  1. I imagine large drones will fill any serious niches it could have had uses in
  2. I've heard them explained as butt surrogates, to keep interest once we started doing it face to face.
  3. So not only did they strap a million machine guns to IS-7, they also wanted them to be fired by robots?
  4. More proof that engineering is the best subject ever and all other subjects should endeavour to be more like engineering
  5. I'm not certain that that spike launcher fires backwards all the time - it has the same curved dish that all other spike platforms have, but it's facing forwards - if the missiles go straight backwards then that antennae wouldn't be able to communicate with them. Maybe the missiles ark round to the front?
  6. Recline the driver and squash the hull, move all the ammo into a bustle mounted autoloader (and so drop the turret basket to the floor), voila. Shorter than T-64, and if you're sensible with the autoloader design it's safer too
  7. So, the amazon has a flow of 2.09E5m3s-1 [1]. Global water usage, with 176 litres per person, will hit 1.23E12L assuming 7bn people, so that's 5.89E3 seconds worth - about 1.6 hours, if we could capture the entire flow.

  8. anything interesting posted online will be reposted The roided up XM150 (with like double the chamber pressure and a longer barrel) ought to have been interesting in that regard
  9. Peak stress will occur lower than that - you just need the point through which the force acts to be in line with the swingarm (and for a trailing arm, this point is well above the axle). Once you're hitting at the axle level then some of the force will try and flip the arm round to a trailing position, which would be exciting.
  10. That sounds incredibly advanced compared to when the west first twigged onto the scientific method of trial and error
  11. Back in the 60's the brits thought DU would be cheaper in L15 than the tungsten alloy, because apparently the alloy they used was quite hard to make properly
  12. If you just necked out current rounds then there shouldn't be any difference in magazine volume, since the case head would be the same
  13. Er, sorta. The carnot cycle assumes constant volume heat addition (so it'll underestimate the work done in a constant pressure system, since the pressure is held up for more of the shot travel), and the formula for maximum efficiency of an idealised diesel engine (or any heat engine with constant pressure heat addition) is not as neat as carnot (walter should totally add this to his sig on the WoT forums) Gamma is the ratio of specific heats, and alpha is the ratio of volumes before and after heat addition. The formula for PdV work for an actual gun is going to be a hell of a lot more complicated, because nothing is constant, but I can ignore messy situations like that till next year in my course.
