Agnikul Cosmos successfully fires its electric motor-driven semi-cryogenic engine

Agnikul Cosmos on Friday introduced the profitable firing of its electrical motor-driven semi-cryogenic engine, the first-of-its-kind engine in India.

In a video of the firing shared on social media by Agnikul Cosmos, the engine might be seen being throttled throughout a variety of thrusts by various the velocity of the electrical motor.

“Electrical motor-driven throttling permits for greater accuracy and speedy response — vital options for dealing with complicated trajectories. Additionally, relating to flight readiness, this check is a key milestone in direction of firing a cluster of engines collectively,” Agnikul mentioned.

The system will use the start-up’s signature single-piece engine that it has at all times used.

Together with the patented engine, many sub-systems of the pump had been additionally 3D-printed and assembled on the firm’s Rocket Manufacturing unit – 1 at IIT-Madras Analysis Park in Chennai. The motor drives and related management software program had been additionally totally designed and developed in-house.

A semi-cryogenic engine is a sort of rocket engine that makes use of a mixture of liquid oxygen, a cryogenic oxidizer, together with a non-cryogenic gas like refined kerosene. In such an engine, an electrical motor is used to energy the pumps that flow into the propellants.
