ammunition in turret bustle is protected with blowoff panels, reserve ammunition in hull is only spall protected however with water containers. direct hit will cause ammunition explosion.
it is pretty exceptional:
This is impossible -any single photo of right turret space shown that.More accurate >>
Arjun have decently designed hull, nobody questions that, the problem is that turret, redesign the turret, and problem will disappear.
Well this is a trade off, in the end unmanned turret will be nececity, and in the end all tanks will be designed that way.
Titanium?! Are you kidding? TE of Titanium against KE is only 0,8-0,9 which means that Titanium made armor plate 100mm thick is - 0,8-0,9 x 100 = 80-90mm RHAe, while for example Triple Hardness Steel have TE against KE 1,3 which means 1,3 x 100 = 130mm RHAe.
The same thing applies to T-90. The cooling problem - and it was resolved.
Indeed, as I said, similarly, the cooling problem of the T-90 was unacceptable. What is unacceptable and was is acceptable, is very subjective.
Unmanned turret is desirable, not a necessity.
Ok, if I try to debate you on this, we will go on for months, till this will end up like that copper melting in a shaped charge debate. Seriously, I know what I am talking about. Do read up on Titanium - please. Moreover, when I say Titanium, it does not mean pure Titanium, but Titanium alloys. I should have clarified that. Perhaps you do not know, Titanium has been used as armour in the past to reduce weight. This is not a new concept.
Installation of A/C unit is less a challenge than redesigning a turret.
So it seems protection was not a priority for DRDO.
Designers from a countries that are manufacturing tanks for a much longer times, think otherwise, it was nececity, for a very long time, it was not adopted due to being above technical capabilities at that time. Read about Object 450 for example.
Titanium alone might be usefull against smaller calliber ammunition. In case of tanks it is used in very small quanities or not used at all, because it does not offer increase in protection compared to other materials, it have only lower weight.
I mentioned Titanium because you and others were talking about weight reduction.
Thank you.
Heh... I would wish to have money from this, but I don't, neither Militarysta.
There is no relation, it is provided hardness for specific material in known hardness meassuring scale. For example it is difficult to find a hardness in BHN for WHA, but you can find it in Rockwell scale.
Ask yourself why nobody completely replaced steel with titanium, if it so such superior material.
@Damian, for example BHN is a measure of hardness where you take a ball and use it to apply force on a metal and then see the diameter of the dent on the metal and use that, and the diameter of the ball, and the force, and come up with a Brinnell Hardness Number. GPa is Giga Pascal, and one Pascal is 1 Newton force applied on a surface of 1 square meters. These are different things. The are not interconvertible. Therefore, that link you provided cannot be used to compare steel and Titanium, so that link is irrelevant.
Well, since you posted that link, I thought you would understand the stuff in the link. Now we know, that link compares apples with oranges.
Did you read that post of mine? Here, for the second time: http://defenceforumindia.com/forum/indian-army/44522-arjun-vs-t90-mbt-72.html#post652166
You cannot determine the hardness of all materials with the same tests, thus there are multiple different hardness scales. Some types of determining the hardness are largely redundant and only used because of different country using different systems (the Vickers Hardness Scale for example is mainly used by British/some former Commonwealth countries, Rockwell seems to be mainly used by Americans). Some units can easily converted to another, others are hardly convertable.
Because of costs. Titanium is much better when it comes to protection per weight and nearly as good as RHA (depending on the alloy). Some Titanium alloys weigh only 40% of the RHA required for the equivalent protection... this means you can (even though armour might get slightly thicker) replace the 15 tonnes heavy Chieftain turret with a 6 tonnes turret made out of high quality Titanium.
I doubt that only costs are sufficent explanation. It is possible to even weld such thick plates of Titanium? Or do cast Titanium would be as good as Steel? Without ballistic tests it is hard to say.
I didn't know that, seriously... Stop acting like a father if you do not understand the point, and try educating others.
I understand, it seems that you seek there things which does not exist, neither you understand what is written in that table.
Mechanical properties are not everything, it is also question as how thick plates from specific material can be made, and if these plates can be welded. For example THS plates are more efficent than RHA, but are also difficult to manufacture as thicker ones, and more difficult to weld.
