• Designing and analyzing Terran R stage 1 aft unpressurized structure, tank primary joint interface, and TVCA clevises among others. Calculated final margins for PDR and CDR maturation of these components.
• Currently supporting Terran R production start by addressing and dispositioning non conformances of both vendor-supplied machined components, as well as in-house manufactured friction stir welded structural skin.

• Collected and audited design criteria for multitude of primary structure, avionics, and valves REs to support successful Design Criteria Reviews.
• Generated composite criteria for multidisciplinary problems from structural, fluid, and thermal inputs where needed such as stage 1 main engine feedlines.

Fort Worth, Texas, United States

• Redesigned current production parts for improved fatigue performance using historical fatigue test failure investigations and FE models.
• Developed FE models using ANSYS Workbench for dynamic and drive systems components of FAA Part 29 commercial helicopter program to support damage tolerant design requirements. Parts analyzed include main rotor & tail.
• Developed FE models using ANSYS Workbench for dynamic and drive systems components of FAA Part 29 commercial helicopter program to support damage tolerant design requirements. Parts analyzed include main rotor & tail.
• Validated FE models with strain data from static load and fatigue tests. Worked with in-house Python scripts to automate FEM results post-processing and plot generation.
• Created crack no-growth threshold curves and utilized data to determine parts on which a detailed AFGROW analysis should be conducted. Worked closely with fatigue engineers on safe-life fatigue analyses. Show less
