Project Overview

The Experimental Liquid Low Inpulse Engine (ELLIE) is the first time that STAR has attempted to create a bi-propellant rocket engine. Its purpose was to lay the groundwork for a flyable liquid in future iterations.

Since the system is our first iteration, we chose GOX (gaseous oxygen) and ETH (ethanol) as the testing propellants. We did not want to work with cryogenics such as LOX (liquid oxygen) before gaining more insight into liquid engine control.

We were able to determine the final thrust to be 32 lbf.
