ADA Tejas (LCA) News and Discussions

[WolfPack86]

I hope Indian Air Force to have 40 Tejas in 2 years.

 

[WolfPack86]

I hope HAL will deliver remaining Tejas very soon.

Bhai hal is in turbo mode add ..more 4 jets in. this year

already 7 inducted....sp 8 took the sky
then sp9..will be in sky in this fiscal year

then up to sp 12 are in different stages. so add 4+ jets in this year

 

[Sancho]

Yes I believe the actual production time for LCA is 11 months (9 months is the target) and I think I've heard 2-3 years lead-in time for sub-asembly orders from suppliers but I could be wrong.

Interview with HAL CMD: ‘No frozen standard of preparation of LCA… that’s where delays are coming’

...As far as the FOC order is concerned, mid-2018 is when FOC is expected to come but we are asking the customer (IAF) to allow us to cut the material. Because if we start now, the aircraft will come after three years. By then, this AON of 83 LCA will be converted into a contract between the IAF and HAL. However, today the facilities are on and the rate at which jigs are created are available, and the purchase orders can be verified and checked...

IAF commits to 324 Tejas fighters, provided a good Mark-II jet is delivered

HIGHLIGHTS

• IAF has “firmly committed” to 123 Tejas jets at present, which will come at a cost of over Rs 75,000 crore
• It wants the next 201 Tejas Mark-II jets to be “entirely new fighters” with much better avionics and radars
• The existing single-engine Tejas has limited “endurance” of just an hour, with a “radius of action” of only 350-400-km

NEW DELHI: After years of being critical of the Tejas fighter, which is still not combat-ready 35 years after the light combat aircraft project was first approved by the government, the IAF has now agreed to induct 324 of the indigenous jets in the long-term to make up for its fast-depleting number of fighter squadrons.

IAF has “firmly committed” to 123 Tejas jets at present, which will come at a cost of over Rs 75,000 crore if both developmental and production costs are taken into account. But it wants the next 201 Tejas Mark-II jets to be “entirely new fighters” with much better avionics and radars, enhanced fuel and weapons carrying capacity, and more powerful engines, say top sources.

The existing single-engine Tejas has limited “endurance” of just an hour, with a “radius of action” of only 350-400-km, and weapon-carrying capacity of 3-tonne. Other single-engine fighters like Swedish Gripen-E and American F-16 have roughly double the weapon-carrying capacity and triple the endurance.

But IAF, down to just 31 fighter squadrons (18 jets in each) when at least 42 are required to tackle the “collusive threat” from China and Pakistan, realises inducting expensive foreign fighters “in large numbers” is simply not an option.

The 36 Rafale jets, ordered from France in September 2016, for instance, have cost India Rs 59,000 crore. The total cost, of course, includes a decidedly deadly weapons package, all spares and costs for 75% fleet availability and “performance-based logistics support” for five years.

“The Tejas Mark-II is still on the drawing board. But if DRDO, Aeronautical Development Agency and Hindustan Aeronautics Ltd deliver the required Mark-II fighter, IAF has agreed to have a total of 18 Tejas squadrons,” said a source.

This comes after a flurry of top-level meetings in South Block, with defence minister Nirmala Sitharaman herself announcing earlier this month that the government is “not ditching” the home-grown Tejas and “putting all its energies” into ensuring the fighter is delivered at a much faster pace.

Only six of the 20 Tejas ordered by IAF in their IOC (initial operational clearance) configuration, which basically means the fighter is airworthy, have been delivered by HAL till now under the first Rs 2,813 crore contract inked in March 2006.

Another 20 Tejas in their FOC (final operational clearance) or combat-ready configuration were to be delivered by December 2016, as per the second Rs 5,989 crore contract inked in December 2010. But the Tejas will get its FOC only by June at the earliest, with IAF now hoping to begin inducting these 20 jets from 2019 onwards.

The contract for 83 Tejas Mark-1A fighters, which will cost around 50,000 crores, is in the process of being finalized now. These jets will have 43 “improvements” to improve maintainability, AESA (active electronically scanned array) radar to replace existing mechanically-steered radar, mid-air refuelling capability, long-range BVR (beyond visual range) missiles and advanced electronic warfare to jam enemy radars and missiles. The delivery of these 83 jets is slated to begin in 2023.

SP-8 in takes first flight

 

[Narasimh]

Tejas should be converted to un-manned unit and the flight parameters which have been restricted for human flight can be relaxed further to allow full envelope of flight. It can turn harder and carry more fuel and get rid of the pilot specific instruments.. The key to success in our aerospace capability will be defined by how good our Electronics Research and Development is. Electronics should be top priority under Make in India.

