And Shiv was the first arm chair General who led BR in the 1971 war. During those Liberation times, he was wounded and awarded the Param chair on which he sits while giving gyan. I guess this explains why he dropped out as a dentist!! and this Param Chair, does it have holes for farting while posti...

What where they going to do?

karthik

Singha - I might be wrong, but I think its more to do with managing shock waves in the transonic region of flight I guess thats what the pilot meant.An powerful engine may draw air at super sonic speeds even during subsonic flights and hence choke itself out if the duct is not designed with proper ...

karthik

I think the good Col. has misunderstood the TP a little. AFAIK the Mk1 intake itself is enough for the current airflow requirements. a higher thrust engine for Mk2 would likely have higher airflow requirements and might necessitate a larger intake, at least that's the opinion of one informed friend...

deleted..

karthik

Why do some of the old members have their date of joining as 1975 or 80? Did they serve in the Army then or where they arm chair critiques since 1960?

karthik

I can't find HAL in their Website. HAL is not displaying any aircraft this year in Farnborough?

karthik

DELETED.

karthik

If i am not mistaken the Kaveri has more thrust than the older modeled F404 engine currently in the test variants of the Tejas? If its only some reliability and weight issue then there is no reason for us to condemn it, it would be better we had an flying version of the Kaveri may be on some two eng...

karthik

Any news on these Russians arrested in Jaipur, where they real spies and why is Moscow so jittery over the issue?

karthik

oh so now since you believe that the Mirage-2000 is outdated, it shouldn't be compared. Well, those are the specs that the IAF set. So what should we compare it to? JF-17 Thunder Bunder? F-16 ? Typhoon ? I already gave you the data on the Rafale which is in the range of 20-29 degs max AoA only, whi...

karthik

Karthik, the bolded part makes no sense what so ever. And that is what Kartik responded to. LCA hasn't been tested to the max designed AoA. And as documented numerous times, it is the first time they are doing such testing, and they are very cautious. They have roped in EADS to help them test the h...

karthik

Also they have not even tested the AOA of the aircraft yet how are the betting on the performance of the LCA if the angle of attack tests have not been carried out? One of the test pilot claimed it will experience flame out at 28degs and not that 28deg aoa is great by any standard! I hope they test...

karthik

Cant they add anti glare displays like in some laptops? This one seems to have too much reflection on it for comfort!

karthik

The Naval Tejas canards look little different, i wonder what advantage it give over the regular canard in the LCA? Also they have not even tested the AOA of the aircraft yet how are the betting on the performance of the LCA if the angle of attack tests have not been carried out? One of the test pilo...

I was in Kerala two months back, i climbed down from ooty and had to pass through Kerala in route to Goa. I and my friend where surprised to see the number of mosques there. Each street had minimum of 3 mosques. Its a fundamentalist state at the making and i wont be surprised if there is a separatis...

karthik

The navy version sure looks awesome, may be they can drop the nose in the AF version to if its only for making it sexy!

karthik

Is there a separate thread on discussing North-East issues? I cant find it anywhere may be i am missing it, can someone post it?

There is a documentary on Naga and Manipur conflict which i like to understand!

karthik

^^^ Have you worked out these parameters? Also do you know which airfoil the LCA uses to calculate the lift coefficient with respect to aoa?

karthik

Karthik, Please enlighten us as to what you mean by "Its seems to have an very slow turn rate compared to the JAS..." Do you have numerical evidence to support this, or is it just something you feel? My bad i should have asked before coming to a conclusion! That would be great if it does ...

karthik

For one let us not believe the TVC would increase the turn rate at a given speed. It will certainly let you do the turn much slowly and hence your radius of turn will be smaller. Tejas has a corner velocity where it has its best turn rate and best turn radius, i just hope its not too wide? TVC woul...

karthik

This sort of arm twisting will keep happening unless we start makeing our own turbines. It may sound weird but countries like Singapore or Brazil has a good pool of scientists that can collaborate well, if we had an memorandum with them we would have come farther on the kaveri by now, they also can ...

