Just to prove that it actually fits the crew. The dummy is 1,8m tall, so a bit taller than the California standard. 
Its actually surprisingly roomy, more roomy than I expected.

Its seems the new gun wont fit. It also looks hilariously out of proportion compared to the rest of the vehicle.

Nope, we're ignoring that.

What do you mean?
 
Will set of ATGMs and RPGs at the stated standoff.

10mm for the light threats.
Yes.
Yes. Counts as the equivalent metal (steel, HH or aluminum) thickness, at a 30% weight discount vs light threats and HEAT. Vs heavy KE threats it has a ME of 1 compared to its base metal, and a TE of 0.7. (And an areal density 0.7 of its base metal of course).
 
Ribbed armor is considered offensive.

See, that's just silly. There's no fume extractor or thermal sleeve or anything!

So I have been working on a schematic for my hydrostatic transmission.

 
In short, its a hydraulic open circuit. A swash plate pump delivers the power to the system.  A over pressure valve makes sure excess pressure and pressure spikes are vented into the reservoir. The power is split by a distributor valve, acting as a sort of differential lock in the case of a track slipping.  The flow is then regulated by a flow valve  that feeds into a direction changer valve. It feeds the hydraulic motor, also a swash plate motor. In parallel, it has a freewheel valve for when you simply want the vehicle to rotate freely. Both feed back into the reservoir.  A accumulator is also hooked into the high pressure side of the system, providing regenerative breaking and smoothing out the power delivered to and from the motors. 
 
This is just a first draft, I will most likely add more safety features and refine the system. Also it lacks the auxiliary equipment like the suspension.  I am also researching ways of making the pump more efficient past simply running constantly and the excess pressure being vented into the reservoir, wasted. Maybe also making the pump into a starter for the engine.  I also lack the oil cooler. 
 
I have been pondering on using two engines to power the system, one for each motor, or two pumps. The issue would be that power could not be shared between the motors and same with regenerative breaks. 
 
 
 

 
I am also working on the hydropneumatic suspension. This is a schematic for the front and rear most road wheels.  Pressure is feed into a 3/4 valve which is used elevate the roadwheel, a over pressure valve is used to regulate the amount it elevates. Outside of that, the pressure is fed though a over pressure valve that regulates the height of the suspension.  Then a accumulator is coupled in parallel to provide the "springyness". Before the hydraulic cylinder is a flow valve, which regulates the amount of flow, that is used to modify the stiffness of the suspension. 
 
This system is feed by the open circuit shown above in the first picture. 
 
 
And yes, everything is written in Norwegian, because diversity, a core principle of the most supreme state. 
And yes, it was all hand written while cutting steel, because I lack proper schematic software.

Taking your idea, I came up with something like this. 

 
A pressure sensor sits on the accumulator. When the accumulator compresses, it compresses a hydraulic fluid which controls the engine throttle, the more the accumulator is compressed, the less throttle the engine gets. Also, when at the dead bottom, it activates a valve which decouples the prime mover from the pump and locks it hydraulically, while also bypassing it with a check valve. 
 
I could add a hydraulic/pneumatic PID for more precise control. Also note that the control lines are simplified, and probably will be changed to better reflect their behavior later. 
 
And thanks, I almost flipped my table when I noticed the missing line. Luckily it is too heavy. 
 
 
EDIT:
Updated my schematic with a PID, am wondering if I should use a electric PID instead of a hydraulic. A worry would be lack of pressure could stop the system. 

 
I think I might need a separate flow chart for the control engineering.  One schematic for the main hydraulics, and one for the control scheme. 
 
Edit:
Damn, the spring in the clutch cylinder is on the wrong side. Please ignore.

Hydraulic efficiency is not that bad in a closed loop system with a swash plate pump.  Around 80-85%.  Combined with accumulators and very good torque characteristics and they are not that bad. 
When it comes to electric propulsion, simply use two engines, two generators and two motors. Efficiency should be pretty good here, if you can handle the catching on fire and dual engine stuff. 
 
I probably wont design a all turret tank, though I like having the option. Maybe if I got some extra time. 
 
I am more aiming at learning and being creative in this competition than actually winning. 
 
 
For now, I am thinking about a Strv 103-BV206 hybrid with hydraulic drive. IF I can't have my microprocessors and transistors, I damn well am going to have my special tank.

Imagine a BV206, only that everything can rotate 360 degrees.  Like a excavator. 
Because I am sure our superior drivers can cope with the sudden rotation of his workstation and sometimes complete lack of vision while guiding his vehicle through narrow mountain roads. No less should be expected. 
 
In a way, the vehicle would be a turret on tracks. Kinda like this:

 
Also, welcome Zadlo to the forum and this GLORIES competition, I am looking forward to your great contribution to the greater good.

This issue seems to be blown out of proportions. 
 
I have a friend who is doing his service time as a conscript in Panserbataljonen.  He has not heard anything about this issue. They also train with kampeskadronen. 
 
It does seem that some CV90s have a manufacturing fault, with welds causing the leak apparently. It is also rumored that one affect CV90 has had leaks since it was adopted.  Though it would not really be surprising, Forsvaret is a mess from what I have been told. 
 
This is at least what I have heard. I can translate the articles from Teknisk Ukemagasin if anyone is interested.

As far as I am aware, Sweden was only inspired by the US to test DU armor themselves.
 
Original:
" Inspirerade av den valda skyddslösningen i den amerikanska stridsvagnen M1A1 DU där Chobhampansaret uppgraderats med skikt av utarmat uran, gjordes provskjutningar i Sverige även mot denna typ av material. Resultaten visade på möjligheten att nå bättre skyddsprestanda om volymen och inte vikten var gränssättande. "

" Inspired by the american armor solution in the M1A1 DU main battle tank, in which the Chobham armor was upgraded with layer of depleted uranium, a test was conducted in Sweden of this type of material. The results showed that if was possible to increase armor protection if volume, but not the weight was the limiting factor. "
 
In short, they tested a home made armor, and concluded it was only worth it if volume was the constraint, not the weight.

As you all know, I am Norwegian. And I think we do camping a bit different from the average person from the US.
 
Here in Norway we have the allemannsretten law, which in simplified terms means anyone can go anywhere. No need to concern about private property when hiking. 
So how most Norwegians hike, is by driving/walking to the foot of the mountain/area they wish to hike and then traveling to your destination. We have no designated camping spots in the same manner as in the US. So you have to find a good spot yourself. We also lack prepared trails usually, unless it is heavily used.  We can also chop down trees and vegetation to make a campsite or a fire, as long as you don't leave a big scar. 
Campfire rules are simple, don't light them between the specified months, except in mountainous terrain or besides lakes/oceans.  And also try and stay at least 200m from trails or cabins. 
 
I have friends in the US that laughed at me about how much equipment I usually carried while camping, saying you could just sleep on the hood. 
I find it hard however to get a truck up here:

 
What you see here is heavy fog obscuring a steep drop into a river, probably a 50m fall. We have a use a set of chains bolted into the cliff face to get past this area.
 
Here is good view of the valley further up when the fog is gone:

 
The weather was kinda meh this day, demonstrated by my friend:

 
For those that wonder, we went to a place called Molladalen, very beautiful place. You ascend about 800m I believe, so a easy trip. 
 
 
 
 
 
I sometimes go hiking in the mountains when I am bored, usually I don't need more than a jacket or a par of sunglasses if the weather is not shitty. 

 
 
 
 
 
 
Anyone interested in winter hiking? It is by far my favorite:

 
 
I love it, well as long as I remember to check my hands and feet once in awhile, almost lost my hand once.
