Design, Development and Mission Performance of Throttleable Engines of Chandrayaan-3 Lander

In the age of space exploration, the need of robust engines to perform a variety of operations is inexorable. Engines must cater to a variety of operations like space rendezvous, orbital manoeuvring, planetary entry and descent, and hovering and hazard avoidance during landing operations. All these operations call for a robust engine with throttling capability. This paper summarizes the development of a throttling engine of 800N thrust and its performance in Chandrayaan-3 mission.
