In a major step toward its upcoming orbital mission, Indian space startup Agnikul Cosmos has successfully conducted a simultaneous test firing of two electric pump-fed semi-cryogenic rocket engines, both fully 3D-printed and controlled by in-house software.<\/p>\n
The company announced the achievement through a post on X (formerly Twitter), emphasising the precision and control made possible by its unique engine architecture.<\/p>\n
Humbled to share the simultaneous firing of two of our electric pump-fed semi cryo engines, controlled by our in-house engine computer software. Since these pumps are driven by electric motors there is increased level of control available to balance the thrusts across the engines pic.twitter.com\/FhYtgf5Jqo<\/a>\u2014 AgniKul Cosmos (@AgnikulCosmos) October 23, 2025<\/a><\/p>\n According to Agnikul, the test involved firing two semi-cryogenic engines powered by electric pumps \u2014 a departure from traditional gas generator or turbopump systems. Because these pumps are driven by electric motors, the company can finely adjust the thrust balance between engines using software-based control rather than mechanical methods.<\/p>\n<\/p>\n This advancement allows engineers to achieve smoother, more predictable performance and improves reliability in multi-engine configurations.<\/p>\n The engines tested were developed using the company\u2019s proprietary Agnilet technology, known for being fully 3D-printed as a single piece, without any assembled joints.<\/p>\n This design streamlines manufacturing, reduces potential leak points, and shortens turnaround times for engine production \u2014 a key factor in enabling on-demand small satellite launches.<\/p>\n The successful test marks an important milestone as Agnikul continues preparations for the launch of Agnibaan SOrTeD (Suborbital Technological Demonstrator), which will be India\u2019s first rocket powered by a completely 3D-printed engine.<\/p>\n The company operates from India\u2019s first private launchpad and mission control center at Sriharikota.<\/p>\n With this test, Agnikul strengthens its position among global private space startups pioneering advanced propulsion systems, reaffirming India\u2019s growing presence in the small satellite launch market.<\/p>\n – Ends<\/p>\n Published On: <\/p>\n Oct 23, 2025<\/p>\n
