I have been reading up on british tank design and development and found that a gas turbine was tested in the conqueror chassis.

http://www.stilltime...as-turbine.html

 

Does anyone have any info on this ? as far as power output or range ?

Also if the Brits had this tech why didnt they use it for the Chieftain ?

Too expensive? Fuel consumption too high?

While I cannot directly speak for the Conqueror, I was still employed at AMX when two production models of the AMX 30, the Pluton and the Roland were equipped with turbines.

 

These turbines were Helicopters standard issue, adapted to run on diesel oil. Their purpose were twofold.

 

1) they were running a 380 Volts generator

2) they served to start the tanks main engine.

 

To start either the Pluton or the Roland, you would first run the turbine at 80%, and if you needed to start the main engine, then you would set it to 100%.

 

Later on came the Hyper-bar engine meant to run the prototype of the Leclerc. So the turbine assumed a third role. The engine could only run with highly pressurized fuel/air mixture, so their would be no way to start without the turbo compressor running. This was what the turbine did. Its exhaust was routed to blow into the huge turbo, to provide the necessary pressure for the engine to run.

The start up procedure was really intricate, and at the time, manual; each step had to be followed in a timely manner to achieve proper engine start. In case of a mishap, you had to run a specific fan to flush all the existing mixture from the inlet system for at least 10 minutes.

I am sure they have completely made the start-up automatic in the Leclerc. Hard to imagine needing to battle and fumbling with getting your tank going... lol...

 

But back to your topic, I believe that with all the embarked electronics, tanks need to have turbines to get enough power for all the gun controls, computers, and so on....

According to this source (page 14) the engine was rated at 1000hp. Not a great deal more than the 950hp the conq gets in game. Gas turbine could be a bit lighter though.

The Germans had a prototype Jagdtiger with a turbine engine but it ran too hot (650 degrees) and torched any cover it was likely to hide in

the best thing about turbines they could burn any type of fuel

Love the E100 chassis in your picture .

I read that they experimented with different ways to cool the gas turbine , the Germans I mean with the GT103 . Apparently America experimented with this design until the 70s .

 

I also found out that there was a propasal to put a 1400hp turbine in the T30/34/29 . In 1945 that would give them a similar hp to ton ratio as the Abrams .

The Abrams is 1500 hp @ 68 tons from what ive read or 72 tons for a combat load .The T series American tanks were 69 tons combat load according to the info .

 

I have also been reading the Germans tested the DB609 which was a v16 version of the DB603 . The engine used in the Maus , the 609 was only 10" or 267mm longer than the 603 . It produced 2660hp during testing and estimated 3400hp supercharged . For some reason they lost the funding to further test the 609 . 

If the Maus had been given the DB609 supercharged instead of the hybrid drive and 603 it would have a hp to ton ratio of 19hp/ton . 

 

Personally I think the best tank engine built was the Continental 1790 , still going strong today and new versions are putting out 1500hp .

I cant find the hp rating for the British turbine used in the conqueror test bed . I imagine it would have been 1200hp or so somewhere around the American and German turbines . 

 

Im curious to why they didnt try stuffing the Merlin v12 into a heavy tank . Its lightweight and puts out 2500hp from what I can find . 

I think its probably because the world armies decades ago dont have the supply chains we have currently . The abrams guzzles fuel but we can keep them refueled .

 

The Russians found out the hard way when they first deployed the T-80s and the crews didnt realize turbines burn more fuel while at idle and ran their tanks dry .

 

I think the Maybach 230 was probably the most lacking tank engine , even after the war when France had the original design team helping them try to improve it and get 1200hp out of it . It could only produce 850hp , some people will argue that the hl295 i think the French called it ? was not the HL230 . From what I could find it was built off of the hl230 a improved version .

The engines in game dont always have their real life hp ratings though . 

Turbines are alot lighter than diesel engines . There is a lighter turbine designed for the Abrams , 50% lighter but still 1500hp . It was not used because the turbine is already so light there isnt much advantage reducing weight in that department .
