Successful flight test — another strong validation of the reliability and resilience of our engines. Jets belong in the air. And that’s where DG Propulsion engines are proving themselves.

We tested the relight firmware on our J100 turbojet engine by deliberately interrupting fuel supply to the pump, causing the engine to shut down. We performed multiple such tests to simulate fuel interruptions that can occur due to air bubbles in the fuel system or other reasons. The engine successfully relit every time, even after RPM dropped to as low as 2,000–3,000, which is quite low for an engine of this size.

Recent test of our DG J100 turbojet. Some serious thrust on display. It doesn’t get much better than this!

A new test cell. A new test stand. And another DG engine put through its paces. Our upgraded test infrastructure is now operational, giving us a stronger platform for repeatable testing, validation, and continued engine development. Built to test. Built to improve. Built for what comes next. #DGPropulsion #Turbojet #AerospaceEngineering #Propulsion

We did a successful flight test — another validation of the resilience and reliability of DG Propulsion engines. An indigenous jet engine powering an indigenous loitering munition. Jets belong in the air. Enable your wings with DG Propulsion’s Engines. @hoveritofficial @KAWAUAVPVTLTD

Sometimes I realise we’re not just building jet engines. We’re also creating one of India’s first teams of privately trained turbo-machinery engineers. A lot of legacy to be made and a lot of engineering knowledge to be compounded. It is probably one of the most interesting engineering jobs you’ll ever have. Where there’s No fear of failure. Just jet noise everyday (Ear protection mandatory.)

Work is progressing on our next test cell. Bigger. Better. More capable. Funny how priorities change. Concrete structures. Bigger exhaust ducts. Heavier test stands. New production equipment. That’s the kind of progress that makes me smile.

Jet engine development is capital intensive. Single crystal blades don’t come easy. Advanced alloys don’t come easy. A century of accumulated know-how doesn’t come easy. Other countries and companies have spent decades and billions building this capability. As a country, we need to recognize that there are no shortcuts here.

Faster spool ups are crucial for certain missions where the engine must transition from a dead start to producing thrust within seconds. In this video from confirmed ignition to idle time in under 15 seconds. It’s important to note that this is a larger engine with a heavier rotor and significantly more inertia. And despite these challenges, we repeat this repeatedly.

BIGGER. BETTER. ENGINES. That’s the entire strategy. Build. Test. Break. Fix. Repeat. Work is underway on a new modular test stand capable of supporting engines up to the 10 kN class. Everything else is noise. At DG Propulsion, the jet engines do the talking.

We are building jet engines. They don’t dance on stage. They don’t give interviews. They don’t chase headlines. They are expected to work. On land. In the air. And maybe someday at sea as well. #DGPropulsion

Just got out after visiting a customer/partner’s facility. It is one thing to hear and read about drone warfare and quite another to witness it firsthand. The future is both extraordinary and concerning.

Testing a jet engine in the middle of an Indian summer is an experience of its own. A jet engine of our size can complete one air change of the entire test cell in less than 40 seconds. Add 48°C ambient temperatures and the immense heat coming off the engine, and the local environment gets uncomfortable very quickly. Then do it again. And again. Multiple runs a day. Multiple days a week. We don’t have the facilities of Rolls-Royce or GE. We are building capability one test at a time, with the infrastructure we have. Not everyone can sit in air conditioning. Some people have to be out there with the hardware. I am out there because I want to see those test runs myself. Nobody teaches you this part.

The trees I like. Hardware founder’s desk. DG all the way>

At DG Propulsion, engines undergo relentless testing so the final application succeeds when it matters. Not every day ends in success. But every test moves the hardware forward. We are relentless.

500 horses. Compact engine. kN-class thrust. Still gives me chills every single time.

Customer deliveries are underway. Years of iteration packed into one box. 🧿 There’s a potent piece of engineering inside this box.
