I found the following two links on Arjun Mk II. It looks absolutely cutting edge if what these two links say is correct. http://trishul-trident.blogspot.co.uk/2011/04/arjun-mk2-mbt-emerges.html http://www.facebook.com/note.php?note_id=152117238162818 Apparently the the gun and the armour are world b...

Rafael looks incredibly like LCA Tejas from a distance. I thought the wrong image had been posted at first.

AJames

A small diameter radar doesn't necessarily make Rafael inferior to Eurofighter. The radar is one of the biggest contributors to frontal radar cross section, and a mechanically scanned radar has a particularly large radar return - AESA is much better in this respect. Smaller radar and AESA means smal...

Did we get concessions for exporting smaller cars without duty? I rememebr Hyundai was saying the Duty was a problem for them to export cars made in India to EU. Otherwise rich get to buy expensive cars cheap, there being no benefit to India from this concession From the article, FTA seems to apply...

^^^ What is the indigenous content in Arjun Mk2, in fact we are going one step back from Arjun Mk1, dont call it arjun better call it something else, I hope the crew is Indian :( This is stating what should be obvious, but when you are talking about cutting edge technology, indigenous content will ...

another (who had actually flown Rafale) explained that “the Rafale is underpowered by comparison with Typhoon, and needs reheat where we would use dry. We can get through the Mach and supercruise in dry power at typical operating altitudes, and you simply can’t do that in Rafale.” The planned 90kN ...

AJames

One question with regards to Rafale. We do hear the common complaint that the nose of the plane is too small to hold a decent radar. What about the development (or pressure on Dassult to develop) a radar like the one on the T-50, Leading edge sensors..... this should help over come the small nose i...

That would kill the area ruling (see - I am such an expert - I know the words "area ruling - so there!)that has been used. the sunken cheeks I am sure is to produce an aerodynamically efficient body. Boss I am technically challenged myself ; to clarify I am of the view that of all the fighter ...

According to this Rafale's payload is unbelievable: http://www.strategypage.com/militaryforums/6-11248/page1.aspx Rafale has excellent payload for its small size. Officially Rafale C can carry a incredible 20900 pounds of payload despite the fact that it is slightly smaller than Typhoon which can c...

AJames

The Rafael would make an excellent choice. It has a wide range of air to air, air to ground, and naval weapon systems already integrated into it. It has an operating naval version capable of carrier operations. The only other aircraft that can match it for this multi-role and naval capability is the...

Those who are speaking of Ariane's "reliability" should check its initial successes and failure. Every move from preAriane (Europa) --> Ariane1 --> Ariane2 and so on had failures of 3-6 launches at the minimum. Infact Europa, was such a colossal failure that it was shut down without a sin...

AJames

The question is: are there any combustion cycle upper stage engines used by others, and do these have a good reliability rate? Why wasn't a cryo main stage used in GSLV rather than a cryo upper stage - was this for stage interchangeability with PSLV? What about the Russian cryo they use now on GSLV...

AJames

The PSLV reliability contrasts with GSLV failures. I think the problem with the GSLV is some basic design decisions that were taken early on which contribute to poor reliability. The main one is in my opinion the decision to start the cryogenic stage in mid-air. Cryogenic engines are inherently pro...

There is a cardinal rule in aircraft development that says that you should never develop a completely new airframe to go with a completely new engine. A new airframe should always use a known existing engine. The reason is that the power requirements for new airframes always go up, ... But if the p...

If there is a lesson in this, it is this. The IAF should have put their heart and minds fully into the LCA. But no, it was a step ******** child that they in all probably wished would have a still birth and couldn't be bothered with and studiously ignored it as far as possible and were probably mor...

I find the Tejas compound delta difficult to understand. I can easily understand the cranked arrow formation, ogee delta. The canards are similar in functionality like the leading edge extensions of the cranked arrow design. However, the Tejas wing is just opposite to all this. Please let me know (...

AJames

It is remarkable how close the wing plan of the LCA is to the PAK-FA (if you draw a straight line from the vortex flaps to the front wing tip). Stick a tail on it in the same proportions as the PAK-FA and you have a PAK-FLCA. http://www.militaryfactory.com/aircraft/imgs/sukhoi-pak-fa_2.jpg http://in...

AJames

Actually Prof Das argues that delta wings have inherent weaknesses that can only be addressed by FBW. Of course he has to "rub it in" by saying that even FBW only partially addresses the particular weakensses of the delta wing. Also he makes no mention of the advantages of the delta wing ...

AJames

I am not saying that an LCA trainer can fully replace type specific trainers, but it can reduce the numbers required, and greatly improve training over what is possible with the Hawk. In any case the IAF has type specific trainers for final familiarization with controls and displays and handling. If...

AJames

Could this mean ... if the AJT deal goes through further delays ... that a "simplified" version of the Tejas LCA make it as an AJT? Even that is not required - unless you want to remove the radar or some other weapons systems to save cost. The standard LCA trainer will do. The only additi...

AJames

If you are training for LCA, Mirage 2000, Su30MKI, Mig 29, Mig 23/27, Mig 21, Jaguar then there is no doubt the LCA trainer is going to be vastly better than the Hawk, and handling characteristics and the glass cockpit can be programmed to mimic each aircraft and can also transition from easy to har...

AJames

Cost is probably the main issue - although the Hawk is also very costly. Programmability of handling means it can mimic any other IAF fast jet. It may not be able to train for low speed landings though (eg. for training for a transport aircraft), though you can do this on the IJT. Maybe if more LCA ...

Hence the seeming docility of the LCA in earlier flights. It's just that much more complex. Well what I saw in the .mpeg movie is amazing. During development flights it is unusual to do close formation aerobatics which is risky. Even more amazing is the very low level aerobatic maneuvers. When this...

AJames

This is unheard of! Close formation aerobatics and very low level aerobatics at this stage of development. Must also be risky - no time to recover if there is a problem.

Attack helicopters should not be used as mud movers, but for anti-insurgency operations, to provide close supporting fire for commando operations, and it makes an effective anti-tank or precision air to ground weapon for instances where it is not going to come up against a lot of ground fire - in ot...

AJames

think in a situation like kashmir we can not say that a particular chopper can operate succesfully until it does performance in real conditions as the conditions in kashmir are too demanding. Helicopters are the most important weapon in Kashmir. They are the key to winning or losing a war in Kashmi...

AJames

An armed unjammable UAV would be nice and I certainly think India should be focusing on UAV technology, but with current technology you still need a human to make decisions and react quickly, although UAVs can help. For anti-insurgency operations and operations in rugged terrain, there is nothing be...

AJames

The high altitude capability requirements of Kashmir is pretty tough to meet even for unarmoured helicopters. Few unarmoured helicopters have the capability. That is why the ALH had difficulty in meeting the payload requirements and also Mi17s were used in Kargil as helicopter gunships. I doubt if t...

AJames

I think all this talk about the Apache and armed helicopters having failed is premature. As for Apaches being shot up in Karbala, only one was actually lost and that seems to have been due to mechanical failure. I think the Apache was used in the wrong way the same way British Tornados were shot dow...

Actually railcar (and submarine) based IRBMs and ICBMs make perfect sense for India, and road transporters don't. Road transporters are impossible to hide because India hasn't got large expanses of wasteland like China or Russia from where people can be excluded. This makes Indian road based missile...

Any idea why Ceylon changed its name to Sri Lanka ?

I think it is the same reason why Madras, Bombay and Calcutta are changing names - trying to replace colonial names with supposedly more historic names.

Anyway more interestingly how did Chennai get the name Madras?
