HAL Hindustan Lead in Fighter Trainer (HLFT-42) Trainer Aircraft Program

What ? The Al-31 has a dry thrust of ~ 75 KN & a wet thrust of ~ 125 KN . That's a medium weight fighter whereas HLFT is a LIFT / Light Fighter. What's he on about ?
Russians on proposed S54/55, basically a single engine Su30MKI to be used as a light combat aircraft in India and a replacement for L39 jet trainer in Russia.

That was sub 10 ton design. HLFT is near 15 tons.

In the current config, you will need 70+kN of thrust.

Then it's neither a LIFT nor a Light Fighter which was the whole idea behind the project . It's heavier than the LCA . What's the point in developing it then ? How will it compare to similar offerings by RoK & Italy ? Both these countries have notched up good sales not to mention China & Russia which have their own products which are equally competitive even if we ignore the Russians .

Personally I am not in favour of this. I would rather want HAL/ADA to focus on a jet trainer which can go supersonic using dry kaveri to replace HAWKs in future.
 
This is just a waste of time and energy. Why would you need such a powerful engine for a trainer? Are you going to compete with the LCA Mk2? Do they know about T-7 Redhawk or Hurjet?

They should design the trainer around the 75-81Kn Kaveri. It will strongly support the case for funding the continued development of Kaveri.

But, maybe its too much to expect anything rational from Govt or DPSUs.

There's no MoU between DRDO (ADA) and HAL (ARDC) till date. That's why illogical duplication of efforts.
 
Why do you need ADA for a trainer? Where is the duplication?
DRDO has well developed mission computers and flight control systems in place. By not having an MoU HAL has no access to them. HAL has to reinvent the wheel from scratch for their projects.

Same for DRDO, while HAL engine division holds all the ToT (whatever level it might be of) of Adour, RD33, AL31FP etc, GTRE had to start from scratch.

Criminal duplication.

Why would they not take already developed systems? They don't even have to go to DRDO. They just have to get it from a production partner. You dont need MoU for that. That too a non funded/existing design.

HAL holds manufacturing ToT, its not very useful for GTRE. Every indian engine development will have to start from scratch. Its just bad understanding what a ToT is.

Leave the electronics. The situation is so bad that HAL doesn't even uses Chitradurga.

It does it's testing from HAL airport which has the extremely busy bangalore airspace. This means that the envelope for flight testing is severely limited.

The Chinese reverse engineered AL31 from blueprints meant for servicing the engines.

You do not have the right understanding of engineering and management if you are overlooking these factors.

There is no need to use Chitradurga for HAL products as of now. Their airport is good enough, airspace is not busy as the civil airport outside the city.

Barking up the wrong tree.

Lol, you though ToT is enough to develop new engines and telling other about engineering. cool.

The airspace is extremely busy. Open any transponder tracker and view for yourself.

The optionally manned tests on Kiran were being conducted from HAL airport over populated areas. You cannot validate the whole system without risking the lives of people there.

Your ignorance is not my concern. The ToT received by HAL for manufacturing of AL31 and Radar of Su30MKI could have accelerated any development program by more than a decade.
