Project Goal

This Poppet valve is our multi role valve used for both fill and drain of both propellant volumes. This valve is designed to be a reliable normally closed valve that is pneumatically actuated by GSE.

Design Requirements

  • Cryogenic Compatible
  • Oxygen Compatible
  • = 3/8” Fill Line

  • Normally closed pressure assisted
  • Adjustable valve seat for tuning
  • Adjustable spring force
  • Minimal part count

Design Overview

Engineering Phase 1

Here is the initial assembly of the turbopump.

We observed significant cavitation at 4000 RPM.
