DG Propulsion's J40 Jet Engine Triumphs in 1-Hour Endurance Test

Indian aerospace startup DG Propulsion Private Limited (DPPL) has marked a major success with its indigenously developed DG J40 jet engine. The engine, capable of producing 40 kgf of thrust, surpassed expectations during a rigorous one-hour endurance test, demonstrating its potential for diverse applications.

"We exceeded the highly sought-after 1-hour mark – 1 hour and 10 minutes to be precise!" stated Prateek Dhawan, director at DPPL. DPPL's team subjected the engine to challenging conditions, including fluctuating throttle settings and rapid RPM changes, to thoroughly test its limits. The J40 demonstrated exceptional stability and reliability throughout the trial.

While fuel constraints ended the test, Dhawan is confident in the engine's even greater capabilities. "Imagine what we could achieve with more resources," he noted. "This is just the beginning!"

This successful endurance test marks a turning point for India's aerospace industry. The J40's capabilities are well-suited for:

• Unmanned Aerial Vehicles (UAVs): Increased thrust and endurance directly benefit UAVs, allowing for greater range, enhanced payload capacity, and increased flexibility across military and civilian applications.
• Defense Sector: The engine's proven robustness positions it as a strong contender for defense-focused drones and various unmanned systems.

DPPL's achievement underscores the growing capabilities of Indian startups within the aerospace sector. The J40's success serves as a catalyst for further advancements in indigenous engine technology, fostering increased self-sufficiency and reducing reliance on foreign imports in critical areas.

I dont know of applications of mini jet engines. In most drones, loitering ammunitions turboprops and propellers are used. The MALE UAVs that india uses also use turboprops.
And the UAVs that use jet engines are much larger and use larger engines. I dont have much knowledge of use of these mini jet engines.

Good viewpoint but the company was encouraged to build this engine hence there must be a need.

yeah, this might find use in future, more advanced drones.

There was a similiar story yesterday of another startup making an almost identicle micro engine.

You can buy a 39.5 kgf JetPro P400 Pro turbine on e-bay for Euro's 9575.

No matter what India needs to design and develop its own indigenous engine and starting small is a starting point which can be expanded on and to build an entire eco-system in India. There is a demand for small engines but there will also be companies which can and know how to design medium sized engines but expensive to develop.

India has to develop its own jet engines which is very complicated to develop and very expensive so receiving over 80% of the technology and local production for the F414 engines is very crucial. To go beyond that it's good that we have partnered with Safran to design and develop a brand new 5th generation engine with 100% of technology ownership and made entirely in India.

This would be good for suicide drones 😹😹😹🔥🔥🔥
