China launches Asia's largest helicopter

The helicopter design by 2008,
prototype and trial in end of 2009
first flight march 18 2010 on google search.
there are more details regarding tech ones which I dont understand.


PS- this is civilian helicopter not sure whether it fits into this dhaaga but has uses in chinese occupied Tibet considering its potential implications in military.


it certainly helps when you have a Super Frelon to use as the base helo from which to begin the "new" design.

The aircraft is based on the Harbin Z-8 military helicopter, a derivative of the Aerospatiale SA321 Super Frelon that first flew in 1962

^exactly the reason we need ICBMs that influence the world rather just zonal specific Agni 5. When flight test the A6, the world will wake up and start joining to question about China's growing military nuisance.

If they begin attack.. better prepare for two things:
1. Pakistan joining in.. so, don't waste time.. look to flip a button to go MAD.
2. Get the numbers increasing on UCAVs and UAVs to monitory troupe movements - satellites should also augment here.
3. IAF be ready with all assets - the mountains needs IAF.

The faster IAF increases their squadron numbers, the better is the feeling for us.

More than ICBM, if an attack is imminent, India needs roads and border infrastructure to repel such attacks. Such infra is in place but still needs a lot of work. Agni ICBM is nowhere near to be operational and the Chinese plan would be limited attacks as mentioned in the article, more of quick attacks and then withdraw, giving it a flare-up look and feel. Such wars will be conventional and no party would want to go nuclear maybe. India has sufficient strength to repel such misadventures but only if more attention is paid to border infra and equipping the IA with modern howitzers et all, that would spare much pain to fight such wars. I still don't get the analogy of not developing border infra in fear that Chinese might use them even so many years after 1962, and only some 100 km stretch has been built.

There is nothing that can be done in a years time that can significantly alter the result.
The ramped up LACM production and the will to accept significantly higher casualties can probably save some face.

In this case produce INSAS/LMG/grenades/ammo/warm cloths/shoes/food in large quantities and store it on advance locations ..so that infantry can fire/use these without second thought of running out unlike 1962.

Everything else is luxury stuff in the end... e.g. Vietnam war

Interesting that he should mention June-July period. Monsoon during this period do not allow large scale maneuvers in the plans and hence, India is that much better off in the plains of Punjab. Though, PA might give some kind of "support" in the mountainous regions.

While the report is good, it doesn't state anything more than the usual line of thought being published in the newspapers. Giving a date and a title of probable Chinese attack is a bogey in itself. The report though serves good in bringing notice to the important issue of defense modernization and bogey sometimes do work in such cases.

see.. this is exactly we want to avoid no? like I told you so! and many people told you all so!.. yeah, we are not discussing of chances or capabilities.. Just the intention is quite strong, and that is enough for preparations.

But seriously, why would China want to attack now. Having capacity is great, but what would be the purpose. By the way this and the next year is a crucial period for China with the change over in the top leadership; as well as the risk of economic contagion spreading throughout the region. For example look at the fall in real estate prices, and especially the flood of money that was released in 2008-09 which now will have consequences. Adding in this flux, a war with India, just makes a complex situation more complex for China.

Further, a war as is being talked about, will be a limited war on the lines of the 1962 adventure. If this is true, in my humble opinion, any gains by China will be off-set by serving the purpose of completely focusing Indian will, capability and attention to the then clear and present danger of China. Also the re-armament process will cause India to enter into stronger relationships with USA. Further aggression by China will increase ASEAN fears, and drive them into the hands of the loose alliance of India-Russia-USA.

These articles are at best attempts to raise awareness and influence the re-orientation of citizens’ threat perspective from Pakistan to China and at worst naked fear-mongering.

China attacks India only when US is distracted by another war. This happened in 1962 and 1998. If China is preparing for a mid-2012 war, then it means they expect US to be embroiled in another war during that period - most likely in Iran.

That gives you the timeline of war against Iran - mid-2012,

In a way 2012 is a perfect time for China to attack,it is before the Arihant and her sister subs are inducted and are considered fully operational,before the Navy inducts any big ships or subs,before aircraft strength is ramped up with LCA,MMRCA,FGFA,MCA,UAV's,UCAV's,Mi-17's,LCH and many more.Also major border projects won't be completed by then,production of Brahmos,Nag,Agni-3,Akash,Agni-5 etc won't exactly be top notch.The Army also will be going through new challenges like raising new divisions,artillery purchases etc.In a situation like this China could do a "Kargil" on us,seize Arunachal Pradesh,undermine India's influence in the UNSC,ASEAN etc.Also if China humiliates India,countries like Vietnam and Japan will think twice about messing with it.The South China Sea dispute will literally crumble as countries will be afraid of China.Also the US would be distracted by Iran.
Just my 2 cents.

