Helios Hot Fire Test

On May 16, 2024, MIT Rocket Team Liquid Propulsion successfully hot fire tested Project Helios, a bi-propellant liquid rocket engine utilizing liquid oxygen and ethanol as propellants. This was the conclusion of Project Helios and Liquid Propulsion's first hot fire test in 10 years since Project Pyralis. Helios achieved peak thrust momentarily before the nozzle ablated per its design.

Are you up for any project regarding this like making own model and simulation of it?

Hybrid?

Probably just the nozzle ablating and melting XD
