  1. Talk about Type90, i got some information from Chinese document which mention about the armor composite used on Type88 which is the prototype for Type90 recently. Not sure the exact truth but i would like to share. “Japanese Type88 tank's turret and hull composite armor were trying to use different ceramic material (Alumina、Silicon oxide or Silicon carbide ceramic cut in rectangle or hexagon),each layer using binder to bonded together. The protection of this armor can reach up equal to 400mm thick of armour steel (BK) and is capable of defeat 120mm high density KE projectile (muzzle velocity>1600m/s) fired from 200meters at 0 degree, and also capable to protect against the 120mm HEAT shell which capable of penetrating 600mm of armor. Besides, there are many of different type of armor plate, the use of ceramic material and it's ability of protection giving the armor research development a new direction” image10 Type88 tank's spaced (composite) armor structure. 陶瓷板=Ceramic plate 毫米=mm Other than this,japan seems are developing some kind of Kevlar composite It says:"Japan is currently develop a Kevlar fiber with Titanium alloy or aluminum structured multi-layer composite armor " Of course those are just for the prototype of type90, but we can try guessing the armor from this source: <<间隔(复合)装甲——现代坦克的主要装甲结构>>(1982) (Composite armor--the main structure of the armor for modern MBT) (1982) <<国外复合装甲中非金属材料的应用和研究概况>>(1983) (Summarize of the use and research of non-metallic material in foreign composite armor)(1983) ft.

  2. Guys, it's not over yet. And yes, I do have the original file, but for some obvious reasons I add some watermarks. Waffentrager is doing the same thing as he did on Warthunder forum. He is just bluffing with unknown source screenshots or photoshopped fake “documents”. He deleted every post arguing the pictures' authenticity to make himself “invulnurable”.

  3. I'm Miller Z from Waffentrager's personal blog as well as Warthunder forum. I once argued about the Japanese WWII Type 5 gun tank with Waffentrager in his blog and because I post out the correct information, not his fake ones, he deleted my replies. For details and more info you guys here can visit this link(post), it's in Chinese but you can still understand what I said with the help of translators or something else, or from the screenshots I gave. Just want every of you here know that this guy is a FAKE, a totally ignorant one. Here is the link: http://www.zhuangjiacheliang.com/forum.php?mod=viewthread&tid=797&extra=page%3D1 If you can't see the pictures in the link above, here is an alternative way. It's the same article I post somewhere else: https://www.weibo.com/ttarticle/p/show?id=2309404213101531682050

    That is indeed the argument that the Israeli's make in regards to the 1200hp engine in the Merkava 3. And it's true that the Renk transmission is more efficient than the Allison transmission in the M1. I suspect that when they claim to have similar power "at the drive sprocket", they are exaggerating a bit. Not all the power loss is in the transmission, there is also power loss from cooling systems and other engine accessories, so even a powerpack with a 100% efficient transmission will not produce it's stated gross HP at the sprocket. In case anyone ever wondered why the Merkava 1 has an engine with 908HP, that figure was intentional on the part of Teledyne Continental. The Israelis specified that they wanted a specific power output at the sprocket (I forget the number, but it was a round figure like 600 or 650) and the Teledyne engineers calculated they needed 908hp gross to get to that figure.

    More info to come soon. EDIT: Just posted it without reading so I don't get ninja'd. This appears to be a demonstrator turret for the automatic loading system.

  6. I've developed quite a fondness for art deco architecture over the last couple of years. Even the grayest, gloomiest and most monolithic edifices can be given an impressively majestic presence through the judicious use of angels, grotesques, bold geometric forms and gracefully pointy bits. Fewer things do a better job of saying "BOW BEFORE CHRIST". Boston Avenue Methodist Church And that art noveau's not bad either - specifically Gaudi's stuff around Barcelona.

  13. The Magach is truly an attractively rotund tank - like the Patton that went on the Big Mac diet - but I admit it would have been nice to have gotten the model with what I firmly believe were co-axial rave spotlights for psychological warfare.

  14. The British had some odd ideas about main battle tanks, although they wanted their MBT-80 to be more advanced in some aspects than the Challenger 2 currently operated by the British army... The lack of an indendepent sight for the commander was disliked The laser rangefinder of the M1 Abrams was incompatible with the thermal imager (?) For some reason the British military thought it was a bad idea to integrate daysight and thermal imager into a unitary optic The M1's fire control system resulted in a low hit probability (confirmed by statemens from US and German sources regarding the comparative trials of XM1 & Leopard 2AV) The armor of the M1 Abrams could be penetrated at ranges of 4,000 m by the 125 mm gun according to British estimates Storing ammo below the turret ring is/was seen as better than having a separated ammunition compartment at the rear of the turret because some US test proved that it might not always work with 105 mm ammo and wasn't tested with 120 mm; also the blast door needs to be open for reloading (silly complaint) Leopard 2's protection was "imbalanced" (sounds like the same complaint of the US military - too little side armor) and insufficient to stop a 125 mm APFSDS round (est. penetration 445 to 460 mm steel at 1,000 m according to the document) Shir 2 (that became the Challenger 1) was too heavy and also underpowered British believed it was impossible to modify XM1 Abrams' armor to stop 125 mm APFSDS ammo The drawing is from a 1975 patent by Krauss-Maffei. At this time the Leopard 2AV was being designeed. The patent topic are different ways to mount special armor in a main battle tank in order to allow replacing damaged armor modules, allow easier upgrading and allowing to completely remove the armor modules (which Krauss-Maffei suggested for traveling during peace time). The patent suggest three ways of mounting armor: mounting armor plates using screws (as done on the M1 Abrams) using armor elements that fit into a cavity and together (like the Z-shaped ones) without any sort of additional attachment putting the armor elements into "cages" or "boxes" with rubber-lined edges. The rubber-lined "cages" then are inserted with pressure into the cavities The patent menions that the Z-shaped layout would provide most protection but also requires most space. It is not mentioned what the armor elements are made of (only that they ideally use metal to allow easier mounting). As far as I understand all these drawings are placeholders and do not represent actual tanks or actual armor arrays. We know that all fully-assembled Leopard 2AV prototypes in the United States did not include special armor, only weight demonstrators. The special armor was send as armor modules for ballistic testing, which were only connected to a mock-up hull and turret. If they had already decided how this special armor would be mounted or not is unknown to me. IMO the most likely variant is the upper one (Fig. 7 and Fig. 8), i.e. the armor is mounted in boxes or cages. This would explain the box-shaped turret, makes replacing armor easier and fits to the drawings from Sweden. However I think that the actual armor might look closer to the Z-shaped arrangement form Fig. 5 (there is no reason why it should be impossible to mount the Z-shaped armor elements at different angles in a cage/box). The method using bolts seems to be the least likely, because the bolts would be visible from the outside, but only the smaller bolts holding the cover plate are visible on the Leopard 2AV and early batch Leopard 2 tanks - if the bolts were used, the coverplate would look like this:

