Re: Indian Army unsure about Arjun tank's role
^^ thats the biggest problem with the Arjun
the tank is so big and so heavy that it needs a monster engine to power it and that coupled with the desert heat makes the arjun into an oven and thus they need an air conditioner
and that trains power and adds more weight
I think India should start all over again

that is why a cooling garment is being used or tested for desert conditions.

Besides, this logic may not be correct as even T-90 with a less powerful engine was showing problems in deserts of rajasthan.
Re: Indian Army unsure about Arjun tank's role
Importing European Tanks or building Tanks according to European design is not a good idea.
India has learned it the hard way.
I am surprised such a crucial thing like heat and geography of India never came up when designing this tank
Re: Indian Army unsure about Arjun tank's role
^^when heavy weight tanks like merkava, challenger and abrams can do well in the deserts of israel, iraq and others, then why not arjun can be like that. But inspite of it, there has been a miscalculation somewhere.
Re: Indian Army unsure about Arjun tank's role
The only tank used by the army which didn't have any complaints about its performance in rajasthan was T-72's with its 800 hp power engine. T-90's 1000 hp and arjun's 1400 hp engines have shown problems of overheating. Conclusion can only be that any tank whose power is way more than 800 hp, will eventually cause overheating in the Thar desert.

Nope, US M1A1 operate in Arab deserts they don't over heat, Our Al-Khalid passed trials in Sindh desert without over heating....

Then engine power doesn't have anything to do with overheating as mercenary said or the ONLY thing which causes overheating. It has to be something else also which is causing problems. Or perhaps climate in rajasthan desert is harsher than any of the deserts in which these tanks were tested, which is unlikely.

that was my explanation or rather conclusion, to mercenary taking his explanation as correct!

Your conclusion is incorrect w.r.t. to Horse Power.. Horse power requirements are directly proportional to weight. US M1A1/2 uses 1500HP engine, Al-Khalid uses 1200HP engine both tanks proved their worth in desert heat.
Re: Indian Army unsure about Arjun tank's role
^^so according to you it is power to weight ratio that matter. arjuns power to weight ratio is 24, M1A1 power to weight ratio is again 24, challeger-2 power/weight is ~20 and Al-khalid has power/weight of 26. The only difference here is M1A1 has a gas turbine engine and rest all have diesel engine.
So, still whether it is power or weight or power to weight ratio,i couldn't really attribute the reasons for this overheating thing.
Re: Indian Army unsure about Arjun tank's role
i heard arjuns MTU 838 engine is an older engine and europeans were not willing to give better and more powerfull engine. perhaps it is due to this older engine. But no body ever commented about this reason. But let me wait what happens after the final trials are done.

So its simple logic, one works and the other dont, And the one that works has lot more bells and whistles then the one that don't. Something wrong with ground up..

will wait for the final trials and army's reaction after that.

Was the tank redesigned so it could fit into the rail cars for transportation? I remember that was one of the issues????
Seriously, indians should have ditched the tank when they can get them from russia. If they really want to be indiginous then they should work on a new project based on the experiences of this one. I think the biggest problem in india is the bureaucracy that drags down every project.

no. the tank width remains the same. instead, the width of railcars were increased i guess. arjun has been transported to different parts of the country(from southern india to rajasthan). so that problem has been taken care of

Re: Indian Army unsure about Arjun tank's role
Let's see: it cannot move, catches fire and cannot shoot.
Obviously india designed this to be used by their airforece for target practice.
It is obviously a ruse to make pakistan believe they don't work
Re: Indian Army unsure about Arjun tank's role
Overheating was not the only problem. Arjun is** too heavy for the local terrain**, just like the European tanks. Most bridge like structures in the locality are made not to withstand so much weight, and a 60ton tank alone would certainly not be able to go through such places. And I am talking about Pak-India border. This was another transportation issue.
By the way, the project was started 24 years ago, not 34.
