However, some correction is needed. Hydraulically assisted steering is only used in polish, czech and chinese (type69) versions. Soviet built tanks use servo springs, which make the tank easier to steer compared to T-34, but not by much. It is still fatiguing to drive these versions in the long term. The clutch is definitely not assisted at all, in any version. That is the feautre of the T-62. Heavy clutch, but not overly. Also, check out mastermilo82's youtube channel. The guy restores a Type-69 tank, he took it apart completely. Lots of interesting videos about the restoration of the gearbox and the steering system. It is in dutch, but there are english subtitles.

The empty racks can be seen in the photo you used to show the fighting compartment heater. Also the count of the rounds mentioned is 31 with the two i pointed out there are 33 so one is missing. And in the case of the t-55 there are also only 41 if you assume there are 32 rounds and 9 new so another two sould be somewere within the fighting compartment.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3103574899092646031.post-29693056002970183202018-01-25T14:58:54.634-08:002018-01-25T14:58:54.634-08:00Sorry for the late reply, I just saw your new comm...Sorry for the late reply, I just saw your new comment.

In said experiment a few measuring devices were put, and of course sheeps were "attacked" by the waveblast few times - one initial wave, and those reflected from the walls of vehicle. But that was not enough to hurt them, except of course eardrums ruptured. 2 or 16 sheeps were "dazed" and reverted to act normal after couple of minutes. So, as You see, it doesn't sound dangerous at all. So I think we can put "blast and overpressure" effects for the crew away :) At least until KV-2 will hit a tank, that is a different story, because that is literally few kilograms of explosives, I would not be surprised to see turret of most tanks popping up.<br /><br />But, on the other hand, 113 grams of explosives put into APHE shell (and THIS is enclosed space), are creating blast and gas pressure so strong, that walls of the closed case quickly become too weak to withstand the effects of explosion (actually that is kind of definition of enclosed space). Inside small shell 113 grams are more than enough to break it up in rather violent manner. And then fragmentation can hurt the crew members, of course. <br /><br />To add more light into "explosion in a tank" case, I've read two reports about HE round exploding inside manned tank (both 75 mm German HE rounds, say 700 grams of explosives, tanks were Comets or Shermans). Once two tankers were killed, the second time three. In both cases rest of the crew was able to leave the tank on their own (not completely unhurt, but still). And the third case was that HE round exploded inside the ammo rack (ammo was hit by German projectile and one HE exploded), and the tank was restored to service after "minor repairs". Crew already left the tank before explosion, luckily. But - minor repairs. Penetrating round caused no more fire or explosions, even said explosion did not caused that. IIRC, tank was penetrated 4-5 times. That's because tank interior is not a small area for such a explosion (especially that in third case probably all hatches were opened, and in first two - driver's hatch was opened).<br /><br />I can search for the "sheep" experiment if You want, gimme Your email and I will send it when I will find it :)<br /><br />Cheers!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3103574899092646031.post-30252574737285435432018-01-08T16:01:38.520-08:002018-01-08T16:01:38.520-08:00113 grams?

I would expect someone standing or sitting less than 1 m away from such a blast to be in recovery for the next few weeks, at least. The details of this experiment are very interesting indeed... <br /><br />Some interesting history about A-IX-2: it was specially developed for APHE shells even though regular hexal was available and was commonly used for APHE shells (for example H.10 in some German shells). I added more details to that part of the article and re-worded some of it to paint a clearer picture. Like you said, the idea was to have an incendiary effect secondary to the shattering effect.<br /><br />Breaking the shell into 100 smaller pieces would probably be better than 5-6 larger pieces, but that cannot be achieved with just 65 g of A-IX-2, I think :) That's the same amount used in 76mm APHE shells.Iron Drapeshttps://www.blogger.com/profile/07585842449654170007noreply@blogger.comtag:blogger.com,1999:blog-3103574899092646031.post-55493125118712576232018-01-08T11:42:07.334-08:002018-01-08T11:42:07.334-08:00Thanks, I will wait for that. I can already see th...Thanks, I will wait for that. I can already see that the blast effect is very questionable, especially compared to hand granade, which have significantly smaller amount of steel to break. The same way thick armor would consume blast of HESH, thick walls of APHE projectile will consume large portion of the blast of 65 grams of explosives. Ergo - it would be hand grenade that would produce bigger blast. Also, US experiments on live animals locked in small armored vehcile proved that 113 grams of pentolite is not having enough energy to knock out the animals, not mention to kill them. After detonation animals were alive and acting normal. <br />Also, a confined space is a relative term. Tank interior is not small space for 65 grams of explosives, it can be confined space to say 6,5 kg of TNT. but not 65 grams, especially when most of energy of those 65 grams is consumed by destroyed projectile. When it comes to air pressure, 65 grams of explosives are producing about 65 litres of air, so in tank interior - almost nothing.<br />Someone could say that adding more explosives would make the round more lethal, but I think otherwise. It was designed to break the round into few pieces (5-6 as You said), because they will be more deadly than 100 smaller pieces. And of course incendiary effect is important, if not major factor here.<br /><br />Anyway, I would love to see that report, I would probably learn some more from it :)<br /><br />Thanks again!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3103574899092646031.post-14528225367236345572018-01-08T00:11:57.374-08:002018-01-08T00:11:57.374-08:00I detailed the effect of BR-412B behind armour pla...I detailed the effect of BR-412B behind armour plate in the paragraphs above the one you quoted.

If the target is made of cast steel and not rolled steel, even better. Imagine a blast of armour fragments being ejected at extremely high speed into the tank, followed by shards of the eroded shell, followed by the shell itself, which may or may not be intact. If intact, the shell will explode and annihilate everything inside the tank shortly after clearing the armour plate. The MD-8 fuse embedded in the rear of the shell has a delay to ensure that the explosive charge detonates a certain distance inside the tank past the armour, making it more deadly than if it detonated immediately after perforating the armour plate, or as it penetrates the armour plate."<br /><br />Do You have any reference for that, any tests of this projectile behavior behind the plate?

The fume extractor seems to be just short of the muzzle. I have some problems differentiating the Type 62 from the Type 59, because I'm not so familiar with Chinese armour in general. As you seem to be a Chinese tank enthusiast, I would recommend this article to you regarding the armour protection of the Type 62: http://btvt.info/5library/vbtt_1979_04_type_62.htm As you said, it's poorly protected compared to a "real" tank!<br /><br />By the Type 63, I actually meant the APC, not the tank, but both were used. The text is admittedly rather vague on that part, so I'll get to fixing that as soon as I can.
