The RCS reduction is compensated by the DSI in Thunder

That's wrong, DSI is a feature to improve the airflow to the engine and therefor to improve the engine performance. It is just a common misconception that it would hide the engine from radar waves and has something to do with RCS reduction, but it hasn't. JF17 has a Y-duct to do so, but that or the limited use of composites in Block 2 can't compensate the lack of RAM or coatings, which is the key feature to achive a lower RCS for any 4th gen fighter, be it for a newly developed, or an upgraded like the F16s, or Mig 29s.
That's where LCA has an advantage, since it was developed with a low RCS as a major aim and no matter what went wrong during the development, this field actually was pretty successful. The knowledge ADA, NAL, HAL and co. gathered wrt to designs, materials and coatings will be highly valuable for any future aircraft projects!

Hello Secur,

OT questions,
Can you tell me where is the JF17, Wing internal stamping panels, external skin panels, fuselage stamping, external skin, cockpit structure, tail piece stampings, external skins and canopies are being produced?

What is known to us , is that fifty-eight percent of JF-17 today is being produced at Kamra . The figure will rise to seventy-five percent by 2015 as per the reports . Now , knowing the Pakistanis , they never release that much info but what we assume that most of them are coming in knockdown kits from China .

Composites are a nightmare to service. Boeing 787 is a case in point. Aluminum is rugged and reliable. JF-17 is all that.

Fan boy hold your horse...as far as the Chinese are concerned they plan to induct the J-20 somewhere in 2019-20. Are they going to get some in the serial production specially for Pakistan in 2015??

J-20 serial production by 2015, IOC by 2017 when the first operational squadron is completed.

correction : Pakistan Aeronautical Complex (PAC) holds the exclusive rights of 58% of JF-17 airframe co-production work. not avionics, weapons etc

We also know that complete avionics are being produced at Kamra . If that were the case , they wouldn't have been talking about increasing the airframe co-production work to seventy-five % by 2015 .

Tejas empty weight 14,300 pounds. HAL Tejas - Wikipedia, the free encyclopedia

JF-17 empty weight 14,520 pounds. CAC/PAC JF-17 Thunder - Wikipedia, the free encyclopedia

F-35A empty weight 29,300 pounds. Lockheed Martin F-35 Lightning II - Wikipedia, the free encyclopedia

Granted, Tejas is lighter than JF-17 by a bit, but it's also quite a bit smaller.
JF-17's DSI bumps really hide the engine well. The bumps are huge.

Thinking that 58% of the parts of the plane are being produced at one plant is completely irrational and illogical. I do don't think anything is being produced in Pakistan for this plane.

's first operational plane equipped with DSI.
Tejas has already.. And Mind You dear. DSI is not everything, even F-22 is not equipped with DSI and that is still considered the best. DSI is just a cost effective solution to other

F-22 doesn't have DSI because it's a 1997 plane. F-35 does and it's a 2006 plane.

Aesthetics is a big part of selling. Cleanness sells. Ugly struts holding air intake to fuselage doesn't.

Aesthetics?Struts?Eh Fanboy??

 

[HariPrasad]

J-10B is in serial production, whereas Tejas still is not. What makes you sure Tejas can enter serial production when J-20 enters serial production in 2015? What radar does Tejas have?

recently there was an article of Chine media that J 20 has lots of design flows.

1) Design flow in weapon bay and fuselage
2) Faulty wing design
3) faulty design and lay out of engine
4) Non availability of Russian high thrust engine etc.

So J 20 is many years away than one would think.

Tejas, a game changer for Indian Air Force

Hyderabad, Dec. 27:
The induction of the Light Combat Aircraft, Tejas into the Indian Air Force will be a ‘game changer’ for the country’s air defence preparedness, says Avinash Chander, Scientific Adviser to the Defence Minister.
“Though delayed, the India developed fighter aircraft has emerged as a ‘contemporary aircraft’, as good or in a way better than the competitors in its class,” Avinash Chander told Business Line.
The LCA signals the country’s indigenous capability to develop a major air-based weapon platform and a step towards achieving self-reliance in aircraft design, fabrication and manufacture. It has laid a sound base for a smooth take off in the efforts to develop more advanced fighter aircraft in the future, Avinash Chander, Chief of the Defence Research and Development Organisation (DRDO), said.
The fighter aircraft, which obtained the Initial Operation Clearance on December 20, is a step away from induction into the IAF to replace the ageing MiG-21 aircraft. The immediate plan was to induct six squadrons of the IAF with the Tejas. This means about 120 aircraft. Already, the IAF has placed orders for two squadrons. Similarly, the Indian Navy will have atleast 40 of the naval version of the fighter aircraft.
In the next 10 years, atleast 200 LCA numbers are expected to bolster the country’s air strike power. The HAL, which will manufacture these aircraft, will provide 16 a year. It has built capacity and will further ramp up production facilities.
The DRDO Chief saw a Rs 1 lakh - crore opportunity in the next decade in the defence aircraft industry for the country.
The gradual induction of the LCA will ensure a forex saving to the tune of Rs 50,000 crore. In addition, the savings on life cycle and maintenance costs will be close to that figure in the long run, he explained.
There is tremendous scope for small and medium enterprises to make components and sub-systems and supply to HAL. It will also lead to creation of expertise and industrial infrastructure in the country.

Its just the matter of opening the envelop. IOC-1 approved 17. They made it from 17to 22 in IOC -2.

FOr IOC 2 it was 22* but they flew it to 24*. They target 28* in FOC the highest piratically useful limit.It will go beyond that also.

Hi Guys,

I show 2 awesome video of Tejas yesterday. In One video, tejas takes off fly some distance parallel to runway take sudden steep climb of almost vertical to some distance and takes 360*turns. In an another video, It climbs vertically, takes U turn, starts falling down and than take other horizontal turn within 9 seconds. These are some maneuvers which we used to see some very famous planes only. I was impressed to see Tejas doing that.

OK

It is on page No 145 of ADA Tejas IV on Indian defense analysis. I will do that within 2 days.

Hari,

Can u compare this to other fighters? Thx
