ADA Tejas (LCA) News and Discussions

I know that. But what I don't know is why that officer who spoke to Karthik (or was it someone else) from BR said that R-73 will be the standard missile on LCA.

Or was he just referring to LCA Mk1 and not MK2?

I think it might show up on Mk2, because the current pylon interface box on outboard pylons might be suited only for Russian missile. They are moving from individual pylon interface boxes to universal pylon interface computer on Mk2, which would allow it to carry any weapon on any pylon as far as it is within the weight range. This would mean it can carry BVR missiles or even a bunch of Nag missiles on outer pylons.

Python V on LCA will boost its capability the right way, along with Derby and the DASH IV HMD. Derby and Python V are of similar weight too and multi-ejector racks are present for both.

But, yeah, this answers my question.

Nevertheless, choosing Python V would mean discarding the range advantage the R-73 offers.

But we get this instead of the two channel IR detector,

Debry and Python are displayed as Navy use that on harriers .. ( BR link posted before where the interview was posted )

Israeli Missiles mainly for Navy where as Air-force is about R-73 and Astra / Meteor..

In this age of all aspect missiles and no escape zones using missiles guided by HMD, STR & ITR have very little role to play. BVR launches are done at nearly 1G with zero role rate. In a headon cross, R-73 has shown ability to be fired when opposition fighter is still in the forward sector and the missile being steered by HMD to turn nearly 120* to hit the target just when it crosses you again with zero roll rate. R-73 uses proportional navigation to hit its target. It is fired when the enemy is still in the fwd sector and than its seeker is help by HMD to look in a particular area by the pilot firing it. It locks on and turns even 150* to chase the target. Python-5 can be fired to hit targets behind you. The famous Pughachev Cobra is a way of firing missiles in an over the shoulder toss method to shoot down enemy aircraft who are behind you or chasing you. You give a Mig-29 or Su-30MKI just 500 meters around you in any plane, and he will be on your tail.

ofcourse most of today's air combat is about BVR MISSILES.

But still a fighter is rated on these stats like Twr, ITR, STR, RCS, for their effectiveness in case the missile combat is done, or, in case counter measures are deployed against them and when they enter the close combat stage in a do or die situation.

LCA MK2 will have single computer for interface with all weapon systems like F-35 & F-22. Mk1 has to be configured for each system separately. This stores control central computer is being developed as a JV with a foreign company. This will allow any weapon system to be launched from Mk2 once its interface is loaded on the main computer and the pylon will automatically detect the type of weapon loaded onto it.

Hmm, I thought we were building CIPs by ourselves.

LCA MK-II appears more like Jaguar. Are they planning to equip MK-II with some Jaguar USPs as well like enhanced CAS role radar evading low altitude flight profile etc. Whatever it be , it looks promising with some killer looks.

On the other hand air intakes seems small despite the provision of augmented air inlets by the side.

 

[ersakthivel]

What CEILMAC suggested was some improvements, which can be suggested to any other fighter. For example a US agency could have thrown the F-22 back saying you have no Helmet mounted targeting system at close range , and your planes are way too costly to maintain and stealth is usable only for strike roles which can be done better by cruise missiles.

A French agency could have thrown back the RAFALE saying you have a smaller radar than TYPHOON, and lower top speeds than TYPHOON,and not as good as TYPHOON in air to air specs.

A European agency could have thrown the TYPHOON back to it's makers saying it's strike role isn't finished yet , so no use in buying this hugely expensive plane for pure to air to air role, and faulty manufacturing process has limited your top speeds to 80 percent of it's specs due to unexplained vibrations.

If you have sent any SOVIET mig relic that is flying with IAF it would have threw back each and every one saying " ENDANGERING THE LIFE OF PILOTS EVEN IN PEACE TIME".

They haven't done so means there is something more to the plane than the words of any agency.

I have said many times and saying it again, What CEMILAC suggested was inprovements to reach the top supersonic NUMBER of TEJAS at sea leve i.e mach 1.2.

Since tejas has already achieved the same top speed of SUKHOIs and MIG-29 at sea level in Indian tropical conditions in flutter tests in the skies of GOA this suggestion is no longer a gospel of truth.

Flutter test procedure is as follows.

Tejas reached 4 km in altitude and SWITCHED OFF it's engines and took a dive and evaluated the performance of fighter in powerless dive.

And then while reaching sea level it re ignited it's engines and WENT PAST the same top speed of SUKHOIs and MIG-29 at sea level in Indian tropical conditions.

