Propulsion

Specializing in pushing the limits of propulsion technology

About Propulsion

The SEDS UCSD Propulsion Team specializes in pushing the limits of propulsion technology, both at the collegiate level and in the industry. The team has a demonstrated history of firsts such as the first additively manufactured rocket engine to be hot-fired in the public domain (Tri-D) and the first additively manufactured rocket engine to be flown (Ignus I).

The Propulsion Team is currently in the process of wrapping up the design and verification of its next-generation rocket engine, Nephas.

Nephas is a throttling, thrust-vectoring, reusable, restartable, pressure-fed LOX/LNG rocket engine additively manufactured from a copper superalloy. It is designed to be a complete standalone package requiring minimal modification for integration with vehicles. Nephas will power both our Riptide lander and Halya rocket.
