Q5 , IL â€“ 28 and J 8 aircraft but having low loiter time and insignificant throw weight I guess the analysis was right on track for those types. To place the issue in perspective, it would be well worth noting that most of the PLAAF airfields in TAR are at a higher altitude than Leh and Thoise. T...

So J-10 indeed can go 800 km with 3500 kg load even from airfield located at 12000 feet. Indeed. That is what surprised me the most. The Russian AL-31 engine is a very high performance type as compared to the other Chinese aero engines and is what allows the J-10 to carry that immense load at sea l...

Guys, Here's the one that everybody seems to have been asking for: CHINESE AIRPOWER IN TIBET: PART-4 ( J-10 PERFORMANCE ANALYSIS ) Typical launch airbase: Golmud, Tibet Role: AIR DEFENCE/ AIR SUPERIORITY Runway Length: 12000 FEET (GRAPH-2) LOAD-OUT CHART OPTIONS FOR GIVEN OPTIMIZATION: a) MAX LOAD p...

What kind of impact hosting J-10 and Flanker from Tibet has on the performance? I don't know that as of now, but I will definitely do that analysis at a later stage. However, what I am thinking is that given the range of these aircrafts (especially the Flanker; Not sure about the J-10 right now) an...

vivek_ahuja

Will wait for your analysis on J-7 but on the face of it J-7 will be worse than J-8II. True. But what I am aiming for here is to shed all possible light on the Chinese air power limitations in Tibet specifically since what th analysis is going to show is that despite all claims of chinese having th...

vivek_ahuja

Guys, I got hold of some additional material yesterday on the Chinese aero-engine technology. After some comparative analysis, it turned out that I had been over-compensating the Chinese engine performance in their favor. As a result I have provided the updated analysis (refer charts) for the Q-5 an...

There are four PRC air fields within 300 km to the Arunachal / Sikkim border. There only one within 50 km of the border. Based on your analysis we can say that Q-5 can only be staged from Nyingchi Kang Ko without refuelers. With refuelers hovering over the air field it can be deployed at max from a...

vivek_ahuja

J-8II is more likely to be deployed in fighter / interceptor role and not in CAS/ Attack role. It only needs to take off with air to air missiles which seems like your analysis shows it can very well do even from high altitude air fields in Tibet. Yeah, but still the range and endurance of the J-8I...

vivek_ahuja

Just an interesting conclusion for the J-8II: it turns out that the airbase penalty for this aircraft is at a minimum for variation in airbase altitude and only shows significant variation in airbase runway length. Something tells me that this aircraft was designed with operations in Tibet very much...

vivek_ahuja

Guys, Ran the model for the J-8II today after making changes to include time over target and the corresponding range issues. Also updated the Q-5/A-5 charts to include the same. Aditya, I will get to the map issue as soon as I have the data for all relevant aircraft. Currently I am doing these analy...

vivek_ahuja

My question was if there is a way to determine just the take off penality for PLAAF operating from Tibet vs IAF aircraft taking off from plains assuming the mission profile to be the same The IAF is unlikely to have take-off penalty from the plains at all, assuming the major airbases have sufficien...

vivek_ahuja

Okay, this is a different topic altogether. My analysis for the PLAAF aircrafts was mainly concentrated on the issue of their taking off from the ground being affected by altitude and runway length. this is because it takes a longer run on the runway to carry the same load in a PLAAF aircraft than i...

vivek_ahuja

Thanks. But I am still confused...if high altitudes cut down the range of the mission why will HI-LO-HI have more range than LO-LO-LO? Shouldn't it be other way around? Sorry about not explaining that better. What you have to consider here is also the drag issue. the higher you go, the lesser the d...

vivek_ahuja

And an additional things is that my Model takes into account the type of weapons the aircraft can carry. So while the model plays around with the fuel versus payload values, in the end it has determine what set of weapons it can carry. So the 500Kg value. The range of the A-5 can be increased furthe...

vivek_ahuja

This is the part I don't understand. The altitude of the airfield should have no impact on range when you are willing to sacrifice the payload for range except when altitude is such that aircraft cannot take off even with just fuel (no payload). But given that you show me that it is possible to tak...

vivek_ahuja

Okay. Let me understand what you are saying for your third scenario: sea level comparison for same range, but payload variations, right? In this case at sea level the A-5 on a LO-LO-LO profile is designed to move for 400Km on internal fuel with a payload of 2000Kg. whereas for Lhasa, at ~13000 feet,...

vivek_ahuja

Can you explain how are you plotting range of aircraft by altitude of the airfield? Are there any minimum payload requirements in your calculations? The reason I ask that is because I see that Q-5 payload is cut in half while its range is cut three times in your graph above. I would expect that it ...

vivek_ahuja

IMHO, the only true proper fighters that we can face and which meet these criteria of range without compromising significantly on payload are the Flankers. With a 1500 km radius, they can manage to deliver a moderate payload, and have enough initial thrust to manage a takeoff, and can settle into s...

vivek_ahuja

Guys, for an effective operational aircraft, it has to have at least 10-15 mins of fuel for repeated passes over the target area, and a similar reserve for emergency jettison. Please note that pilot SAR is for all intents and purposes infeasible in the Himalayan region. Operating radius is hence re...

Guys, Based on some of the arguments of the previous avatar of this thread, I have posted some of the analysis that I had some time ago regarding PLAAF Air-Power in Tibet. As you can imagine, the analysis is extremely convoluted and complex to present full in words here, but I figured you guys can u...

Micromanaging from New Delhi will fail since the decision making has to be dynamic and well-coordinated for the money to be spent wisely. Exactly.

The priority for development (in terms of security) is probably in the order: the border areas first followed by internal areas. Need to be able to facilitate troop movements on our side of the border to be secure from Chinese threats once development starts in the internal areas. True, but this de...

This infrastructure development thing is worth 60 Crore Rupees or around 15 Million dollars. So, how much development does that translate to? announced for improving transit facilities at Dehan, Siang, Siyom, Likabali and Missamari (all forward posts) And that's the bottom-line here. This money will...

Vivek, Wait on the NRSA thingy for now. I had sometime ago sent you a mail on the pics - but it bounced back. Let me send you that email and try my luck. Okay.
