    The P-47 is crying in its grave that this is her legacy.

    In a pusher prop engine, do the exhaust gases reduce the efficiency of the propeller? Hotter, and therefore less dense air would probably be less ideal to propel yourself with than ambient air.

    It looks like there’s a piece of ammunition in those large tubes, that silver grey thumb tack in the second from the left. Probably not real ammo, a surrogate to make sure it’s correctly assembled?

    It’s fine, I still understood what you were saying . The Queen E’s were very good, but still suffered from the typical British engineering practice of “penny wise, pound foolish”. However, this is about her majesty’s admirals, and not their boats, so I’ll stay on topic. I believe Fisher was a more intelligent admiral that the both of them, some of his ideas having very good foresight of future events, also his 2 legacy ships, all big gun battleships and battle cruisers, even if both were not used as effectively as theorized.

    Admiral Fisher is rolling in his grave; if you’re going to cite OG British admirals (the few good ones there were), cite the best Also, I’m pretty sure Pennsylvania was the most powerful battleship in the world, with 50% more guns at only 7% smaller caliber.

    The blog and my phone don’t want to cooperate, considering “a problem repeatedly occurred” 4 times before I had read the first paragraph.

    Stealth Basics

    Lord_James replied to Toxn's topic in Aviation

    Would decoys or active countermeasures (like chaff) be counted as stealth, since they make it more difficult to gain a target? Or is stealth, in this context, not being seen in the first place?

    I feel like that acronym was planned from the start, considering they could have just as easily gone with ERAC (extended range artillery cannon).

    Not 100% sure where to ask this, but here seems most appropriate: Do turbochargers or other aerial turbines have any troubles with humidity or water/liquid vapor? I know steam turbine blades don’t do so well when the steam condenses on them, but I’m not sure if turbo blades operate at such extremes.

    Do those guns have the same propellant load as the normal L7? I would think squeezing the round down would necessitate lengthening the cartridge, which isn’t preferable to reducing the size of your tank, or necking it down significantly.

    Are we going to do a Morman JDB comp next, or are we going back to cascadia to check back on Norman? Or am I just thinking too far ahead?

    Oh, do we have bot support on this forum, too? @N-L-M, @Sturgeon, @LoooSeR

    It’s pretty bad. It tries to set up a bunch of emotional scenes but falls flat, it’s tone deaf (these are the kids of the one ghost buster who was romantically awkward… which either kills the joke, or makes this whole movie a joke), and it’s just flashy without substance. HOWEVER, I will mention that they do use some practical effects which I did like (when using the proton beam, there are practical pyrotechnics on the objects it hits), and Zuul and Vinz look pretty good imo, but doesn’t actually frighten me, while the old 1984 demon dogs will still give me anxiety.

    Since you like weird ideas @Toxn, I'll @ you specifically So, with more modern APFSDS having smaller fins that the bourrelet fins of old, couldn't the bore size be reduced for many AP slingers? Reducing the bore diameter (down to roughly 90-95% of the fin diameter, but not to where the fins interact with the tube) might reduce the weight of the barrel, assuming it stays the same thickness, and would definitely reduce the mass of the carrying sabot, meaning more energy towards the penetrator. This might also mean savings to the weight of propellant needed to get a round up to a particular energy, or increase the energy of an already powerful round without increasing the propellant or chamber size. It might be possible to get a 105mm (or less) gun with a thicker barrel and larger chamber that your normal L7A or M68, but slinging full size 120mm (or larger, if the fins fit) sabots at targets. This gun might be somewhat lighter than the 120's, but I don't think by too much. I'm going to assume I'm not the first person to come up with this, and that there must be problems associated with doing something like this. I'm going to guess there are barrel droop and vibration problems, thought these might be less so than a normally designed gun because I specifically stated that the barrel stays the same thickness as the original gun (read: 120mm L/44) to cope with the (assumed) higher pressures of the larger parent gun. There's also the fact that the HE shells you will want to sling at infantry are also less effective, unless you make the HE abnormally long, which might also have hidden consequences like strange shrapnel dispersion or tumbling or something else you don't want. I'm disregarding HEAT due to it falling out of favor based on greater ERA usage across many combat vehicles, but it's problems would be similar to the HE shell. Any thoughts from anybody? I'm always open to being corrected and learning real world experience.

    Hmmmm, I just had a very weird idea, but it will have to wait until tomorrow for me to flesh it out.
  16. Lord_James
    Would the advantage of this be its low cost and easy / quick set up, compared to a normal bridge layer?
  17. Lord_James
    I’m sure there are diminishing returns on such things when bore caliber scales up, and barrel length will most definitely get excessive if you want a low pressure / high velocity 120 (I’m tempted to see how low a pressure you can achieve with a 120mm L/70 while still being a viable sabot shooter). Barrel droop will probably kill any guns this long, though, without reinforcing, which negates the light weight I’m going for.
  18. Lord_James
    Is it more efficient mass wise to have a gun with a longer barrel and lower pressures, or a shorter barrel and higher pressures? The 75mm PaK 42 seems to be about 1 ton by itself, while the similar 77mm HV is 1.5 tons (don’t have a source for the QF 17 lb without carriage).

    Where are the radars on that K808 SPAAG?
  20. Lord_James
    It’s also very similar to the Challenger 1 turret before TOGS.

    Can I use this mobility gimmick
  22. Lord_James
    Are we going to do a competition with wacky mobility gimmicks?

    PL-01’s cousin?

    TIL that the Italian's Pugliese torpedo defense system was actually not that bad. The flooding issue that comes up when criticizing this system is due to it's own passive counter flooding mechanism. Pugliese incorporated several channels that ran through the triple bottom of the Littorio's that, when one side is struck and flooded, would transfer water towards the other side automatically, meaning the ship would roll less and would (hopefully) require less attention from the crew and could continue fighting. Counter flooding was normally done on all battleships after torpedo damage, to balance out the weight of the water in those compartments. Where the Pugliese (and all torpedo defense of that time) had problems is that torpedoes with magnetic fuses that ran just below the ship could do significant damage, as seen in Taranto 1940. further reading here: The Littorio Class - Google Books
