We are seeking an experienced Sr Propulsion Structures Engineer to support structural integrity and fatigue life management for gas turbine engines in development and sustainment at the Naval Air Warfare Center - Aircraft Division, Patuxent River, MD. 

US citizens only, must hold active/current DoD Secret clearance / or be able to obtain 

Must be within a commutable distance from Lexington Park, MD. This position requires ability to be on site periodically.

What you will do…

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.  

This work includes:

• Review of aircraft mission data from the U.S. Navy Fleet to develop engine usage spectra, validate propulsion system advanced lifing algorithms;
• Evaluate 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

Minimum Qualifications:

• BS 5-7 Years, MS 3-5, PhD 0-2  (MS or PhD in Aerospace or Mechanical or Materials Engineering, Physics or related engineering discipline) 
• US citizens only, must hold active/current DoD Secret clearance / or be able to obtain 
• Comfortable working in a fast-paced, startup environment.
• Prior experience working on safety-critical systems in production environments.
• High Cycle Fatigue Analysis (HCF, crack initiation predicted by a stress-life / SN approach).
• Low Cycle Fatigue Analysis (LCF, crack initiation predicted by a strain-life / e-N approach
• Experience with Finite Element Analysis (FEA / FEM) using commercial codes (e.g. ANSYS, abaqus, of NASTRAN-based solvers).
• Thermal-Structural static analysis (particularly dealing with nonlinear materials and large strains).

Desired Experiences:

Desired experience / working knowledge in propulsion system structures and fatigue life management in the following areas:

• Vibration analysis
• Turbine durability lifing methods for TMF, oxidation, erosion, and TBC coatings
• Stress analysis and fatigue of an-isotropic materials including single crystal metals and composites
• Rotor-dynamics
• Campbell diagrams including effect of, mistuning, integral and non-integral vibrations
• Airfoil creep analysis
• Probabilistic design systems
