Pump Design Engineer – Rocket Turbopumps
BengaluruFull-time2–5 yrsPosted 2 days ago
Mid-level mechanical and production role at Astrobase Space Technologies in Bengaluru. Needs 2+ years and a B.Tech, B.E. or M.Tech.
About the role
As Pump Design Engineer, you will own the pump side of our liquid rocket engine turbopumps, from inducer to volute. You will predict how the pump should perform, compare it with test data and drive the design improvements that follow.
What you'll do
- Design the inducer, impeller, diffuser and volute for head, efficiency and suction performance
- Own axial thrust balancing of the pump: predict axial loads, design the balance features (balance piston, wear rings, balance holes) and validate them in test
- Perform NPSHR and cavitation studies: predict NPSHR across the operating range, assess cavitation breakdown and instabilities
- Maintain the pump design baseline: meanline sizing models and performance maps
- Provide inputs to CFD and FEA to check flow paths, stresses and design margins. 6. Design and own the sealing requirements for pump side streams (wear-ring leakage
What you need
- ANSYS
- MATLAB
- GD&T
- Python
- Performance testing
