Tejas to take part in international air combat excercise... 😍😍😍
This is a very good News it shows that Tejas is now mature to take on what ever porkies throw at us... 😊😊
This should generate more sales than all the air shows it participates in.



Is EurasianTimes credible or IDRW by another name?

A 100 KN Safran engine MII for Tejas?


Given the growing defense collaboration between the two nations, Jaishankar may hold negotiations with the French government about the transfer of technology to produce 100-kilonewton Safran aircraft engines in India as part of the ‘Aatmanirbhar Bharat’ (self-reliant India) program.

The engine development agreements between the two countries have been ongoing for quite some time. Indian Defense Minister Rajnath Singh said in December last year that France has agreed to jointly produce aircraft engines in India to increase the country’s self-reliance in the defense manufacturing sector.

“A big French company will manufacture an engine in India, thus far not made in the country, in collaboration with an Indian firm,” Rajnath Singh then said, most presumably referring to the Safran group.

France had earlier also proposed an enticing proposal to revive plans to develop the indigenous Kaveri jet engine as part of the Rafale agreement, as previously reported by The EurAsian Times. In addition, a detailed presentation on developing an aircraft engine ecosystem in India was given.

Safran, which develops engines and electronics for the Rafale fighter, has offered to co-develop the Kaveri engine for the Indian Light Combat Aircraft (LCA) program, which currently relies on GE engines.

Rajnath Singh stated that the Indian defense and aerospace industry market, which is currently around $85,000 crore, would grow to $1 lakh crore in 2022 and $5 lakh crore by 2047.

In early 2021, Hindustan Aeronautics Limited (HAL), India’s state-owned aircraft maker, and Safran signed an MoU (Memorandum of Understanding), announcing their intention to collaborate on bringing niche engine technology to India.

France had indicated that India will be the sole country to get such advanced technology transfer, ensuring that New Delhi would achieve complete “sovereignty” in the field of aero-engine technology.

Very nice news indeed!
The ground attack capabilities of Tejas was reported to be better than other platforms from the last Vayushakthi. Are their any such reports regarding its air-to-air combat capabilities?

Eurasian times is the most sold out paper, they publish every country's propaganda without discrimination. One day, tejas is bestt in the world, next day JF17 is best. One day J 20 is 4th gen fighter, and next day US will lose a war with china. Full propaganda site for all sides.

for folks who complain about drag in tejas,

this F16 Vs F16 XL article is a good read,

which explains the all crucial high G onset rate of double deltas (cranked delta in tejas) , which holds the key in modern close combat specs


from the article above

"
Importance of High Turn Rate

For a decade and a half, many fighter tacticians have stressed the paramount importance of being able to sustain a high turn rate at high Gs.

The rationale was that with such a capability, enemy aircraft that cannot equal or better the sustained turn rate at high Gs could not get off a killing shot with guns or missiles.

With developments in missiles that can engage at all aspects, and as a result of having evaluated Israeli successes in combat, the tacticians are now leaning toward the driving need for quick, high-G turns to get a “first-shot, quick-kill” capability before the adversary is able to launch his missiles.

This the F-16XL can do. Harry Hillaker says it can attain five Gs in 0.8 seconds, on the way to nine Gs in just a bit more time. That’s half the time required for the F-16A, which in turn is less than half the time required for the F-4. The speed loss to achieve five Gs is likewise half that of the F-16A.

All of these apparent miracles seem to violate the laws of aerodynamics by achieving greater range, payload, maneuverability, and survivability. Instead, they are achieved by inspired design, much wind-tunnel testing of shapes, exploitation of advanced technologies, and freedom from the normal contract constraints.

The inspired design mates a “cranked-arrow” wing to a fifty-six inch longer fuselage.

The cranked-arrow design retains the advantages of delta wings for high-speed flight, but overcomes all of the disadvantages by having its aft portion less highly swept than the forward section. It thus retains excellent low-speed characteristics and minimizes the trim drag penalties of a tailless delta.

Although the wing area is more than double that of the standard F-16 (633square feet vs. 300 square feet), the drag is actually reduced.


The skin friction drag that is a function of the increased wetted (skin surface) area is increased,

but the other components of drag (wave, interference, and trim) that are a function of the configuration shape and arrangement are lower so that the “clean airplane” drag is slightly lower during level flight

, and forty percent lower when bombs and missiles are added.

And although the thrust-to-weight (T/W) ratio is lower due to the increased weight, the excess thrust is greater because the drag is lower – and excess thrust is what counts.

The larger yet more efficient wing provides a larger area for external stores carriage. At the same time, the wing’s internal volume and the lengthened fuselage enable the XL to carry more than eighty percent more fuel internally. That permits an advantageous trade off between weapons carried and external fuel tanks."



good read

What could be the probable route will be taken for the LCA Tejas to reach United Kingdom?
Will it be India-Oman-Saudi-France-UK? with Pit stop in Oman or Saudi.

I wrote a 20 page article one year back and posted on DFI. Using studies from F-16XL the aerodynamic drag for Delta wing is lesser compared to conventional swept back wing even though area of Delta is larger. Hence LCA has very good acceleration and range. It’s payload range matrix is better than Jaguar and almost near Mirage 2000
any PDF or link?

I don’t know if this is just me, but did anyone in this thread also had a hard time differentiating Tejas FOC standard and Mk1A? Thanks to other forums that I joined, I learned that while both are good and modern light fighter-interceptors, the latter is designed and deemed to be a lot more versatile. However, since Tejas FOC often gets better updates through the several variants released over the years, I think that sooner or later it will be a more preferred option than Mk1A. Take Tejas Mark-1A, for example. Tejas Mark-1A, the latest variant of the Light Combat Aircraft, will have several enhancements over the Mark-1 model to boost performance and maintainability. I have also heard about the HAL Tejas, and I find it interesting that it began in the 1980s to replace India’s ageing MiG-21 fighters but instead later became part of the general fleet modernisation policy.

Because they kept tweaking the Mark2 till 2018... Mark1A was suggested by HAL an interim stopgap.

Main differences are replacement of foreign components by indian aesa radar, quartz radome, jammers, dual-rack for CCM etc. to get indigenous content from 70% to 90+%. Only the engine & ejection seat will be imported.
They're also streamlining the LRUs to make it more maintenance friendly.

That's it.. Other than that there's not much difference. No design change, no weight reduction.
