BS. Selex developed the swashplate technology for Eurofighter, an aircraft with a much larger radome dia than Tejas (Eurofighter 750mm, Tejas 650mm). Believe it or not, it combines the advantages of large FoV of a mechanical scan radar with the advantages of an electronically scanned array.
Inaccurate, Tejas has a much larger radome dia than Rafale and herein falls flat your argument. For reference
KAI T-50 - 490 mm
Mirage-2000 - 500 mm
Rafale - 550 mm
F-16- 740x480 mm oval.
Gripen - 600 mm
Tejas - 650 mm
Eurofighter - 750 mm.
PS: It's Gripen, not Grippen
After more than fifty posts you are for the first time accepting the basic truth ,that gripen has a radome dia 50 mm less than tejas!!!!
So the potential of any ASEA radar that gripen gets will be less in capacity to the same kind of ASEA solution that can be implemented in tejas ,
it is even more significant considering that ASEA radar can be used as powerful EW weapon all by itself,
This always differentiates tejas from the me too light fighters like Gripen,
because it can have a bigger radar which can be had only in 100 million dollar plus fighter,
Just imagine the force multiplier effort of this powerful radar sensor fused in future with AWACS and other ground radars ,
And it was the IAF demand for bigger radar and condition that tejas should within the foot print of Mig-21 which determined the length of the fighter and radome dia.
lesser diameter (600 mm )Swahplate ASEA on gripen may have a bigger field of view, But it will always be less powerful than the bigger 650 mm dia ASEA radar of tejas mk-2, meaning in the crucial frontal arc, tejas mk-2 asea wil always have the potential to host a more powerful ASEA radar with bigger range and higher sensitivity.
No swashplate solution can wish away this physical fact of higer powered ASEA radar, which you are skillfully dodging,
ofcourse the assumption is the number of TR modules and their capacity being the same,
You can also admit that same swashplate solution if implemented in tejas mk-2 will give it a much more powerful ASEA radar than that of gripen and Rafale,
I am sure IAF will in future demand such an arrangement, if the bigger swash plate asea field of view is favorable for it,
Ahem, Gripen's ES-05 by Selex is an impressive piece of equipment going by the specs released, especially the Field of View. The original PS-05 had very impressive specs of its own, only marginally lesser than original specs for El-2032. It is currently superior because Tejas has no AESA radar right now
Swashplates have a bigger field of view due to their angular positioning, but the crucial factor you are not mentioning as usual is the range and sensitivity of the ASEA radar is always determined by its diameter and the number of TR modules,No swash plate can arrangement can compensate for the lesser dia of radome,
And also the fact if such a swashplate solution is implemented in tejas the physical dia of the radar will be higher than that of rafale and gripen,
Nobody is denying that, rather it is officially stated. The whole argument was presented to correct a factual inaccuracy that Gripen will have 'PESA'.
You used a distorted picture with incorrect aspect ratio you found from google search to prove your measurements, it was merely pointed out to you as a friendly advice so as to not deviate your method. Stop crying over it.
Well , i was not physically measuring anything , with scale, i was only comparing ""RATIOS, if the picture is elongated in X axis , there will be no errors , while comparing ratios is something you are slyly dodging as usual, or you don't understand,
It will be true only if I compare a distance in Y axis to that in X axis,Since both the lengths are in X axis any elongation in X axis is not going to affect the ratio based comparison,
It didn't cross S-30Mki's speed. Here's the actual report.
Fighter aircraft Tejas clocks fastest speed during testing - Indian Express
Do you know which other 'Indian made fighter jet' was there ? Hf-24 Marut, which had problems going supersonic, even in a dive.
You can chose to live in your fantasy world forever , or accept the truth,
What is the top speed of SU-30 MKI at sea level in indian conditions? Any publicly available source for it? Come on accept that your mulish attempt to paint a draggy airframe picture on tejas by using the CEMILAC report was exposed with offiicial statement from IAF personnel explicitly saying that tejas achieved its top speed , And the subsequent ADA certification for IOC-2 with "supersonic at altitudes" , dive or no dive.
And you will continue to live in denial that in a powerless dive from 4Km a part of the engine thrust is required to change the flight path from downward direction to horizontal direction, Still it achieved those speeds in jet thrust sapping summer Goa skies is a slap in the face for guys using CEMILAC report to discredit the design of tejas,
Not according to me. I quoted the report verbatim without comments of my own. Here's a link to that :-
FA-50, really comparable to Tejas?
Those were Cemilac's words and not mine.
But without CEMILAC 's prescription of nose cone plug being implemented in tejas mk-1, it achieved its design sea level top speed, That was the point I was making, And that is the point on which you are silent even now,
how come?
Listen dude, I don't really know what your problem is, but
where exactly did I say that Tejas cannot got supersonic at sea level ?. I have always maintained that it struggles to go supersonic.
This is the exact reason why you were put on the ignore list, because of attributing stuff to people they never said.
