LCA Tejas vs JF-17 Thunder

[Vijyes]

Well even with that it will not be a 70% jump in range. External drop tanks increases drag on air frame also it increases the weight of fighter so the mileage reduces a lot. Most of the cases I know it that combat radius cannot be increased more 20% with help of external fuel.


Well that depends if the fighter is Rafale or F-15 external tanks can be consider even with upto 5 tons fuel because the fighter have 9-10 tone load capacity and the fighter will be still carrying 4-5 tons bomb load easily and this will increase 20% combat radius. JF-17 where Tejas it will be at 1 ton for JF-17 as it should be carrying at least 2 tons of load. For tejas it can be upto 1.5 tons external fuel.

Just because the fighter has payload capacity doesn't mean it can carry any number of payload. The external tanks take the hardpoints. There are limited number of hardpoints. Also, imbalanced loading will create aerodynamic problems

JF-17 have 3400 KM range is a pure lie. As far as I know this figure is impossible on internal fuel for most of the top fighter including Rafale, EFT, F-22, F-16, Gripen, and many more.

JFT is a 6.6 ton fighter with 2.3 ton internal fuel so it's loaded weight should be somewhere 9.3 tons. The fighter have only less then 25% fuel when having no external load. It's range should not be more then 2000 KMs with that.
And as we know it's maximum takeoff weight is 12.5 tons which roughly allows it to carry only 3 tons of load it should be not possible for the fighter to go 3400 KMs with 3 tons external fuel too.

no its not a lie ............. the pilot pushes it all the way !!!!

Tejas is a little outdated. Ferry range and weight carried for bombs/ missiles is less than jf17. Ferry is less than half as compared to f16. I think delta wing was not a good idea. Creates more drag hence less range.

Tejas has payload greater than Jf17 on ioc 2 standards only, why so Derby I and pythonV is outdated against Chinese Pl12 and Chinese wvr, when did jf17 fired smart weapons, and range varies with the mission type, any light fighter which stated with 1350km of combat radius is impossible with 2300kgees of fuel and 3 drop tanks in mixed mission which includes, Intercepting, bombing and air Superiority.

Tejas Crude specs are nearly same as mig 21. Tejas is certainly better than mig 21 but world has moved on. We have built something and we need to build on the experience. India cannot take on two front war on borrowed wings.

Lol not the same, Mig21 is highly modified to bis yet don't match the specs with its outdated radar and needles in cockpit.

hey ...why we r comparing Tejas with f16 and gripen.....it's wrong na

first time we hv made something...next time we will make the best.

Hal is learning .....

and iaf had just given a rough comparison to convince goi...
my heart broke in to. pieces after reading that news ..from India today. I am a Tejas lover

IMHO, Tejas MK1 are more modern than Upgraded MIR-2000, Comparing them to MIG-21+++ is futile, If some shameless people have said MIG-21 is better than Tejas in some parameters then i bet Red barron triplane too has some advantages over top notch F-22 ..

But again for the knowledge, Here a fruitless comparison =========== >>

Full Glass Cockpit: No (1HUD+1MFD+limited HOTAS+HMCS)
LCA: Yes (3MFD, HUD, full HOTAS, Helmet Mounted Display - better than cueing sight)

LCA -far more modern ejection seat, the Martin Baker Mk16 as compared to that on the Bison which is the KM-1M, one that is unchanged from the Bis.

Radar: Bison - Kopyo (range limited to 57Km for 5SqMtr, limited scan angles thanks to Bison nose)
LCA: Hybrid MMR - 100 plus Km for a 5 sq meter target, wide variety of modes, scan angles of the order of 60 degrees

EW suite: Bison - Tarang MK1, external jammer which if carried, reduces number of pylons (already limited to 5, by 1)
LCA: Integrated internal suite, with both RWR & jamming capability

Litening pod for the LCA; not on the Bison

Propulsion: LCA - modern more reliable powerplant with FADEC
Bison: Older gen powerplant, no FADEC, issues with reliability and maintenance

LCA: FBW for carefree handling and pilot friendlyness; has FBW dictate maneuvering limits with loads, stores, and other criteria preventing errors
Bison: No

LCA: Special measures for reduced signature in design itself - canopy, airframe, use of specific materials, Y shaped intakes displaced for signature reduction
Bison: Original MiG-21 design, only RAM possible, comes with weight penalty, important as weapons add radar signature

LCA: Able to carry dedicated LDP/Special store on dedicated pylon
Bison: No

LCA: Has 7+1 pylons per design
Bison: 4+1, limiting flexibility

Payload: Edge to LCA even using 6400 Kg empty aircraft weight (~900 kg over original 5.5T) and 10.5T, empty weight with 2R73E missiles included. Has payload of 2.5T for 5 remaining pylons

Growth potential: Edge to LCA - items such as Oxygen generating equipment being included, plus In Flight Refuelling

Stores flexibility: LCA has 1760 standard avionics fit allowing for western, Indian, Russian weapons
Bison: No

Avionics: LCA has provision for datalink, has modern avionics, computers etc
Bison: Limited upgrade, few of these are included in current aircraft

Systems: LCA designed around test kits, with simulators for crew
Bison: Limited by original MiG-21 design, only part task training

Combat Radius : Tejas +500Kms, Bision limited to under 300kms ..

