Agnikul Cosmos presented the largest single-piece rocket engine ever built. It was made entirely of Inconel by additive manufacturing, this propellant reaches one meter in length and was produced in a single operation without welds, joints or fasteners from the fuel inlet to the nozzle outlet.
The manufacture of a rocket motor in one piece
This development also expands on the company’s previous success, which had manufactured and flight-tested a monoblock engine. The new version exceeds its predecessors in size and also integrates greater structural complexity and considerably higher weight, demonstrating the feasibility of manufacturing complete engines with a single production cycle.
Agnikul Cosmos also announced that it has obtained a patent in the United States for its design and method of manufacturing integral rocket motors. This registration consolidates an Indian design in one of the most competitive markets in the aerospace industry, recognized for developing some of the world’s most advanced propellants.
This project has been supported by organizations such as ISROIN-SPACe, TDB and DST, strengthening India’s role in the global space innovation arena. With this achievement, the company establishes itself at the forefront in the industrial application of large-scale additive manufacturing in the orbital launcher sector.
