That is a wrong assumption IMHO. Though the French behaves as if they have a very independent foreign policy, but USA can pressurize them into doing what is wants. Recent sanctions on Russia are a prime example. France and Germany did not want such fullscale sanctions, because they knew at the...

The downside of such rectangular nozzle is reduced thrust at the cost of reduced rear aspect RCS and IR signature. Thus, F-22 needed a more powerful engine to acheive the same kinematic performance of a typical 4.5 generation Su-27 (and its derivatives) which have round nozzles. It was always a...

Lavrov is coming in 2 days in Delhi. May be we can get some TOT on Item-17 engine for AMCA, taking advantage of the current situation?

Yes.

In the video, we can see at least 3 different versions of AMCA (with DSI) which can be distinguished with different geometry of their horizontal stabilator. I wonder which is the latest design.

At around 14:07 timestamp, Dr. Geodhare mentions these two aircrafts as stealth and non-stealth mode of AMCA. But top one features DSI intakes, whereas bottom one features conventional intakes with splitter plates.

Different AMCA design that what was showcased in Aero-India 2021.

Right now there is no 6th genration plane. USA's NGAD is under developement. But the question is how much more will it incorporate design changes over 5th generation plane. You see 4th generation planes airframe already had a very good level of manuverability. 5th genration incorpoarted...

The proposed JV engine of 110 kN is said to be upgradable by 20% thrust, which translates to around 130 kN. Thus incraesing the size of AMCA to similar to Su-30 mki seems logical, if it translates to improved fuel capacity and increased payload

Is TEDBF vertical fail fin and Tejas like delta wings compatible with stealth? Chinks have recently showcased a carrier compatible version of their J-31 with folded wings. The same can be acheived by Navalizing AMCA design. But the problem lies in its limited payload capabilities and unsuitable...

TF-X programme depends on foreign help on every stage. The Turks need Aerospace majors from EU and America for not only engine, avionics, missiles but also basic airframe designing. So the success/failure of TF-X programme depends on the effects of sanctions.

Today our aeronautical capabilities are mature such that we can handle 2-3 aircraft programme. In the next 5 years 4 new fighter jets prototypes will be developed and tested. The designs are optimized as per our service's specific requirement. So no need to join any foreign programme, which will...

Last year there were some reports in the media that L&T was to be likely chosen as a partner.

Similar to T-14 Armata pltform, Russia is not confident on PAK-FA platform. However, they desperately need a scapegoat who will induct these in large numbers, to recover the costs so that the Russian industry get the funds to develop the next analogous platforms. That is where India comes in...

In other words, if we deposit a ITO thin film on any existing fighter jet canopy (Su-30 mki, Tejas etc.), it will likely improve the radar wave scattering properties of the canopy, but it won't give them the golden tint.

The F22 Raptor canopy comprises two sheets of polycarbonate, sandwiched between two layers of optical glass, fusion bonded in an autoclave and drape formed over a canopy blank. Over that a thin film of ITO is used to incoming scatter EM waves. Hence optical properties of the canopy cannot be...

ITO is transparent in the visible spectrum not golden colored.

Both will have a maximum takeoff weight around 25-26 tons. However, unlike TEDBF there area on geometric area restriction on fuselage and wings on AMCA.

There is too much confusion on what ADA is propsing as the final design. Recently, one design came from DRDO Cheif's presentation, another design unveiled in Tarmak interview, another design in Aero India 2021. All of them is claimed the final design by DRDO.

In order to ramp up our production capacity, we need to involve private sector majors like L&T, Tatas, Kalyanis etc. Right now HAL is struggling to roll out 16 A/C per year, even after years of promising the same. This is despite the fact that major sub assemblies are delivered ahead of...
