    Ya, but part of the reason for that is because the Char B1 was sucking up all of the resources that should have gone into making more modern medium designs. As for their doctrine and C&C, it was perfect for fighting WW1 all over again - built around a process of slow, deliberate, centrally-coordinated movements focused around artillery fire massing and coordination. It just wasn't up to the task of orchestrating manoeuvre warfare (and the very real dysfunction didn't help).

    Indeed. Not a good bet, as it turned out. But you can't blame them for at least hedging. The French, at least, went into WW1 adamant that it would a war of offensive manoeuvre (based on their previous experience with the Prussians), and it was for a month or two. And then it wasn't and they lost a generation of young men. If I'd been bled white and had chunks of my country rendered permanently uninhabitable because I didn't put money on the defensive being dominant in the last war...

    Let's just say that the British hedged hard against the possibility of WW1 breaking out again. I mean, look at TOG's original requirements...

    Cromwell/Comet being the most egregious example.

    If only any of their vehicles had had a turret ring worth talking about, something decent could have emerged before war's end.

    Indeed. Lots of little wheels != fast
  7. Toxn
    Exactly. Earthmovers also don't have to worry about suspension travel and such, meaning that you can pack your extra wheels in aggressively.

    Whoops, ended up quoting when I was trying to edit.

    So here's a question: is it better, without using interleaving or whatever, to have a few big road wheels or lots of little ones in terms of MMP? Here I'm going to ignore things like travel and have no spacing between the roadwheels. For a 5m track contact length, 40t vehicle with the other specs kept the same (track width 0.6m, track pitch 0.15m), you find that ground pressure rises quickly and then tails off as the size of the road wheels decreases. This rapidly leads into diminishing returns: 25 axles with 20cm roadwheels gets you an MMP of 95KPa, 50 and 10cm road wheels gets you 67, and 100 axles with 5cm road wheels gets you 48. If you restrict things further to sane territory (12-4 axles), on the other hand, you get the following: 12 axles/0.42m roadwheels: 137 KPa 11 axles/0.45m roadwheels: 143 KPa 10 axles/0.5m roadwheels: 150 KPa 9 axles/0.56m roadwheels: 159 KPa 8 axles/0.63m roadwheels: 168 KPa 7 axles/0.71m roadwheels: 180 KPa 6 axles/0.83m roadwheels: 194 KPa 5 axles/1.00m roadwheels: 213 KPa 4 axles/1.25m roadwheels: 238 KPa So in this part of the range the relationship is more or less linear. It's also clear that the easiest way to improve ground pressure, mutatis mutandis, is to pack as many wheels as possible onto a given length of track.

    I was wondering about that myself, actually. I think part of it was that they had a bunch of hulls, plans, jigs and engineers on hand who'd worked on the things. So, you know, use what you have. I think the other thing (as can be seen with the AMX 50 and Bat Chat) is that they were on a big drive to put a really powerful gun on a mobile chassis and still have it come out to less than 50mt (presumably while also being rail-transportable). So pneumatic road wheels and torsion bars must have appealed simply to keep dimensions down. Pity that, like most German wunderwaffle tech, it was all a technological dead end.
  11. Toxn
    Sadly no - I used the 1972 MMP equations and noodled around a bit with variables. From a gaming sums perspective, what they do is introduce a new term (tire deflection) which increases effective track contact area. Even a few centimetres makes a big difference here. Realistically, of course, you're right - having soft, flexible bits on road wheels seems like a recipe for issues unless the vehicle is very light to begin with (at which point MMP more or less sorts itself out).

    There's a reason we have this emoji:

    Aka the most complex way to produce a munitions schlepper.

    So, since I finally found a good document for MMP calculations: the one thing that interleaved roadwheels are amazing for is to allow you to cheat MMP calculations. The other ways being pneumatic roadwheels and long-pitch track links.

    In our time, us old salts have seen dumber things come crawling out of the muck and mire that is German tank discourse. But this one is still all kinds of stupid. It's sort of endearing, really: the inbred, brachycephalic version of an intellectual swamp creature.

    RE the WT April Fools event - tailspin is giving me serious OG WoWP vibes, which is making me very happy. The 2077 ground forces event... not so much.

    "Obstinate or unreasonable attachment to a belief, opinion, or faction; in particular, prejudice against a person or people on the basis of their membership of a particular group." So what group are you part of, that I'm unreasonably or obstinately prejudiced against you?

    So apart from the biggest theatre of the war, where the Axis lost more than two thirds of their total casualties?

    This has been dealt with already, but dude. It was literally Red Army doctrine later in the war to do successive pincer movements (as part of the revival of deep operations thinking). That's literally the entire story of the Eastern front in 1944 and 1945. You are so fucking ignorant.
  23. Toxn
    We literally know the name of the guy, as well as the fact that he a) had a patent on interleaved road wheels and b) was part of 6th Department, which functioned as a procurement office during the pre-war and early war period. Shockingly, almost every project which passed through 6th Department ended up with requirements for interleaved suspension. And the second that Kniepkamp (and later 6th Department itself) got sidelined these requirements faded away. This is one of the more obvious cases of industrial favouritism in the second world war, with engineering considerations being very much a secondary concern.

    While I'm bitching: I finally managed to get a long, straight piece of red karee (a local hardwood), split it and discovered that, for some reason, the grain runs in a spiral. This is apparently a thing with some trees. Which was a disappointment, given that I've been waiting on that particular tree to offer up a suitable limb for years now. All of which makes me think that part of the reason for the circular-section tropical longbow might be that there's no point trying to follow grain boundaries when they wrap around the damn log.

    This has basically been my experience making bows, but red oak is an exotic luxury wood.
