Sorry to burst your bubble but diesel is better. Saudi Arabia wanted to by a Brazilian tank instead of the M1A1 because the turbine sucks in desert.
Also turbine has disadvantages in the following areas:
- Because of their lower efficiency, the thermal signature of a gas turbine is higher than a diesel engine at the same level of power output
- parts experience a higher wear due to their higher working speeds
- The turbine blades are also very sensitive to dust and fine sand, so that in desert operations special filters have to be carefully fitted and changed several times daily. An improperly fitted filter, or a single bullet or piece of shrapnel can render the filter useless, potentially damaging the engine
- much less fuel efficient, especially at low RPMs, requiring larger fuel tanks to achieve the same combat range
Also for Russian technology, Russians used the turbine engine in the T-80s. The Ukrainians changed them to diesels in T-84 and the new T-90 is a diesel.
Overall the M1A2 is a cold war tank. It is good in a battle against other tanks and an organized battle. In the new style of war that is happening in Chechnya, Iraq, Israel, etc it sucks. Russia and Israel are leading the way in the new tanks.
Well, I'm sorry, but your logic doesn't exactly jive with present-day reality.
The US military went with the turbine engine, because of it's power. If infact it was no longer the best power plant for their MBT, don't you think the US could have/would have replaced the gas turbine with a diesel power pack? It's a modular design, allowing a complete engine change to be made quickly and easily- even in the field. They have the money, the logistic train, and technical expertise to re-engine the entire fleet if need be.
A diesel may indeed be a more fuel-efficient engine type than a turbine, but it probably could not produce the power necessary to propel more than 70 tons of MBT with the acceleration and top speed that the gas turbine can attain. Remember, the Abrams is still one of the fastest tanks in the world, despite also being one of the heaviest armored. It's quite unlikely that a diesel engine could out-perform a turbine in the same size power pack. Remember, it still has to fit in the tank. Range and durability ARE certainly factors, but given the Abram's enormous weight- raw power is even more so. The Abram's sheer speed, and accelleration are among it's most impressive features- or the most terrifying, depending on your perspective.
Your statement about the Abrams being a "Cold War" tank is true, it was designed more than thirty years ago. But to say that it "sucks" in the "new war" enviroment is cleary false, when one looks at it's combat record during the last two Gulf Wars. Frankly, it has obliterated every other tank it has faced, including diesel-engined T72M's. Perhaps without the American's logistic capability, the Abrams would not have been such a successful tank, but then again, maybe it was also a well-designed war machine as well? If you've ever read about the Abram's development and how intense it was, you might have a better understanding of why it is still considered to be among the most successful combat-proven tank in service with any nation. To be sure, the same cannot be said about any modern Russian tank.
You can't make the claim that Russia is leading the way with new tanks, when the topic of this thread is about the LACK of a new Russian Tank. I have heard rumours about the existance of this pipe dream for years, and have read nearly everything written in English about the "Black Eagle". Clearly this tank is not going to be mass-produced by Russia, or any other country before the end of this decade. I doubt highly that it will ever serve in Russia, before land warfare involving MBT's is a thing of the past. It is very possible that that day may already be upon us.
Yes, the Israelis ARE on the cutting edge of new tank design, and the US is well on it's way to developing the replacement for the M1A2, the FCS program. The EU is making progress, as are the Chinese, the South Koreans, the Japanese, India, and Pakistan, among others. All of them EXCEPT Russia, actually. Perhaps you can provide a source that shows that Russia is factually "leading the way"? I'd greatly appreciate the fresh intel.
I realize that this is off-topic, as we're supposed to be talking about the no-show Black Eagle, so please forgive the intrusion.
As you were.