Well i know your way of posting, is never making a point. It is always about casting aspersions by using reports in a skewed way, even after knowing that without the prescription implemented in the report, tejas mk-1 achieves supersonic topspeeds in inidan summer skies,
Btw, now that you have mentioned it, 1350 km/hr - 1.1 mach at 15 degree celcius.
At 30-35 degree celcius it is 1.05 mach
so, you are wrong again on a technicality
At the cost of redundancy, let me repeat.
I don't care what happens to Gripen program, because it isn't funded by my tax money., it may sink in the Baltic Sea for all I care.However in terms of project management and product delivery it is without comparison the single best managed aviation program in modern history. My only concern is with the Tejas program, so when a fanboy comes out and issues a blanket statement Tejas >> XYZ aircraft which is riddled with factual inaccuracies, I come forth and correct them, just because we expect better from our own institutions.
I did't expect you to stoop to the level of paki ranters posting as anonymous Indian tax payers,
Why the heck did single best managed international program crashed and killed its pilot with the first prototype itself?
SAAB over estimated its capacity and rushed through testing even without conducting regulatory safety checks is the unpalatable answer,
Situation was such that SAAB test pilots scurrying into VRS fearing their lives,Compare that to safety audit level in tejas program,
And the sweedesih airforce accepted gripen with much lower maturity level , so its induction was fast, but IAF wanted a complete product is the reason for delay along with international sanctions.Nothing Else?

In 1979, the Swedish government began development studies for an aircraft capable of fighter, attack and reconnaissance missions to replace the Saab 35 Draken and 37 Viggen. A new design from Saab was selected and developed as the JAS 39, first flying in 1988. Following two crashes during flight development and subsequent alterations to the aircraft's flight control software,
In 1979, the government started a study calling for a versatile platform capable of "JAS", standing for Jakt (air-to-air), Attack (air-to-surface), and Spaning (reconnaissance), indicating a multirole, or swingrole, fighter aircraft that can fulfill multiple roles during the same mission.
A number of Saab designs were accordingly reviewed, with the most promising being "Project 2105" (redesignated "Project 2108" and, later, "Project 2110"), recommended to the government by the Defence Materiel Administration (Försvarets Materielverk, or FMV).
In 1980, Industrigruppen JAS (IG JAS, "JAS Industry Group") was established as a joint venture by Saab-Scania, LM Ericsson, Svenska Radioaktiebolaget, Volvo Flygmotor and Försvarets Fabriksverk, the industrial wing of the Swedish armed forces.
The preferred aircraft was a single-engine, lightweight single-seater, embracing fly-by-wire technology, canards, and an aerodynamically unstable design.
The powerplant selected was the Volvo-Flygmotor RM12, a license-built derivative of the General Electric F404-400; engine development priorities were weight reduction and lowering component count.[14][15] On 30 June 1982, with approval from the Riksdag the FMV issued contracts worth SEK25.7 billion to prime contractor Saab covering five prototypes and an initial batch of 30 production aircraft.
December 1995
The 2000th Gripen test flight takes place. More than 90% of the scheduled test flights are now complete.
December 1996
The basic development work on the Gripen is concluded and the first Batch 2 aircraft is delivered to FMV
April 1998
An AIM-120 AMRAAM air-to-air missile is launched for the first time from a Gripen aircraft. The test is carried-out at FMV's Vidsel test range in Sweden and is the first AMRAAM trials launch ever conducted outside of the USA.
A Gripen fitted with a 'mock-up' air-to-air refuelling probe, conducts flight tests in the UK with a Royal Air Force VC-10 tanker. The trials include a 'dry' connection in-flight with the VC-10 NATO tanker.
It is decided that Saab AB is to be listed on the Stockholm Stock Exchange. 35% of the shares and capital are purchased by British Aerospace (now BAE Systems). The Investor AB group retains 36% of the votes and 20% of the capital.

For a project that started in 1979, it's tejas mk-2 equivalent has not entered production till now, despite continuous international involvement of international avionics biggies in all parts and fly by wire software of gripen,
When ADA asked for 4000 crores with faster LSP mode, the program was truncated to two TDs first to prove the tech and actual LSPs later with just 2000 crores as initial outlay,
So why you gripe here about tax payer's money?. Every tax payer can be proud of the fact that composite tech and avionics tech developed for tejas has found its way to SU-30 MKI program to such a level, that russian airforce is ordering 64 avionics and mission computers for their Su-30 MKI version from HAL,
Even if we produce a thousand tejas mk-2s here with SAAB assistance not a single tech from it will percolate to indian avionics industry,
I believe him. You, I don't for the reasons pointed above. Not that I detest people who disagree, but I definitely detest people who wouldn't listen to logic or reason and go on repeating misinterpretations again and again.
I can put your lack of trust in the waste basket without a concern, i don't care about anonymous tax payer concerns expounded by you here,I can found plenty of the same ranting by pakis across all forums,
You can shove your honest tax payer concern somewhere else,not here,
Done. Welcome back to my ignore list. Enjoy your stay on DFI while I take a vacation over the weekend. Ta-ta