karthik

The cockpit is under the process of redesign.There was an article named "LCA cockpit to be pilots dream"! Hope it doesnt end up just as a dream! :D Anyone want to talk about LCAs maneuverability? Its seems to have an very slow turn rate compared to the JAS, was it designed keeping the TVC ...

karthik

^^^ Doesn't work for riots?!!

karthik

This outer cage would be very useful for vehicles in Riot hit areas, throw what ever stones you want or hit it with sticks and nothing happens to the vehicle! May be those gypsies need something like this RG-31 riot guard? http://www.armyrecognition.com/forum_pic/RG-31_Slat-armor_ArmyRecognition_For...

karthik

karthik - wouldn't it be better to encourage the man rather than assume he's going to do something? many modern writers are far more objective than the ones from even a few decades ago, never mind the 'old days' Everyone has some bias of some sort and a history buff definitely has some bias to his ...

karthik

...which will still make it 50 kg heavier then the design goal of 5 tons! 1% overweight!? :roll: Well thats aviation for you, weight matters a lot! 50kgs is like one pilot albeit a 15 year old girl pilot! :D Anyone know what is the armor in helicopter, Kevlar back panels behind metal like in armore...

karthik

UK still hosts a large variety of Islamists from all over the world, including from Hizb ut-Tahrir. Why? Thoba thoba, i remember i typed something critical about islam in 2002 and i was warned for being instigating! May be they had the hope back then that many Muslims may join the forum and if they...

pattan : can have various roots. It is available all along the coast - and we have mention of "Prabhasha-pattan" (the Somnath coast) . My personal candidate is pota-sthan. Pota==vessel, especially sea-river going vessel, for example a common Sanskrit usage is Arnaba-pota - ocean/sea-going...

karthik

The article states that Eurocopter and Agusta pulled out because they dont full fill the criteria which includes "high altitude landing!" It does not look like its only for low altitude duties! This makes the whole LCH thing seem meaningless if an heavier copter can take its place, althoug...

karthik

I read the news that IAF or Army is placing orders for Attack Helicopter to Russia and US? Why is that required when LCH looks better than either of them!!

karthik

I wanted to thank any BR moderator or Admin who unbanned me from the board! Looks like i back like Jaswant Singh!

karthik

Dear SvenLittkowski, I appreciate your effort in trying to learn and write about Indian History but may i ask what is your qualification in this field and how long you have been involved in it? Pardon me but the market place is littered with foreign writers on Indian History who have written half ba...

karthik

landing gears are tested on the ground to the limit loads. They do drop tests and they do a static strength test as well to ultimate loads. They measure both stresses and strains and so those hinges and mountings are not going to be used on the prototype unless they know it works. Add to that the f...

karthik

In your first quote , you said the shock absorber looks flimsy, and that was because you looked at your two wheeler's absorber. Based on you just reading a book and looking at a picture, you can pass judgements against something that has probably gone thru multiple reviews and simulation? And you c...

karthik

You do realize that there is a process called "certification" ? And that one of the certifications is that of crash worthiness. Means stressing the landing assembly (IIRC (de)accelerations of 25g due to crashes)? Not a nut or bolt goes in before it is twisted, turned, broken, weight measu...

karthik

Next time before Isro sends an 300crore Satellite i hope they safely cased in an reentry vehicle with parachutes so we dont have to make a colossal waist every time a rocket fails. It may be ok for uncles rich pocket but we need to figure out an way around this satellite dumping.

karthik

No need to get all smarty pants here, i have been watching this discussions for over an decade and i know how every newbie tries to manufacture an smart question just to impress the mods,seniors and get some recognition or whatever! The reason i asked it was because I have been learning about shock ...

karthik

Wow, Whats with the top shock absorber mounting!! Looks so flimsy.

Looks like some welded hinge is holding it on?

karthik

Yes I did, when you had first posted about that observation. Infact, that is the case with the F-22 and the F-35 as well! I dont know whether that was to get "clean" air to the elevators. It could be a by product of the wing design. [Speculation Alert ON] Inspite of the lifting bodies, th...
