Job Description:

2. Rotordynamics

You will be responsible for rotordynamic analysis and mechanical design of high-speed rotating machinery for rocket turbopump applications, including rotor dynamics, vibration, bearing and seal interactions, and stability assessment.

KEY RESPONSIBILITIES

• Owning the rotordynamics of the turbopumps, including shaft, bearing and seal characteristics, stiffness and damping.
• Analyzing critical speeds, mode shapes, Campbell diagrams and stability of the turbopumps.
• Supporting cold-flow and hot testing of turbopumps: executing tests, analyzing vibration data, mapping critical speeds and studying the stability of the system.
• Supporting modal analysis and vibration testing, and correlating analytical results with experimental data.
• Collaborating with the turbomachinery design, mechanical design and test engineering teams.
• Presenting the rotordynamic analysis, test plans and test results at the PDR, TDR and VDR,



closing out review actions and getting clearance at each stage.

REQUIRED QUALIFICATION

• Robust fundamentals in rotordynamics, mechanical vibrations and structural dynamics.
• Understanding of bearings, seals, shaft design and rotor-support systems.
• Knowledge of Campbell diagrams, critical speeds, mode shapes and stability analysis.
• Understanding of rotor balancing, unbalance response, vibration and instability mechanisms.
• Familiarity with ANSYS Rotordynamics or equivalent.
• Proficiency in Python for engineering calculations and data analysis.

PREFERRED QUALIFICATION

• Academic projects, internships or industry experience in rotordynamics, turbomachinery or high-speed rotating equipment.
• Exposure to modal testing, vibration instrumentation and experimental validation.
