Recent Graduate Aerospace / Mechanical CFD Engineer – NAVAIR Propulsion

Job Title: Jet Aircraft Flow Modeling Project Engineer

 

Required:

– BS in Aerospace or Mechanical Engineering, Physics or related engineering discipline

– Coursework on transcripts showing study in fluid dynamics, heat transfer, or FEA structural modeling.

– At least 2 years of experience utilizing CFD or FEA tools in a govt., industry, or academic research environment; or compelling laboratory experience such as working with wind tunnels.

 

Desired:

– MS or PhD in Aerospace or Mechanical Engineering, Physics or related engineering discipline

– Working knowledge and experience in industry and / or in graduate research project use of Large Eddy Simulation (LES) tools for the modeling of aircraft related flows and / or gas turbine engine flows.

– A working knowledge of at least one industry standard Computer Aided Design (CAD) program, such as Solidworks, Creo, Rhinoceros, or Ansys Design Modeler.

– In-depth knowledge of the detailed mathematical models used in CFD/RANS/LES tools to simulate boundary layers, predict flow separation points, model compressibility effects (shocks), and model turbulence.

– 2+ years of experience utilizing CFD / RANS / LES tools to model real-world gas turbine engine, jet or rocket flow problems.

– Proficient in the generation of high quality, high fidelity, three-dimensional mesh/grids for use in complex geometries, both using structured and unstructured mesh topology.

– Experience using high powered computers (such as the DoD HPC system) to execute programs in a remote shell, or terminal, environment. Knowledge of the Linux environment and basic commands for file transfers, logins, GUI manipulation, and networking is desired.

– knowledge or / experience using the Craft LES and / or CharLES LES tools.

 

Job Description:

The NAVAIR CFD Engineer will be expected to support and enhance current ongoing fluid dynamics analysis projects in the Propulsion and Power organization. The engineer will use in-house tools to develop 3D flow models in support of our customers. Current projects include the need to improve flow separation performance, predict flow induced forcing and heat transfer to inlets and nozzles for current and future Navy aircraft systems. Several projects involve proposing improved inlet and nozzle designs to improve the efficiency and durability of Navy and Marine Corps propulsion systems.  This exciting work includes reviewing failure information from the fleet and providing accurate and rapid results to our customers. It is expected that the engineer will be able to develop well written reports, as well as have an ability to prepare and present well developed PowerPoint presentations to non-expert (in the CFD field) customers explaining the results of research and modeling plans and efforts.  It is expected that this CFD engineer can make contributions to team projects with less supervision over time. An energetic person is sought who can learn quickly, and work well with the Technical Lead and other team members, either independently or as part of tight project teams.

Please note that U.S. citizenship is required, as is the ability to obtain and maintain a security clearance.
