SSI is seeking an experienced engineer to support structural integrity and fatigue life management for engines in development and sustainment at the Naval Air Warfare Center - Aircraft Division (NAWCAD), Patuxent River, MD. Be part of an exciting team making a difference for the U.S. Naval Air Forces. As a NAWCAD Propulsion Structures Engineer you will provide technical support to develop new systems and support ongoing sustainment efforts for field aircraft while mentoring journeyman engineers on component analysis and test planning efforts in the Air Systems Group, Propulsion and Power Department organization. Other job duties include:

• 
  
• Review of aircraft mission data from the U.S. Navy Fleet to develop engine usage spectra, validate propulsion system advanced lifting algorithms;
  
• Evaluation of Aircraft / Engine original equipment manufacturer (OEM) life prediction methodologies and corresponding results to support airworthiness of systems in development and sustainment of fielded assets;
  
• Establish propulsion system safety critical part life limits to prevent premature failure and develop risk mitigation strategies for field issues based on available engineering and logistical support constraints;
  
• Develop turbine engine and component test plans / procedures and execute work with limited oversight to support mitigation of service revealed deficiencies;
  
• Write and execute proposals to support workforce development, increase organic testing technologies and modeling capabilities and approaches in line with our strategic initiatives;
  
• Develop well written presentations for customers explaining the results of workforce development plans and effort;
  
• Present NAWCAD interests at symposiums and conferences
  
  •

  • MS or PhD in Aerospace or Mechanical or Materials Engineering, Physics or related engineering discipline, or Bachelor's Degree and equivalent experience in field
    
  • Coursework or transcripts showing a specialization in one or more of these related disciplines: heat transfer, structural dynamics, finite element analysis, modal test, fatigue and fracture.
    
  • 5 or more years of experience in propulsion system structures and fatigue life management including work areas such as:
    
  • Failure investigations including direction and creation of Root Cause Corrective Action (RCCA) and practical failure analysis experience
    
  • Fatigue and fracture methodologies including crack growth analysis methods and material properties behavior including damage tolerance for safety critical parts used by DoD and Commercial OEMs including ENSIP and safe-life methodologies
    
  • Turbine engine airfoil Goodman diagram limits establishment including aeromechanics data plotting, test verification standards and methods, finite element methods & strain gauge instrumentation, FOD limits, and combined stress assessments
    
  • Aeromechanics test & analysis including aero damping, turbine blade damping, and NSMS / strain gauge instrumentation
    
  • High-cycle fatigue (HCF) and low-cycle fatigue (LCF) failure modes and combinations including resonance, cycle counting / limitations and cumulative damage methods
    
  • Experience with FEA modeling of rotating turbine engine components (for a modeling SME)
    
  • Risk analyses including calculating HRI using Weibull and Monte Carlo analyses
    
  • Proficient in English and with MS Office tools to communicate ideas effectively.
    
  • Must be energetic, creative and take initiative; able to work well independently or as part of a team
    
  • Occasional travel may be required to support on-site events
    
    Preferred Skills:
    Propulsion system structures and fatigue life management experience in the following areas:
    o Vibration analysis
    o Turbine durability lifting methods for TMF, oxidation, erosion, and TBC coatings
    o Stress analysis and fatigue of an-isotropic materials including single crystal metals and composites
    o Rotor-dynamics
    o Campbell diagrams including effect of, mistuning, integral and non-integral vibrations
    o Airfoil creep analysis
    o Probabilistic design systems
