Whatever makes you happy. My engineering started with this contest, what did you expect? I want my concept torn apart. I've no idea why there is no discussion afterwards, maybe others are afraid the issues of their designs might come out? I would also expect an exchange of opinions, but some made it so toxic it is likely not going to happen.
Anyway, I hope you don't mind discussing a bit more.
I've neither knowledge nor a feeling for materials. My idea for spaced construction was structural steel. Something akin to the vertical I (H) beam in the picture. The info on the stiffness growth is quite interesting.
1"-1.2" does seem too weak for a side plate in hindsight. I read somewhere that lower side of the Leopard 2 only has about 1" thickness. Maybe wrong info.
I think the weak front hull was indeed an error. Engine should survive impact in the frontal arc of 60 degs. I am satisfied if the rest protects the crew alone, it seems realistic.
I don't think any of those can hurt my crew with the setup and the specified angles. I wouldn't bet though. The engine is another thing.
Maybe is said it wrongly, the space for engine alone is more than 3 m^3. Actually it is slightly over 4 and the combined area for power pack is 8 m^3.
Main idea was the following
This is how it was supposed to look like.
I initially used EuroPowerPack as an ideal case. It should fit (note the radiator and fans of original engine stretch over the edge of the transmission below). By shifting coolers into sponsons it couldn't be exactly the HSWL 295TM but it is at least a probable combination. Then I compared sizes of older engines. Evidently, German engines are very compact. I also realised that "bits and bobs" wander around designs, I thought, depending on the space available. Such is the case of turbochargers already since ww2. Example in the image below.
I don't know enough to account for every component that might be missing from usual photos of the engines. I also realise now that in sponsons it might be a problem to propel the cooling fans.
You seem to be right about the space next to the driver. It would actually require narrowing the citadel.
I admit I never though about the forces and vibrations impacting the ammo. I had two boxes in mind that fill the breech as a assault rifle magazine by being pushed towards the middle from the outer sides by three bars traveling through each of the boxes. That was all quickly made up. I guess more thought would be needed here.
I haven't copied the cannon exactly, only the length. I made the thickened part of the barrel too short and pushed the barrel through the trunnion.
I don't know why you would call a two axis mount a farce. Maybe technically impossible, but it seems that modern tanks use a single axis only because it is the simplest solution that still does the job. With an auto-loader and shifting bulge already requiring a frame through the middle of the turret and hydraulics significantly reducing the space once occupied by the gearing, why not add a thing more. A wishful thinking perhaps.
