Requirements
  • 5+ Years of experience with structural analysis of composite structures, including durability and damage tolerance analysis
  • Experience with industry standard analysis tools (Siemens NX, FEMAP/NX Nastran, AFGROW/ NASGRO, Siemens Simcenter, MATLAB)
  • History of working with cross functional teams to solve complex engineering problems
Responsibilities
  • Own the development of a system level inspection method and criteria to assess structural integrity of damaged composite structures
  • Evaluate and optimize composite structures for resistance to fatigue and fracture
  • Define program DADT requirements and methodologies for designing and analyzing damage tolerant composites structures
  • Quantify damage limits for composite structures
  • Derive material property requirements and maximum allowable flaw size requirements for damage tolerant designs
  • Assess and address nonconformances during manufacturing, testing, and field operations that may impact system DADT
  • Build and document standardized in-house tools and processes to perform DADT analysis
  • Develop company standards for composite structural analysis
  • Evaluate and optimize system (flight and ground) for structural loads, vibration modes, and deflections
  • Perform analysis and sizing of airframe primary and secondary structure including static, dynamic, stability and damage tolerance analysis for composite structures
  • Classical stress analysis (Roark/Bruhn) to do initial sizing
  • Dynamic analysis, including structural modes, random vibration, and forced harmonic vibration
  • Drive design trades with data from lightweight FEMs (Beams/Shells) that can be rapidly updated (daily) to match evolving configurations
  • Identify and define when test correlation is required to validate simulation models including static, dynamic, and flight tests
  • Produce pre-test predictions, instrumentation locations, and post test data analysis to tune model stiffness and stress results within 5% of test
  • Rapidly resolve test issues (hours) and provide corrective action direction for issues found in qualification testing
  • Work closely with design and test engineers to determine test requirements and support vehicle level tests
Desired Qualifications
  • Passion for and demonstrated history of solving complex engineering challenges
  • Vehicle/System level architecture analysis