HAL to deliver three Tejas planes by month-end

The count of planes in the IAF’s first Tejas squadron will increase to nine from six.
Updated: Mar 16, 2018 23:11:56

Plane maker Hindustan Aeronautics Limited (HAL) said it plans to deliver three more light combat aircraft to the Indian Air Force (IAF) by the end of March, taking the count of planes in the IAF’s first Tejas squadron from six to nine.

“With increased level of outsourcing and capacity augmentation within HAL, we will be able to speed up the deliveries to cater to the present and future requirements,” said an HAL official, who did not wish to be identified.

HT reported on Friday that LCA production woes had led to disenchantment and frustration in the IAF that has ordered 123 such planes and plans to order 201 more upgraded variants to arrest a sharp decline in its combat capabilities. Schedules get disturbed due to modifications made (in the platform) from time to time, the person quoted above said.




“The IAF is nearing 1,000 sorties after formation of 45 Squadron in July 2016. It is significant in the LCA programme,” the official added.

“HAL is working on ramping up the production capacity from eight to 16 aircraft per annum from 2019 as agreed with the IAF.” He said major sub-assemblies, including front fuselage, centre fuselage, rear fuselage and wings, had been outsourced to private industry.

The government is aware about IAF’s concerns about the Tejas production rate. On March 3, defence minister Nirmala Sitharaman said HAL had been asked to scale up the Tejas production rate and deliver the upgraded Mk-II version at the earliest.

----------
* 1000 sorties with 6 aircrafts is a great achievement of No. 45 squadron.

I think it goes this way......

They first reach out to HAL official for the info, he might be busy and says FFFF OFF.

With no official source, they use their own imagination and compose some shit and give "unnamed official" touch.

ADA proved you wrong on the fuel tanks needed for strike loads

ROFL!!!

As I guessed earlier, you have no clue about range, mission profile, flight profile and role of drop tanks in those.

As far as ADA is concerned. Well, they are not any Tom, Dick and Harry. That is why they were doing this(see pic) wrt Strike Missions.

Try a microscope to find any Drop Tanks on inner-board stations. Beloved ADA is proving wrong again, but you!

and here once again they prove you to be wrong:

http://i64.tinypic.com/1rt3e0.jpg

Their "proposal" is to remain with 2 x missiles max and even that is not an approved solution so far, since we reportedly have problems with the integration of Python V and we don't know which SPJ will be selected with what weight...

These are just two of many configurations tried.

Still, if one station can carry a type of load, theoretically its mirror station on another side can also carry the same. Anyone with the slightest understanding of things knows it.

However same is not true for Toms Dicks and Harrys.

Who says you can't? But it doesn't solve the problem! You still have only the mid wing station to carry either missiles or bombs, so in strike configs, you can carry 2 x 250 to 500lb bombs, but still have no hardpoints for missiles.

Check the pic posted above, with a microscope may be. ..........Again you are proven wrong by ADA. ROFL!

In CAP the addition of a twin missile launcher adds more weight and drag, to a fighter that already suffers from overweight and lack of aerodynamic performance.

Name me contemporaries of Tejas which has an empty weight of 5500Kgs?

Just to help you. Some are as such.

AIDC F-CK-1 Ching-kuo's Empty weight: 6500 Kgs

Gripen C/D's Empty weight: 6800 Kgs

F/A-50 GE's Empty weight 6470 Kgs

FC-1's Empty weight 6586 Kgs

Note: Tejas has a far chubbier fuselage than it's contemporaries.

Overambitious ASRs, GSQRs and NSR(well not so much unlike other two sisters) have been a major hindrance in defence modernisations. Case in point is Army Multi-cal AR trials etc.

That's why the only solution as explained ealier remains, to either add CFTs and free the inner wing stations from fuel tanks, for the use of weapons, or add additional hardpoints, which however requires a re-design of the wings or gear bay / centerline station, by the lack of space.

Check the pic posted above, with a microscope may be. ..........Again you are proven wrong by ADA. ROFL!

Lol of course not! I don't claim things that I didn't looked up first, to get a basic understanding. :biggrin2:

Yeah that expert understading of yours which says A srtike missions requries 2x Drop tanks on innerboard always. Check pic again. HAHAHA

And again, no informing => lack of understanding => claiming baseless things...

MK84 dumb bomb:
Weight 2039 lb (925 kg)
Length 129 in (3280 mm)


GBU 31 (MK84 dumb bomb + JDAM kit):
Length: (JDAM and warhead) GBU-31 (v) 2/B: 152.7 inches (387.9 centimeters); GBU-31 (v) 4/B: 148.6 inches (377.4 centimeters)
Weight: (JDAM and warhead) GBU-31 (v) 2/B: 2,036 pounds (925.4 kilograms); GBU-31 (v) 4/B: 2,115 pounds (961.4 kilograms);
http://www.navy.mil/navydata/fact_display.asp?cid=2100&tid=400&ct=2

So no matter if you take LGB or sat guidance kits, to convert dumb bombs into smart bombs, the size will increase. That's why your old wind tunnel model and Jag dumb bomb loads have no meaning for LCA or modern warfare.

