Firing Agnilet - a single piece, fully 3d printed, semi cryogenic rocket engine

Agnilet is a semi cryogenic rocket engine designed for use in Agnibaan’s higher stage (Agnibaan is Agnikul’s orbital-class launch vehicle) --- This engine was fully designed and realized in India #MakeInIndia #aatmaNirbharBharat --- The version of Agnilet being tested here is the sea-level version & is regeneratively cooled as it would be in flight. --- Agnilet is literally just one piece of hardware from start to finish and has zero assembled parts. --- Usually, a rocket engine has 100s of components - namely injectors, igniter, cooling channels, manifolds for fuel and oxygen etc. All of these have been printed in one piece of hardware in a single shot here. So, what comes out of the 3d printer is directly ready to be fitted in a vehicle after standard post-processing. ---We are not aware of anyone across the world who has pushed 3d printing to this extent in making rocket engines. --- This manner of making rocket engines brings down the time taken to make a rocket engine to less than 72 hours. --- For th