So it is not as if the TEJAS unable to overcome the non existent drag took a POWERED DIVE from 4km to go supersonic at sea level as some clueless posters are insisting.It is these clueless guys who are spreading the falsehood that as commented in CEMILAC report Tejas was unable to achieve it's top speed in sea level at and had to do a POWERED DIVE to achieve this. Truth points to the other direction.

CEMILAC report never faults ADA for decreasing the cross section from 4 to 5 meters in length along the fuselage(which would have violated the WHITCOMB's rule)

Consequently it is wrongly insinuated that this cross section smoothening problem was undoable in MK-1 and postponed to MK-2(another wishful thinking).
The length increase in MK-2 is to store some extra fuel to maintain the range to cater for the extra weight of engine and in Naval Mk-2's case some extra weight of strengthened landing gear.

Smoothening a fuselage cross section without increasing the length of the plane is no science fiction. Some guys even proclaimed there is no empirical evidence for this.

Even without knowing the proper meaning of the term Empirical evidence.Empirical refers to values of some constants that are used in design many mechanical components that have no clear validation using any other equation.

So we use certain constant number factors in fixing some design parameters of mechanical components in some equation that are perfected in practice over the years without any proof of defining formulas.

The guys who were proclaiming there is no empirical evidence should give their empirical evidence for various cross sections of Tejas fuselage at various lengths from the along the fuselage. Sure they are shooting their mouth without even an iota of ACTUAL EVIDENCE pointing to non existent issues.

The Jaguar doesn't really have any extra feature for deep penetration strike, apart from terrain following radar, which btw is a mode which can easily be done by other radars with sufficient processing ability.
The only reason it manages DPSA role is it flies very low.

Coming to the LCA, it is already superior to the Jaguar in most parameters, except range and payload. For mkii, the range would probably increase, though not by much.
It is this limited range that will limit its use for CAS, as on-air time will be much less without external fuel tanks or in flight refuelling.

But then it really was built as a point defence AC, with limited multirole ability. For its GSQR, it will do just fine, maybe even better than asked of it.

 

[Decklander]

Jag was good only for cold climate of UK. It is good at flying at low levels not bcoz of any special design feature but for lack of engine power. In 1979, son of babu Jagjivan ram and brother of present speaker of loksabha was interrogated for bribes for this Jag deal and like most other deals, inspite of clear evidence, nothing happened.

Gryazev-Shipunov GSh-23

The Gryazev-Shipunov GSh-23 (ГШ-23) is a twin-barreled 23 mm autocannon, The GSh-23 works on the Gast Gun principle developed by German engineer Karl Gast of the Vorwerk company. It is a twin-barreled weapon in which the firing action of one barrel operates the mechanism of the other. It provides a much faster rate of fire for lower mechanical wear than a single-barrel weapon, It had the unusual ability to fire infrared flares and chaff rounds, allowing it to function as both a weapon and a dispenser of anti-missile countermeasures, Its perhaps one of the most lightest Cannon at weight At 50kg mounted on a modern fighter, It has a rate of fire 3,600 rounds/min, The cannon is Manufactured at Ordnance Factory Tiruchirappalli India..

It's GSQR envisaged 4 tons weapon load and much longer range than the mig-21,which was built as a point defence fighter with no radar worth the name (so that it has to be guided from home radar base and hence the name point defence fighter.).

But IAF insisted on a much bigger weapon load ,range and very importantly much bigger radar(detection and tracking range (around 120 km).With mk-2 upgrades it is near about grippen NG in weapon load and radar detection range.

The Mig 27 in indian airforce has even huge cannon than this....
Is that gun also manufactured in india?

by 2017 the Mig27 is to be retired, so is there any plan to replace them.
or the Rafale of LCA will take its role to some extent?

 

[shuvo@y2k10]

can the gsh23 be mounted on a helicopters for closed firesupport role similar to american heli mounted m2 and miniguns?

 

[Kunal Biswas]

Rafale & LCA MK2 both, LCA MK-1 will be replacing Mig-21 Bis & MIG-21 Bisons..

by 2017 the Mig27 is to be retired, so is there any plan to replace them.or the Rafale of LCA will take its role to some extent?

Yes, there are 23mm Gsh gun/cannonpod that too made in India for MI-17

can the gsh23 be mounted on a helicopters for closed firesupport role similar to american heli mounted m2 and miniguns?

Sorry for missing the last update, going through a busy schedule. Also one can see that there is an addition mistake by ADA in this update. Will correct it in the next update.
