement, but how the program is “too big to kill” is not valid: research and development programs, no matter how much of a need, or how much money and political backing they have, can fail very spectacularly. This new ‘Europanzer’ is no exception, and I have reservations that it will actually bare fruit, considering how well past international tank development programs have gone.

    https://apps.dtic.mil/dtic/tr/fulltext/u2/a139649.pdf “Fracture behavior of a uranium and a tungsten alloy in a notched component with inertial loading” Tl;dr, the rear section of a long rod can be damaged during launch, which can be solved by these simple tricks ballistic physicists don’t want you to know about: 1. Increase ‘lug root’ (the zigzag structures holding the sabot to the rod) radius. 2. Move the rod farther forward, relative to the sabot, so less of the rod is behind the sabot. 3. Reduce the stiffness of the rod, especially the parts behind the sabot.

    Because (as far as I know) we don’t have a material science section of this forum, I’ll link this here: https://apps.dtic.mil/dtic/tr/fulltext/u2/a405973.pdf “Depleted Uranium: a case study of good and evil” tl;dr, DU is no more harmful than other heavy metals used by armies across the world, like tungsten and lead. The fears and concerns proposed by people regarding DU’s toxicity are caused by misunderstandings and a lack of critical thinking / fact checking. In other words: water is wet.

    Thank you - I always value when you explain something, as it’s usually descriptive, yet understandable to my feeble mind For the German 105 smooth: I knew it was mounted on the Leo 2K and other prototypes before the actual Leo 2, but any specifics were always missing, or conjecture. I didn’t know about the “roided up L7” though; does sound like a good idea, though it is still rifled. I may have misread about the Brit 110, I remembered it as a rebore’d L7 to remove the rifling so it could fire better ammo, while still fitting in current L7 armed vehicles. I guess I should have known that was too good an idea for the post WWII British MoD; not the worst idea those wistful crones have forced upon their army, but still disappointing. Anyway, thank you again, Colli, and let’s get back to Soviet tanks and their transversely mounted engines!

    I keep hearing talk of this 105mm smoothbore (and the British 110mm smoothbore), but I have never seen anything on these weapons.
