Got the kN device to do a little dance today!

Ran it at ~75% throttle—stable, responsive, and sounding better with every test. Tuning's paying off! pic.twitter.com/EN1ztI36FU

GD Jetcat India showcased their turbo-engines in AeroIndia. This is the Indian division of the German parent company:
This engine below is the same Vedaa Aeronautics engine ?
Saw this beautiful 3kg jet engine capable of producing 42kg thrust. Wanted to buy it until I heard the price tag of 16L. 70-80% parts are indegenised with the main compressor still being Czech IP. Sales guy explained difficulties in producing sustained thrust past 800 celcius pic.twitter.com/LVugonGVA0

From what I understand Veda Aeronautics' primary interest/expertise is in loitering munition. They had to indigenize this engine for their LM. This is why Kalyani-Veda Aeronautics deal is win-win.
With Kalyani's help Veda can further indigenize their sub 100 Kgf turbojets. When they make LM's that would need 120-400 Kgf turbojet engines they can easily access Kalyani's portfolio.
Excited to announce that DG Propulsion has signed a Strategic Agreement with Bharat Dynamics Limited (BDL) to collaborate on jet turbine engines for loitering munitions, high-speed UAVs, and advanced propulsion systems.

A big step toward strengthening India's defense…
The kN device ran full tilt for 30 minutes straight—no breaks, no hiccups.

The more we test, the more data we collect, and the better our engines get.
Testing nahi rukni chahiye. pic.twitter.com/Sva33PHiNA
These engines will be flying soon, and when they do, the impact will be clear.

No Plan B, just absolute reliability and de-risking for our customers, partners, and the nation. We stand behind our hardware—no matter how much testing it takes.
Latest test runs—throttle control… pic.twitter.com/eg7zFsRnPk
We have any more info on the PBS India made engines status ? they seem to take part in recent expos but hardly seen much mention

Yes, they were participating in one of those seminars. They have started some licence production if I remember correctly.We have any more info on the PBS India made engines status ? they seem to take part in recent expos but hardly seen much mention

Well I know very little about this stuff , here RDE is rotating detonation engine presented by Dr V Ramanujachari. This is actually IIT Madras work, tested at drdl. cc @Gautam @Ashwin @Rajput Lion
Once we master this tech, it's going to revolutionize our Space & Defense sector(jet engines, missile et al). Very nice find

Recently they announced successful development of a complete missile engine and solid booster system pic.twitter.com/bjYx38BcF2
^^ They seem to have made precision machined parts of some RDE maybe as per their site, but did not see any indication of them making the actual engine itself. They are a precision mfg co mostly.
SiriNor tests electric jet engine in India

SiriNor has successfully tested what it claims is the world’s first all-electric jet engine at its facility in Pune, India. The test on April 22 validated the engine at Technology Readiness Level 6 under NASA’s framework.
The Norwegian aerospace company with an Indian subsidiary reported that its engine prototype exceeded the design intent of 40,000 RPM and 10 kgf thrust as measured by a load cell during the ground test. The company sees this as a critical step toward full commercialization.
“This ground test is not just a technical milestone. It’s a moment of validation for our amazing team and our common vision,” said Ivar Aune, chairman and CEO of SiriNor.
The company is developing a tip-driven propulsion system using distributed edge-mounted motors rather than a hub-mounted engine. Built for thrusts ranging from 1kN to 90+ kN, the engine design aims to support ranges exceeding 4,000 km.
SiriNor is targeting UAV engine commercialization by mid-2026, followed by certification for larger platforms including ground-effect vehicles and aircraft.
The company has raised early-stage funding, reaching a US$20 million valuation following the successful test. SiriNor plans to raise another USD$5 million before the summer this year.
According to SiriNor, its engine architecture removes the need for combustion chambers and high-cost alloys, potentially cutting manufacturing costs by 30% and maintenance costs by up to 40% for aircraft engines. The power source-agnostic engine can work with both battery and hydrogen electric energy sources.
“Our engine architecture is designed for flexibility. It’s compatible with both battery and hydrogen electric energy sources, supports thrust ranges for everything from drones to commercial jets, and its simplicity brings unprecedented efficiency to aerospace manufacturing,” said Abhijeet Inamdar, co-founder of SiriNor and CEO of SiriNor India.
SiriNor said it has seven letters of intent with global drone, ground-effect vehicle, and small aircraft developers and operators. The company employs engineers from both Norway and India, with team members having previous experience at companies including Airbus, Tata Vistara, GE, Pratt & Whitney, and Equinor.