  15. Thank you for your warm-hearted welcome! I am actually planning to post some articles regarding some older (IJA) Japanese tanks on the forum, I will always use the original and official archives. I hate cheaters and liars as much as you do

  16. ZhengZhou Police force around 90s Around the late 80s and early 90s most of the Chinese police force doesn't equip the Type 85(SVD). The only choice for medium range fire are picking the Type56semi(SKS)and mount with optic.

  17. US schools public are about turning out mindless little social justice warriors, who were supposed to vote Democrat, but now are going after their keeper/creators, science and freedom of speech instead. Reading, writing, and arithmetic are secondary thoughts, to be managed, so they do not interfere with the socialists er, I mean LGBTQAIP(P is for Pedophile) agenda. Since science is a white male power game, it had to go, what did science ever get us anyway, amiright?! The left can no longer call Christians anti-science because Christians believe in biological differences in the sexes. Plus, most anti vaccers are lefty lunes too, so they were already attacking science there too.

  19. Well, Andriej I also had with drawing measuments, and well the idea of asymetric turret is not typical. Looks realistic, but some small details suggests it is PSed - different sharpness of elements, colour, shadows etc.

  23. You are unlucky - in Wroclaw city where I live there is big LG corp factory whit many Korean Managers. And preatty close there is TAKATA and Toyota big factories. Funny I know people who know both - Korean and Japaneese language. And I had ask them about this whit kindly ask for translate. It cost me a lunch. And it's not about tank but indeed lenses. You are fucked in the ass misarable piece of shit who misinforms peoples here. Honestly - go to fuck yourself, and as many as it's possible dicks in to ass of you, your family and dog or other pet you have. GTFO!!!

  25. The people who care will homeschool, and the same standards apply for homeschooled kids as anywhere else. Well, sure. But my parents didn't have very much money at all, and mostly I was left to my own devices with a bunch of books. It's pretty amazing how self-motivated kids can be when you don't crush their souls in school. Right, and I'm not saying public school should go away. It needs reform, but in concept it's a good tool for people who lead a certain kind of life (either have to have both parents working, or they're a single parent, or whatever). But if the option is available, homeschooling does consistently produce better results. Well our public schools here in the US certainly are second- or third-rate. It's a sad truth. They badly need reform, and I think (sorry to say) it's the Left that obstructs that the most - though both sides are culpable.

  27. It also saved me from furiously trying to find the pictures I took of the shot up police ranges I've been to. Police ONLY ranges. With holes in the roof, the benches, etc. The Maricopa County range was one of the better ones, as it saw use by FBI and ATF. (Who were notorious for having repeated ND's with their select fire weapons.).

  29. You are also falling into the trap of thinking that the police are somehow better trained than citizens. Per capita, police have more negligent discharges of their duty firearms than concealed carry license holders. And depending on the department, police may only be required to train with their pistol once a year. If at all. I competed in pistol matches for four years. We had police come to shoot with us. And they were always the worst of the bunch. They were oftentimes cocky, and then they were beaten by a 52 year woman who makes us cookies every other match.

    Probably just what they have. The engine design bureau at Kharkov decamped for Chelyabinsk in 1941 and never returned. Most of the brain power behind engines was at either Leningrad or Chelyabinsk. Omsk and Stalin/Volgograd also had good teams for light tank engines. I think it is highly telling Kharkov didn't have an attached engine bureaus like the other factories did and did every thing in house. Also Uralmash did some cool stuff like the 16 cylinder engine in the Object 279. Edit: According to DAV Kharkov only did two noteworthy engine designs in the 45-65 period: 5TD and the 5TDF.

    Depictions of the human form were not really a big part of Migration Period peoples art forms and what they did create tended to be pretty crude. Sculpture did regress quite a bit from classical antiquity but If you look frescos, the images of people tend to resemble the same flat images the continued on through the middle ages. On the other looking at jewelry, gold work, and other such "tangible" items, you'll find really stunning works. It really wasn't until the very early Renaissance that we start seeing "real" looking people. Anyway, Picture of Winged Victory I took at the Louvre.
