Agnibaan SOrTeD: Advancing Indigenization in India’s Private Space Sector

The Chennai-based space startup Agnikul Cosmos recently deferred the maiden sub-orbital flight of its Agnibaan SOrTeD (Sub-Orbital Technological Demonstrator) for the fourth time. While the postponement was necessitated by technical glitches identified during pre-launch checks, the mission remains a focal point for India’s burgeoning private space sector. The mission's primary objective is to flight-test the 'Agnilet' engine, which holds the distinction of being the world’s first single-piece 3D-printed semi-cryogenic engine. The Agnilet engine is a marvel of modern engineering, utilizing a semi-cryogenic propulsion system that combines liquid oxygen and kerosene. Unlike traditional engines that require the assembly of hundreds of individual parts, Agnikul’s 3D-printing process allows the entire engine to be manufactured as a single component. This innovation significantly reduces lead times, minimizes potential points of failure, and lowers manufacturing costs, making space access more commercially viable.
