AI Summary

Own the functional architecture and performance of the propellant feed system for a storable bipropellant propulsion system. Define system requirements, develop fluid models, and lead verification and testing activities. Requires a Master's or PhD in Aerospace Engineering with experience in fluid simulation and propulsion design.

Key Highlights

Responsible for the full lifecycle of the propellant feed system, from architecture to verification.

Develop and maintain 0D-1D fluid system models using tools like EcosimPro.

Lead functional and performance verification including cold-flow and hot-fire tests.

Key Responsibilities

Define and maintain the functional architecture of the feed system including propellant tanks, lines, valves, filters, thrusters and instrumentation.

Perform system-level sizing, sensitivity analyses and functional simulations.

Define functional requirements for subsystems based on propellant system analyses.

Develop and maintain fluid system models (steady-state and transient) to predict pressure drop, flow rates, water hammer, thruster cross-coupling, and priming behavior.

Analyze failure modes (leakage, contamination, cavitation, fluid hammer) and define mitigation strategies and design margins.

Lead functional and performance verification: cold-flow, functional and hot-fire tests from component to assembly level.

Correlate test data against predictive models and update margins/requirements accordingly.

Support integration, qualification, and operations reviews (design reviews, FMEA, test readiness reviews).
