3. Launch Vehicle Loads & Design Support

• Support development of structural design load cases for different phases of flight.
• Evaluate axial/lateral acceleration, aerodynamic loads, Max‑Q, wind/gust loads, thrust loads and transient loads.
• Work with the GNC/trajectory team to obtain relevant flight conditions and load cases.
• Provide structural requirements and design inputs to the CAD/mechanical design team.
• Review structural designs and recommend modifications for strength, stiffness, weight and manufacturability.
• Participate in design reviews and technical discussions.

4. Testing & Correlation

• Support structural qualification and proof testing of launch vehicle components.
• Correlate analytical results with experimental/test data.
• Investigate structural issues identified during testing and recommend corrective actions.
