LCA TEJAS MK1 & MK1A: News and Discussion

[BON PLAN]

Nope J10 is still not upto the mark, LCA has far better design with canards/levcons in Mk2 it will lead the race

LCA mk2 is a paper project so far. J10 is a reality, and seems in acrobatic show quite pretty.

 

[BON PLAN]

Its more difficult to perform without canards.. also having canards increases the radar profile. ..
Your third generation fighter J-20 has canards.. Guess, your lousy engineers found it hard to manage without canards..

Canards increase RCS : Yes. As a tail in the F16 case for exemple...
To perform without canards with the same perf is indeed harder. But I'm afraid the perf are inferior.

Do you know what is China's first aircraft with cranked delta wings? J7P
View attachment 99904
If you are talking about him, I bet you won’t be able to design it in eight years, even if you give it to the Americans.
It completely changed the aerodynamic layout and flight control system of LCA, which is completely another kind of aircraft

What is "cranked delta wings"?

 

[The Shrike]

Which one of those will you use in F5 standard?

Please deposit 2 billion euro in development charges first .

Sorry I don't get, it what is "crank" here in the image, can you explain, thanks.

These two are more dissimilar that TEDBF is compared to Rafale

ie the delta leading edge is not straight from the beginning to the end.

 

[BON PLAN]

My personnal choice is.... Su30 ....

Kudos to the men who made this dream of true blue indian made 4.5th gen fighter a roaring success of a reality

Reality: yes. In spite of decades of problems, a Tejas good enough to be useful as a light fighter is a reality. Roaring success of a reality: very questionable. The reality is that with a production setup capable of producing 4 frames a year since 2011 (I think), then later 8 - call it 60 frames possible production over the last 10 years - less than 25 have been built.

Let's see what happens with FOC production. 16 complete, working FOC are supposed to be delivered by end March 22.

Bharat's obsession with tejas results from that of GNat and it's Bharatiya derivative ajeet.
The air force , got it's first taste of a agile point defence fighter with the induction of the Nat in 60s .
Thus tejas.

Let me probably talk about the origin of the J10 design. What China first wanted was a light interceptor to intercept the Soviet tu22m bomber group, named J13, using WS6 engines, but due to China’s financial difficulties and technical difficulties, China was Forced to stop the development of J13,
Next J10
First of all, J10 is required to have better interception performance, so J-10 is required to have better supersonic performance
Compare J10 and LAVI,
J10 uses a baffle inlet, while Israel uses a Pitot tube inlet similar to F16, which is similar to F16 and pays more attention to subsonic performance
Next, the vertical tail, the vertical tail of the J10, and the vertical tail of the J-10 are very large, which is good for supersonic maneuverability.
Next, the most important canard, the coupling distance of the J10 canard is longer than that of the LAVI. It pays more attention to the effect of the canard to increase the lift, and the supersonic performance is better
For the main wing, China uses a delta wing, while Ravi uses a swept wing.

I mean J-10 penalty superior to La'vi in almost every aspect... & in turn can be directed to outperform the legacy F-16, Mig-29 & Mirage-2000..

This news is not got for its at all (although only 36) & definitely not enough to counterbalance Rafales.

Bleh ji we people make an assumption that China will look at money while handing weapons to Pak , they will to some extent but will give some leeway as it concerns India .
I think China will give more than 36 j 10 to Pakistan.
A second front should be strong against us , you see

You can explain all that you want : it is well known that the lavi drawings came in the chinese hands.
The chinese modified the drawings so as to cope better to their needs (maybe with some israelis helps... but it's not sure), and as the plane is bigger needs a greater vertical fin. The air intake use globally the same design. It's only the last J10 that used a DSI like intake.
Less coupled canards than in Lavi design : Yes, to be a better interceptor when Lavi's job was mainly air to ground.

Rafale design is very brilliant


Rafale made the following improvements on the basis of the close-coupled canard.
1
Reasonably layout the overall size. In order to reduce the height of the whole machine, Rafale did not use the real belly air intake, but adopted a similar two-rib air intake, which can maintain the advantages of the belly air intake in the case of high angle of attack and large deflection angle. Because the abdomen intake can ensure the air flow rate for the normal operation of the engine, and can effectively reduce the height of the whole machine.
2
Reduce the size of the nose, Rafale's RBE2 passive phased array radar has a diameter of only 535mm, and the nose is reduced, and the rear fuselage is also easy to shrink. Of course, this has advantages and disadvantages, and subsequent radar models will inevitably limit their performance due to the limitation of the caliber.
3
It is to reduce the area of the canard, supplemented by the small side strip wing, improve the vortex and increase the lift effect. In fact, the canard wing + side strip wing is not the original J20, nor is it the original gust. The earliest originator of the mountain is the prototype EAP of Typhoon. It set a record for choosing mid-to-long distance coupled canard + side strip + double delta wing,
Canard + side strip + double delta wing, high-speed performance is excellent, low-speed performance is also very good, but this is a disaster for the flight control system, and Rafale selected close coupling + small side strips, while reducing the canard and main wing With a large delta wing, the lift coefficient of gusts, low altitude maneuverability (wing load), and high angle of attack maneuverability are very good. A simple small comparison, FA18 has spent countless efforts for low-speed performance, its landing speed is 232KM/H, and the gust corresponding to 213KM/H.

Generally speaking, China has introduced fly-by-wire flight controllers from Israel (some say it was imported from France), and the introduction of PL8 has a great impact on China.
