These forges will probably manufacture parts for GE engines. Will likely benefit the Kaveri engine as well.
HAL has been placing orders for the long lead items ever since aon granted without waiting for final contract award, one due to aerospace market experiencing slowdown and only trying to recover and also to improve their delivery schedule. The 240 al31fp and 80 rd33 all are the same as before spec, only type approved replacement lru in case of obsolete one or unavailable one is to change. Entire supply chain and operating circle is tuned to it, now if you change or upgrade you need to build that circle again, multi year job.
Why do they want to test it on a fighter jet directly? Why not a flying testbed?
IISc-Bengaluru develops indigenous fuel injector for fighter planes, to be tested on AMCA

Researchers at the Indian Institute of Science (IISc) have developed a new high performance fuel injector system for fighter aircraft. The injector, designed using 3D printing, produces exceptionally small fuel droplets for efficient combustion. Tested successfully under various conditions, the injector surpasses existing technologies and is slated for use in India's AMCA.

BENGALURU: Researchers at the Indian Institute of Science (IISc) achieved a significant breakthrough in aerospace technology by developing a next-generation high-performance fuel injector system for fighter aircraft. It is slated for implementation in Advanced Medium Combat Aircraft (Amca), India’s fifth-generation single-seater fighter jet.
“We’ve developed a new high-performance, high-shear swirl injector. It produces exceptionally small droplets, crucial for efficient fuel-air mixing and complete combustion,” Prof Saptarshi Basu, the lead investigator of the project, told TOI.
The innovative technology, developed as part of a Defence Research and Development Organisation (DRDO) Centre of Excellence for Propulsion Technology (CoPT) programme, represents a complete indigenous solution from design to testing. Basu’s team, which includes SK Thirumalaikumaran and Sonu Kumar, worked with DRDO’s Gas Turbine Research Establishment (GTRE).
“The high-shear fuel injector, developed through advanced 3D printing techniques, demonstrated superior performance compared to existing commercial alternatives across all key parameters, including droplet sizing, spray pattern formation, flame stability, and flow field consistency,” Basu said.
The comprehensive development process involved multiple stages of testing and validation using world-class experimental facilities at IISc. “This achievement represents a perfect marriage between fundamental fluid mechanics research and practical applications in aerospace technology. Our team utilised a sophisticated experimental facility capable of handling air supply up to 40 bar and maximum flow rates of 6 kg/second, enabling thorough testing of the injector’s capabilities,” Basu said.
Basu, while pointing out that a final schedule for when it will be tested on AMCA — which is still under development — said that the injector also has the potential to be used in civil aircraft with minimal modifications.
“The development process encompassed multiple technological achievements, including the creation of a high-pressure optically accessible test facility operating at up to 15 bar and advanced flow visualization using simultaneous high-speed PIV [or Particle Image Velocimetry, an optical method of flow visualization] diagnostics,” Basu said.
The team conducted comprehensive testing under various pressure conditions with both gas and liquid fuels, consistently demonstrating the injector’s superior performance over existing solutions.
The project, Basu said, not only yielded multiple scientific papers and patents but also served as a valuable training ground for several students in advanced aerospace technology. “The successful development received high praise during the CoPT review, marking it as a significant milestone in India’s journey toward self-reliance in critical defence technologies. Technical results revealed optimal measurements at different air-to-liquid ratios, confirming the injector's exceptional performance,” Basu said.

ATDG is ATGG actually, advanced turbo gas generator engine which Azad Engg is making end to end.
GTRE has held a felicitation event for Laxmi Machine Works Pvt. Ltd. The company has worked with GTRE to productionize the gearbox of Kaveri engine. The company currently produced the gear boxes for the Su-30'MKIs Al-31FP engine.
I believe with the BrahMos aerospace afterburner, we will definitely have a working engine soon. A few more tweaks are needed to reduce the weight. If possible around 100 kg will be good enough. After the successful Manik engine fabrication, I think BrahMos Aerospace is proving its capabilities in aero engine fabrication. HAL should use these engines for HLFT-42.
The changes/design modification come from GTRE, BATL executes it as per spec, I think they still also have to certify the QA with GTRE nominated inspection agency for every stage inspection & QA check. What I mean here is its not entirely their free hand work where you can use your own expertise and make suitable design/spec changes as needed. So how much improvement can be expected ?
Lack of actual details on kaveri imo hints at it being in a standstill sort of situation. Lets see the dry version first, how it works on the ucav platform, trails etc.