We really should stop this stupidity.
War may happen or may not.
However the above reason is not the reason why nations go to war.
(With the possible exception of TSPA)

Armed forces modernization is always an ongoing process.
There is nothing really special in how we are beefing up our defenses.

Every other month we have some anal-yst predicting when its going to happen.
Its turning out to be the like the end of the world predictions that I have heard for 1995, 2000, 2012 etc.

Chinese tank units training in snow conditions in Xinjiang

an armored regiment under the Xinjiang Military Area Command (MAC) of the Chinese People’s Liberation Army (PLA) took its troops to the snowy Tianshan Mountains to practice maneuvering, coordination, protection and resistance in lifelike battlefield environment set in complicated area, so as to enhance its troops’ mobile operation ability in arctic-alpine mountainous area

China invaded Tibet, in Oct-1950, when it was sending troops inside Korea to fight against the Americans. The reason given was "China is a neighbor of Korea". This is similar to what the Pakhis say w.r.t Afghanistan. It attacked India also during the Oct-1962, when the Cuban missile crisis was at its peak. So if we are expecting the *deleted* to behave rationally or follow logic, then we are living in a dream world.

In the 3rd pic, one can see what looks like a/c placed behind the turret within the grills. I think something similar will happen if IA opts for ECS aka a/c for T-90. Shows the acute limitation of space inside the russian design philosophy. That thing is going to glow like a sun when seen from a NVD/TI.

in that quadrant the engine is going to be hot anyway. note - it seems to be a AC not a more powerful APU for silent watch.

I can see a little face peering out from under the main gun in the 2nd pic, so I expect the wiper-equipped periscope in the 5th pic is the one on the turret next to the machine gun.

The sloped turret sides look nice but the inside is likely to be cramped and the tank appears susceptible to top attack.

Why would the Chinese put a huge a/c outside the tank for use in the world's coldest desert? For export to dealest plostitute maybe?

AC by definition has a heating mode also. its the dilli style desert coolers (a straw mat with water running down and air blowing through it) that can only cool.

which brings me to my next question. if T90xyz in our hands has neither a AC or a APU, how are they going to operate in the icy cold tibet nights ? or is there a russian jugaad way to warm the insides using air flowing in over the hot engines? (not useful when engines are shut though)

maybe we never fought in the day when it gets 45-50C inside per media reports? maybe we never had the extended kind of zipped up advances seen in Iraq where columns of tanks would move for hours in one shot through the desert?

Hmm i think if any thing else we would have rather been trained to fight during the day then at night , the TI and 3rd Gen IR thing is just a recent trend and even now many T-72 dont have it, they will be fighting with some discomfort or probably getting used to extreme heat or cold or just using a small fan :D

The tank is for export only if you read my header. I don' think its for Pakistan since they have their own Al Khalid program but Norinco had exported tanks to numerous customers and some of them are from hot desert environment.

Here is their own domestic tanks on PLA service it looks much heavier with some kind of shtora style protection system

AC for heating is very different from AC for cooling. Heating air is as simple as putting an electric coil and passing current through it. Cooling on the other hand is much more difficult as it requires a fairly complex thermodynamic cycle (generally a vapor compression cycle) to perform. This requires a compressor, a low temperature heat exchanger (for removing heat from the compartment) a high temperature heat exchanger (for dumping heat to the environment) and a throttling device (to expand the refrigerant so that it cools down).

The fan things that we see on rooftops (or behind the said tanks turret) is the high temp heat exchanger. This means that the designers want to cool something. If they wanted to heat something, they could have just put a high resistance coil and possibly a blower.

Chinese anyways donot use MBT2000. Mainly Pakis use them.

^^^The issue in high-altitude deserts is that sun-rays pass through a thinner filter and UV content is high (IMO)....the issue of sun-burns in humans is quite acute...especially, outsiders like tourists and troops. As far as temperature inside the tanks is concerned, the climate and temprature chart here (http://en.wikipedia.org/wiki/Leh) gives details. The temprature should be mangeable inside the tanks and OK for the latest electronic stuff to work properly.

But we sure will need a/c to keep troops warms and other such system for preventing the oil/lubricants from freezing over and to allow engine to start after a cold night in open terrain. The IA would have drawn up SOP for such things after deployment of T-72 in Leh in the mid-80s and continued deployment of BMP-II.

Cars in the UK in the bad old 80s mostly had heating only which was basically a fan that blew air over the radiator and into the cabin. Heating was trivial. The UK did not need cooling in the days before global warming. It is only cooling that requires the sort of heat exchanger fan that you see at the back of the tank. Looks like an afterthought. Like cycle with motor

Shiv,

It is inefficient to consume extra energy to produce heat when there is so much surplus heat being generated by the combustion motor. Bypass air is the most efficient way to provide heating to the passenger's compartment. It is still done that way. That's why you don't get heated air on cold days till your engine warms up even today.
