The Tejas is similar in size to the Mirage III. It has simple inlets. Its engine is much lighter and shorter than the Atar 9C. It has a better sfc. Where is the problem with fuel ratio and space? A radar of the performance of the Grifo/ELTA has place in the nose-cone of a MiG-21, when the nose of Tejas offers more space. The possible adversaries will be F-16As/Mirages and F-7s.
Take “Janes” to find out, which size a radar-antenna has, which is housed in the nose-cone of each fighter.
Try explaining that too Arthur, the LCA nose was designed for a MMR size radar which is similar in size to the Gripen radar which oher memebrs never say is too small, sometimes I wonder. 🙂
The Lca WAS designed to beat the M2000 at least in aerodynamics, the M2000 which were new at the time were the benchmark, as far as beating other planes, we can only speculate, in any event an interesting info provided by Harry, MiG-29s beat Mirage 2000s 7:3 in IAF air exercises
Is this a pic of the PV1 or 2?
In conclusion, Yahoo has provided us with articles showing clearly that the LCA programme started in the late 80s, we know that the IMF induced Govt of 91 suspended funding for about a year, the LCA is obviously not as delayed as some would think, well so says the evidence anyway but what does that have to do with real life. 🙂
As for the nose dimensions, well wehave yet to receive data from a certain member, the best estimate was done by Crobto aka radar size about the same as the Grippen, which puts the LCA nose too small theory in the dustbin, besides if the LCA nose is too small, the logic must hold for the poor Gripen too. 🙂
The LCA obviously creates different vortices etc than the Viggen, pics have been shown, schematics etc, the proof is right on this thread for all to see, no specualation at all, the LCA has almost completed its entire flight envelope and will begin weapons testing later this year with the MMR, not bad, 3 years after first flight. MOnsoon rains obviously impede fast testing in the months of June-Aug but testing is still being done monsoon rains permitting. LCA avionics being used as part of the vetrivale, makes sense, a whole new infrastructure has been established, ADA chief comments that handling is better than expected, if we can take the Chinese designer comments about sd-10 as biblical truth, we must follow the same logic towards the ADA chief too non? 🙂
Assuming you are right then, someone should come back and recomment on his “fanboys, lca nose too small”, do you guys actually think that these designers were just sitting there eating their butter chicken while designing, then suddenly one said “oops we forgot to have more space for any other gear.” One should refrain from such comments when he does not have enough data or one looses his credibility.
Victor,
Thanks for the bit on the cockpit bulkheads, that’s finally heading to the info i was looking for to either confirm or deny my theories on the LCA’s short nose. I don’t get the ‘rear bulkhead’ bit though – is that the back end of the cockpit, or the bulkhead separating the cockpit section (remember that the pilot’s legs are quite a bit more forward than the actual cockpit itself)? Also, my compliments for the sarcasm. It’s been a while since something in that quality has been said in this thread 😉Sameer, Indian:
All the figures i gave in this are from Brassey’s World Aircraft & Systems Directory. I wonder if you actually read the same data as i gave though, i was actually asking you for data on the volume available for avionics between the cockpit and forward bulkhead. But alas, it won’t be a Zhuk-M aye?
There are no released data on the internal volume, hence it was idiotic of you to start claiming small noses before you know the dimensions aye, ahhh so you speculated, I did the same, we do not have the dimensions, just rough estimates with a probable high standard deviation, hence I can fit the Zhuk M into the LCA analogy still holds unless you provide me with dimensions of the internal volume of the nose area etc.
We have no clue as to how the LCA looks like internally, especiallly around the njose area, internal volume dimensions anyone?
nope, until then one should refrain from speculation and idiotic comments like the nose is too small blablabla, I have x ray vision blabla, you are all fanboys for saying the opposite blablabla. 🙂
Well then Crobato assuming that you are right and the LCA radar is similar to the Gripen radar, it does not make it that small now does it, Arthur you said that the nose is too small, well does your logic hold for the Gripen too and have you used that logic of yours more than once, the LCA radr is obviously big enough for the MMR, daa, and any radar that they will eventually make , aka AESA, post 2010. daa, so the nose is too small for what? People still seem to be confused about my Zhuk M comments, I like that, please read a few posts above.
All I see here are rough assumptions from people willing to see something, called data snooping, unless you can come up with numbers to back your claims, its worth nothing especially when you consider the inches differences that we are talking about, standard deviation etc, also a pic is a pic is a pic, what kind of camera, zoom, angle etc all matter but more importantly exact dimensions must be knowsn, and noone knows, and folks this is not the speculation thread, there are a few of them on other ton AFM but not this one, you give me numbers to back up your claims and speculation and I will oblige or else you are simply data snooping and loosing your credibility.
Yahoo can you provide me with the phd that you have, you seem to know measument while looking, impressive.
There are no dimensions for the LCA nose, we are dealing with inches here, Arthur claims that it is too small, well too small relative to what?
the M2000? Gripen?
then he must provide numbers to show the comparison and the dimension of those extra gear that won;’t apparently fit.
I am asking very scientific and logical questions here, or I will rvert to speculating, an accepted tool on the forum.
If one claims that a nose is too small, one must give dimensions, its clearly not too small for the MMR, I will also keep on claiming and speculating until then, its really easy.
bye for now
You are missing certain dimensions which were conviniently edited out 🙂
If Arthur can claim x and y without a source when noone really knows dimensions especially when dealing with differences of mm and inches cm etc, one can also make other claims which become equally valid. Its called speculation and seems to be acceptable without much critisism on other threads, we might as well start too. 🙂
Yahoo what seat nonsense, take a ruler and start measuring, I only understand numbers, it is not too obvious, is the diagram fit to exact scale, what is the error variable in making sucha diagram, is it 100% fit to scale? I do not know, do you?
We are dealing with inches here, no conclusive evidence can be given unless you have official numebrs. 🙂
goodnight
From thi diagram you can tell that it is so obvious that the LCA is nose is x inches smaller with x cm diameter smaller than a Mirage 2000?
woiw. uou really are something else.
Why you cannot see the Small Cockpit and from there the nose dimension comes. There is no such thing as measurement needed when every thing is so obvious.
No not really, I need dimensions not a cutaway brochure, sorry this is not a scientific answer, as far as it being obvious lol, give me a break, how can it be obvous, provide numbers to back this up,, Actually Arthur did, we are talking in terms of mm here, if you take stats you will understand this Arthur.
