    Was a KF41 tested? If so that definitely can carry 3 crew, manned turret and 8 dismounts - that was in the design brief for the vehicle and is a key discriminator.

    Very keen to see this. Prior GD turrets (LAV25) were cheap and cheerful basic bits of gear. Well out of date in all respects. GD has had a hiatus and I am sure that the new turret will reflect lessons learned and be an effort to leap over LANCE. Will suit 50mm of course.

    So your idea of apologizing is to call me a fanboy? Ironic, your hysterical response to anything other than fervent worship of all things Puma... and you call me a fanboy! Puma is a beautiful thing but like us all, flawed.

    Power densities and baseline dates. I think we have inconsistencies in the specified example engines. The 5TD is specified in its original form but the AVDS-1790 is specified in the 5A version at 908 hp which is a much later development. The 1960 AVDS-1790 is the 2A as used in the M60A1 which develops 750 hp. Both engines have later developments - 5TD up to 1050 hp. Very latest (2000s) AVDS-1790 up to 1,500 hp - that has common rail injection and modern electronics. Similar story with the 838. The early version with 850 hp is provided but there are later versions with 950 hp and the peak version has 1,400 hp. The point I am laboriously making is that the present baseline inflates the mass/volume power density of the AVDS.

    To hear is to obey.

    so my turret spec 1. 155 mm main gun - anti armour (kill Norman) 2. 75 mm coax - general purpose (HE, Frag etc.) 3. 8mm coax - anti-personnel 3. 15 mm remote with 8 mm coax = light vehicles and anti-personnel Auto loader for 155 operates over plus minus 10 degrees elevation, auto loader for 75 operates over 0 to 30 degrees elevation. This combo covers all threats at an ideal level. It packages nicely (in my head) so now to the modeling.

    Fascinating - we are all playing with the classic trinity. Firepower, Mobility, Protection. For me, in that order.
  8. DIADES
    and so you should. Love hybrid vigor!
  9. DIADES
    Absolutely, Recoverability, Continued Fightability demand it.

    The test would be along the lines of - is either half a fully functional vehicle or does one have to have both halves to do anything useful. A BvS10 meets the test - you need the whole thing to get stuff done. I am not going down this path, just racking my brain to find ways to use the nominally available mass total. I agree with Collimatrix's earlier post - no way anything conventionally configured and over about 100 tonne is doable in a mobility sense within the 4.0m width constraint. Even then, 100 tonnes requires serious suspension of disbelief. I am aiming at 75 tonne for my first pass.
  11. DIADES
    Of course the other way to do this is BvS10 style. That would allow twice the track on ground area and still be steerable. Most obvious compromise is loss of zero radius turn. This approach would allow a non-Maus 120 tonne vehicle.....
  12. DIADES
    Indeed it is - and it is perfect for that application. Maximum excavator slew speed is trivial, slew accuracy not required etc So, yeah, definitely a challenge to make to make an effective fighting vehicle in such a config
  13. DIADES
    Yep, per 2805662 above.
  14. DIADES
    I guess they were trying to keep turret size/swept diameter down because of the whole airborne idea. It is a neat autoloader but the whole thing compromised by a defunct requirement.
  15. DIADES
    OK, so ammon sometimes in the hull proper but even the autoloader ammo is essentially in the hull/turret crewed space? If so, this is a serious reversion to past bad ideas.
  16. DIADES
    That is going to need one hell of a traverse drive. Probably consume more power that required for mobility. And if the powerpack is in the turret ( the frigging enormous powerpack) then drive to the tracks is hydraulic or electric? Hydraulic has such poor efficiency that the powerpack would go from frigging enormous to double frigging enormous. If electric, bear in mind that we don't have fancy electronics so no brushless high efficiency stuff and even brushed stuff will have to use old school magnetic materials - no fancy rare earths.. Then there is CoG height and cross slope stability etc. But, it would be cool if you can make it work
  17. DIADES
    So, where is my design heading? 1. First pass - working up from the required lethality, making some assumptions around mobility. 2. Basic config and style chosen - forward turret, rear powerpack 3. Set turret size - how many crew, where is the ammo etc 4. What physical size and non-armour mass results 5 What armour mass is required to get acceptable protection 6 What is new total mass and size - do prior assumption still work? 6 Rinse and repeat until time runs out or acceptable outcome.

    Remember, the Cascadians are ever trying to use asymmetrical warfare to sow dissent.......
  19. DIADES
    So ammunition in the hull? What could possibly go wrong...
  20. DIADES
    Yep: Rule 1 - the customer is always right. Rule 2 - if the customer appears to be wrong, refer to rule 1 So, we have to offer the best solution within the bounds, let the games begin!
  21. DIADES
    Crew survivability is only 3rd priority. Continuing to fight is second so, fight til you die
  22. DIADES
    Wot! It were good enough fer grandad....
  23. DIADES
    My experience with AFV interiors is that they are too tight for ease of movement even if one was stark naked and fully greased up.......... Your body needs to conform to all the snags, lumps, protrusions and shit, your gear constantly gets caught. WHEN a vehicle brews up, you need out. Every gram and every millimeter of cloth/gear is a hindrance.
  24. DIADES
    Fair enough but good luck getting tank crews to wear armour. Too restrictive.
  25. DIADES
    ! that is even more basic that the stuff I was aware of! Note the curvature in the result - it is easier to make deliberately curved shapes than flat shapes.
