2021-03-13 [2.5.0.23] Olifant Mk.2 Transmission and Neutral turn(turn on spot)


694096744_shot2021_03_1312_45_46.thumb.j

Currently Olifant Mk.2 has 5 forward gears and 2 reverse gears.

But I think it is very likely placeholder because it is just copy and paste from other Centurions.

On this site, we can see inside of Olifant Mk.2 from driver's seat.

On this photo, we can see there are 4 forwards and 1 reverse.

On this photo, we can see Olifant Mk.2 transmission is automatic because there is A setting(uses all 4 gear range) in gear range selector.

 

Although gear indicator has 1 reverse indicator, there should be 2 reverse gear.

BAE Systems has been awarded a follow-on contract for approximately £15 million by Armscor, the South African National Defence Force (SANDF) acquisition agency, for the upgrade of an additional batch of Olifant MK1B Main Battle Tanks (MBTs) to Mk2 standard.

According to BAE systems official news(archived), Olifant Mk.2 is upgraded product from Olifant Mk.1B.

As you can see Olifant Mk.1B has AMTRA III automatic transmission that has 4 forward gears and 2 reverse gears.

 

Quote

One of the key success factors of the upgrade programme has been the relationship between Land Systems OMC, suppliers and partners (Delkon, Reutech Defence Logistics and IST Dynamics), Armscor and the SA Army and will ensure success through the next phase.

https://web.archive.org/web/20061017050418/http://www.baesystems.com/newsroom/2005/sep/130905news186.htm

Olifant Mk.2 is upgraded by BAE Systems but local manufacturer has deep relationship with this upgrade.

Especially Land Systems OMC(currently Denel OMC) is manufacturer of Olifant Mk.1B and Delkon is local manufacturer that making power pack for armored vehicles.

 

So,

1. Olifant Mk.2 is upgrade product from Olifant Mk.1B.

2. Olifant Mk.1B has AMTRA III automatic transmission that has 4 forward gears and 2 reverse gears.

3. Olifant Mk.2 is upgraded by BAE Systems but there are partner local South African company that made Olifant Mk.1B and that makes power pack for armored vehicles.

4. Olifant Mk.2 has 4 forwards.

So I concluded Olifant Mk.2 has upgraded version of AMTRA III automatic transmission that is upgraded for new 1040hp engine.

Or it could be just AMTRA III itself because engine power difference between Mk.1B and Mk.2 is only about 90hp.

Then although there is only 1 reverse indicator but there are 2 reverse gears actually.

It is not problem because its transmission is automatic especially for reverse.

 

Also since it is automatic transmission, it should be hydromechanical transmission(transmission with torque convertor).

On this enhanced photo, I think left indicator is 'Oli Low Pressure' indicator that every hydromechanical transmission must have.

Or simply, automatic transmissions are usually hydromechanical transmission.

 

Currently War Thunder doesn't have proper mechanism for hydromechanical transmission, so every hydromechanical transmission gears in game are doubled to mimic varying gear ratio.

Then Olifant Mk.2 should have 8 forward gears and 4 reverse gears.

 

Unfortunately, there is almost no information about its specification but there are some mobility demonstration videos.

 

Developers must watch these videos and give suitable value to match vehicle performance with these videos.

And if Gaijin has access to IHS Jane's yearbooks, Jane's Armour and Artillery Upgrades 2002-2003 and other yearbooks could contain information about Olifant Mk.2 or AMTRA III transmission.

 

Conclusion

Olifant Mk.2 transmission needs total overhaul since currently it just has Centurion transmission settings.

Olifant Mk.2 should have 8 forward gears(doubled from 4) and 4 reverse gears(doubled from 2).

Its gear ratio should be decided by developers after watching mobility demonstration videos since its specification is unknown.

Then implemented mobility of Olifant Mk.2 performance should be matched with mobility demonstration videos.