---

With 7 pylons and more fuel capability + even disregarding IFR on the way, its a joke to say LCA == MiG-21 as some folks have been pushing on ..

Lol not the same, Mig21 is highly modified to bis yet don't match the specs with its outdated radar and needles in cockpit.

Do not compare lite fighter F-16 (up to 20 tons MTOW, 1 12-15 tons engine) to ultra-lite Tejas (up to 15 tons MTOW, 1 8-10 tons engine), they are in different classes and weight categories.

LCA Tejas May Not be The Best But It's More Superior Than Pakistan's JF-17
Monday, November 13, 2017 By: India.com Source Link: CLICK HERE


According to reports, the armed forces are not in favour of proposed versions of indigenous advanced versions of Tejas, light combat jet, and main battle tank Arjun. The Indian Air Force is yet to give final operation clearance to Tejas, which has been in the development mode since almost 30 years.

In July, the IAF inducted the first squadron of home-grown Tejas with two fighter planes joining the force. The squadron named – Flying Daggers 45 – is expected to have its full strength by 2018-2020. However, the IAF is not eager to expand its Tejas unit.

The IAF has raised questions over several limitations that the Tejas has. The fighter jet’s limited range and weapon carrying capacity are on top of concerns that the force has pointed out.

Despite the limitations, the single-engine supersonic jet is far more capable than JF-17 Thunder, the combat jet developed jointly by Pakistan and China. As far as technical specifications are concerned Tejas is way ahead of JF-17 Thunder.


Tejas vs TF-17 Thunder ::

1. The developers at at Hindustan Aeronautics Limited (HAL) used IAF’s trusted Mirage 2000 as benchmark while developing Tejas. The IAF wants to replace its ageing fleet of MiG-21s and Tejas was considered to fill in the gap.

2. The fly-by-wire technology in Tejas makes it easier for the pilot to manoeuvre the jet while in war mode. The fighter jet can also carry air-to-air, air-to-surface and laser-guided missiles.

3. The HAL has fitted Tejas with advanced Israeli radars which is considered to be one of the best in the world. The early warning radar system, which works to alert the pilot of any incoming threat – enemy aircraft or anti-aircraft missile – is developed indigenously.

4. What makes Tejas an agile bird in the air is its frame. Developers have used carbon fibre in its fuselage which reduces the weight of Tejas. It also helps the fighter jet to absorb enemy radar waves thus adding to its stealth capabilities.
5. The height of Tejas 4.40 metres and its length is 13.20 metres. The wingspan of country’s own combat jet stands at 8.2 metres.

6. While JF-17 needs to touchdown every time it needs to refuel, Tejas has the mid-air refuelling facility.

7. Apart from the mid-air refuelling capability, Tejas has bigger fuel tank that JF-17 which means it can operate for a longer period. The capacity of internal fuel tank of Tejas is 2458 kg. In JF-17, it is 2268 kg.

8. Tejas needs a runway of as short as 460 metres. On the other hand, the JF-17 requires a minimum 600-metre-long tarmac to take flight.

9. Tejas can operate up to a height of 50,000 and can cruise at a top speed of 1350 kmph.

10. The glass cockpit of Tejas enables the pilot to read even the minutest of details. The real-time information displayed right in front of his eyes is of great help.


The idea for an indigenous fighter aircraft was conceptualised in the 1970s, but actual work on the aircraft project started only in the 1980s. The aircraft was named ‘Tejas’ (meaning radiance in Sanskrit) by former Prime Minister Atal Bihari Vajpayee.

Do we really need to say this, Jf 17 seriously? Dont insult India with such comparisons. If we must f16 or gripen should be benchmarks. Kill se fighter competition non sense.

 

[Kshithij]

There will be long campaign against Tejas across media. But no one will care. People will only get angry at Modi if he doesn't clarify that Tejas will be inducted and all these stories are nonsense

Modi doesn't have to put his finger in every matter, in fact adding Modi to picture will worsen the situation. (2015 elections is best example)

Let the bitches moan(I can't say let the dogs bark as it would insult dog's loyalty)...let the HAL build, Let ADA progress(for FOC)...Soon we'll have the squadron and more of Tejas while rumors die down.
