  1. I know that it wasn't in danger of rolling over every time it looked sideways, but did have issues with smoothness over undulating terrain and had a more severe side-slope limit. Strykers always seemed top heavy to me, and this just seems to make the problem a lot worse than the alternative 30mm options.
  2. Are they *trying* to raise the center of gravity to somewhere approximating lunar orbit? This looks to be taller than the MGS mount and we all know the amazing stability that vehicle had.

    Tank Layout

    I got to thinking on the merits of the actual double-V (and not the compound V that I was thinking was double-V whoops) - and since the idea seems to be to minimize the amount of area that has to be reinforced (only the trough, and even it is supposed to be slightly concave and open at the ends to vent blast forwards/back) would something like a triple-V not be better? Put third V where the trough is to make two smaller troughs, these will be more concentrated and have to be more heavily reinforced but would not heavily reinforcing those two very small troughs be similar in weight to reinforcing the single large trough while taking up less interior space?

    Hmm, that weight penalty for reinforcing the duct seems to be a disadvantage, I wonder if it is really worth it vs raising the vehicle.

    I stand entirely corrected, and yet this design baffles me. That central trough is going to act as a stress concentration for the blast wave.

    I am not sure why you would think that 3 or 6 would be a double-V hull. Mirroring that design to produce a full hull would result in an inverted trough running down the middle of the vehicle, a great weakness. 5 is the best, and a true double-V.
  7. From my memory, T__A's comments on the IS-3 ring true. They did have serious welding issues, the mechanical systems tended to overheat, and some of the crew positions were ergonomically unacceptable. This is not so much due to any major weight gain, but was rather due to a number of design flaws caused by the extreme haste in which IS-3 was developed and put into production (under a year from the start of development to production starting).
  8. Some of these Ukrainian proposals really seem to be throwing every envelope sketch at the wall and trying to see what sticks. As far as I can tell, that has been the origin of most Ukrainian offers since the 90s.

    The Leopard 2 Thread

    I am not sure how it is done for Leopard 2 components, but I have seen entire cast or welded assemblies heated up and quenched at once in appropriately massive facilities. This image of a Panzer 68 hull being Quenched at Thun always comes to mind. Welding plates post heat-treatment is very difficult without making the zone around the weld weak. It is usually preferred in metallurgy to weld before heat treatment and then do it all together.

    The Leopard 2 Thread

    Different crystal phases of the steel, essentially the grade "P" armor is welded while still hot, the other grades are welded at much cooler temperatures. Likely implies that the grade P material is welded post-heat-treatment, while the grade Q and R metal is welded pre-heat-treatment. (This is not necessarily the case, but would be the most likely reason for welding at different phases).

    AFV Engines

    While only tangentially related, I find it interesting that the M1 apparently has issues with the terrain of the Golan Heights, not because that terrain is easy (it is very nasty terrain) - but rather because the US extensively has tested the Abrams on the Yakima Training Center grounds which has lots of similar basalt. I wonder if the YTC gives the Abrams headaches.

    General AFV Thread

    What I find most interesting is this seems to confirm that the Type 90, at least for the hull, doesn't have a 60 degree frontal arc of protection. Odd decision, really.

    General AFV Thread

    Now, I am pretty sure this is the right thread - but @Waffentrager has managed to put this diagram of the various material sections of the Type 90 together. The blanked-out APFSDS in the RED description is JM-33, which (as I am sure most everyone here knows) is their variant of the DM-33.

    It's a HRG. Hemispherical Resonator Gyroscope - it would be a major accomplishment of Russian industry if they have actually put these into mass production. Only two firms on the planet so far make them. (Also, first actual post of a longtime lurker!)
