The Analysis & Test Department of the Mechanical Subsystems Engineering Directorate (MSD) is seeking an experienced Thermal Analyst with working knowledge and documented experience in the area of Thermal Analysis and Test activities in support of all phases of programs including proposal, development and production. This includes developing and optimizing designs to work with high temperature materials, in multiple operating environments spanning the range of flight conditions.

As a core team member your tasks will include:
Analyze complex missile structures via classical and/or advanced methods of analysis
Articulate risk to various internal and external customers based on data driven solutions
Drive the final design working in a collaborative multi-disciplined environment

Analyses will cover a wide range of difficult problems, requiring solutions that are imaginative, thorough, practicable, and consistent with organization objectives. The analyses will span the spectrum from classical methods to detailed numerical solutions using computer methods and finite element analysis. Working independently or coordinating the efforts of a team, the select candidate will be expected to define the scope and level of analysis required to meet required objectives and will be held accountable for completing the work within the agreed upon cost and schedule. Serving as an organizational spokesperson the selected candidate will act as an advisor to management and customers on critical design decisions. The candidate will be expected to effectively present work products in internal and external reviews and provide expert counseling and mentoring

The selected candidate will be expected to lead diverse teams, providing technical oversight and task delegation. The customers of this position will include internal Raytheon personnel and programs as well as external Government(s) personnel and programs. The selected candidate will work with the customer and engineering leadership to define testing required to validate Thermal analyses and to verify that hardware is compliant with requirements.

  • Collaborate with the Structural analysts to analyze the Thermal integrity of thermal isolation designs including thermal protection system integration with airframe
  • Demonstrated ability to perform Thermal Finite Element Analysis using PATRAN, ANSYS or equivalent software
  • Demonstrated experience defining the thermal architecture required for both transient and steady-state thermal systems
  • Demonstrated proficiency in aerodynamic heating analysis, system thermal analysis, electronics thermal analysis for high temperature systems, thermal modeling of ablative systems, combined aero-thermal structural interactions analysis and thermal environmental test.
  • Experience developing critical thermal load cases - balancing mechanical loads and thermal loads
  • Experience estimate aerodynamic heating at a variety of fidelity levels from empirical correlations to fully-coupled CFD with chemistry
  • Thermal integrity analysis to assess Margin of Safety as well as failure. Experience with electronic reliability standards and analysis approaches.
  • Expertise performing classical methods based on fundamental equations for fluid flow, convection, radiation and conduction

Desired Education, Experience and Skills:
  • Knowledge of and demonstrated experience working with thermal protection systems and materials. Proficiency analyzing thermal protective systems and defining test methods to prove out thermal protective system designs.
  • Experience with quartz lamp, arc jet, wind tunnel and other test methods to quantify aerodynamic heating conditions and correlate aerodynamic heating models
  • Supporting development testing for material characterization as well as subcomponent and flight testing. Reduction of test results for application into vehicle analysis
  • Demonstrated experience in providing electronics cooling thermal management solutions for passively and actively cooled thermal systems
  • Familiarity with analysis approaches for heat pipes, cooling loops, thermoelectric coolers and heat exchangers.
  • Definition and execution of ground test of Thermally critical phenomena
  • Master’s in Aerospace or Mechanical Engineering
  • 25 plus years of professional experience in the Thermal analysis of complex systems that require collaboration of multiple engineering disciplines
