Project Hephaestus is a liquid bipropellant throttleable engine that will be developed by two team members (Bayanni Rivera & Andrew Bromberger) over the summer for a UROP research project. The PI for the research is Prof. Jonathan How. Hephaestus will pave the way towards the integration of active controls (i.e. throttling & TVC) on team liquid engines.