Lack of comprehension skills often makes one more stupid than he is already.

My line was this

"Here in this case, the overall length of bomb does not increase much"

It was said in context of LGB vs Dumb Bombs with only tail kits. A JADM is only a tail kit (and midbody stakes) bolted on an iron bomb. And yes it does not increase length as much an LGB does.

So here it is left to be seen if those tandem bomb rack pylons on Tejas's inner-board have enough flexibility to handle 20-30 extra inches or not. Since they are testing that configuration in this present time i believe they are made with enough flexiblity to meet preset day requirements.

Still for a moment i assume they are not flexible enough for 500-pound bombs with SAT. kit, they definitely for smaller size bombs say 250 pound.

Just to give an idea Even a Mirage 2000 with 9 stations has to give one station for mounting a targeting pod in multirole configuration. Which leaves it with just 1 extra station over Tejas-MK1 in said configuration.

So the logic stands true again. For its size Tejas has a sufficient number of stations.

Yes now that I explained it to you and by providing you the link to Dassault. Your welcome.

Back taracking after being proven worog. Well you are most welcome.

Anyway just to fill your ignorant head. Multi-role stands true for both PR tags called Omni role and Swing Role which were coined by Rafale and EFT respectively.

Wrong, since the FCS doesn't limit the load capability of the fighter, but to switch from 1 role to another, the key is to be able to carry the necessary loads at the same time.

Multi role example:
An LCA is sent for a strike mission and as shown by ADA mission configs, can't carry BVR missiles, so it has to return to base, re-arm for CAP and refuel to switch roles.

Swing role example:
An MKI on the other hand, can do the same strike, remains loaded with at least 2 x BVR + 2 x WVR missiles and only needs IFR to switch to CAP in the same sortie!

Your 'Lahori Logic' does not stands any ground (never it was). Not wasting my time again.

Swing Role is different from Multi-Role. Even 'Heavens' are laughing.

 

[HariPrasad-1]

But what's interesting is that, the CFD constraints i.e. Since the canopy was reshaped a bit, the constraints of either having more space at the back of the pilot seat or not will affect the flight dynamics or not.

They have planned this space to add 60 KG fuel which perhaps will help to eliminate dead weight. Drag reduction should also boost the ferry range. In comparative study with F 16, VIvek Ahuja had observed that any reduction in weight of tejas from current level shall result in a great boost in performance of aircraft.

Contemporaries of Tejas

AIDC F-CK-1 Ching-kuo's Empty weight: 6500 Kgs

Gripen C/D's Empty weight: 6800 Kgs

F/A-50 GE's Empty weight 6470 Kgs

FC-1's Empty weight 6586 Kgs

Note: Tejas has a far chubbier fuselage than it's contemporaries.

Empty weights of Contemporary AJTs and CATs.

BAE HAWK 128: 4480 kgs

Hongdu L-15 Falcon: 6500 kgs

YAK-130 : 4600 kgs



Somehow Tejas shall weigh as low as 5500kgs?

Wing Co.(retd) Uni Pillai had rightly said "Users should avoid preparing QRs based on best features seen on different platforms".

 

[HariPrasad-1]

The Chinese media thinks with the integration of advanced AESA radar (RBE 2) ,EW Suits and other proposed modifications, the future versions of Tejas will be "A Single Engine Rafale"!

Don't be exited yet, conditions , when all the proposed modifications are implemented , only then future Tejas will be what can be called a perfect advanced fourth generation aircraft capable to complement Rafales in IAF.

In several interviews or analysis by experts etc many experts have said that Tejas Mk 2 in terms of payload will be something like Mirage-2000 and capability like Gripen.
https://www.facebook.com/pg/TeamINDRA/photos/?ref=page_internal

When Dry thrust increases, MTOW also increase and that gives the plane capability to carry higher payload. When GE 414 is coming with 62 kg dry thrust, This should give tejas MTOW 15.5 tons which is higher by 2000 kg. Mk2 is supposed to be lighter but evenif the empty weight remains 6.5 tons, it should carry 2 ton additional payload. If I consider 1 ton additional fuel (Planned in mk2), it should carry one ton additional payload which turns out to be 5 tons which is very decent. Range should atleast increased to 2400 KM. Here people may argue that GE 414 shall consume more fuel but It shall be only a marginal higher consumption if at all it increase. On other hand aerodynamic improvement shall have a big positive effect on fuel efficiency and acceleration. So yes, it shall be a very potent aircraft and if we put electronics right (Like in case of (Mirage upg), it will become a mini rafale. This plane should release many twine engine aircraft from many missions. It will be a big big saving.

8 aircrafts already delivered one will be delivered at the month end. I think this journalist yesterday woke up from his 3 month long coma...
