Title: Mechanical Design Engineer - Machine Design/Vibration – 2258
Position Type: Regular, Full-Time
Pay Type: Exempt
US Citizenship Required
This opportunity is being offered by National Aerospace Solutions, the team selected by the U.S. Air Force to conduct Test and Operations Sustainment at the Arnold Engineering Development Complex (AEDC), Arnold Air Force Base, Tennessee. AEDC operates more than 55 aerodynamic and propulsion wind tunnels, rocket and turbine engine test cells, space environmental chambers, arc heaters, ballistic ranges and other specialized units located in six states. Many of the complex's test units have capabilities unmatched elsewhere in the United States; some are unique in the world. AEDC is one of three installations which are part of the Air Force Test Center (AFTC), one of six subordinate commands of the Air Force Materiel Command organization and an important national resource.
AEDC’s mission is to conduct developmental test and evaluation for the Nation through modeling, simulation, ground and flight test. Execution of the mission requires a large team of highly qualified and dedicated professionals from multiple technical disciplines to effectively accomplish the objectives of our test customers.
NAS currently has an exciting opportunity available for a Mechanical Design Engineer with a Machine Design/Vibration focus, to join our team in Tullahoma, TN.
The Mechanical Design Engineer will have demonstrated competence in solid modeling, application of GD&T, and in structural induced/flow induced vibrations. This Engineer will independently perform complex design and analysis tasks, lead teams in development of designs, check design packages, lead design reviews, and mentor/oversee early career engineers.
Mechanical Design Engineers
design, evaluate, analyze, and assist in the fabrication and installation of hardware across the complex, including drive systems, mechanisms, and test hardware. Mechanical design engineers work closely with test and system engineers in development of design requirements and ensuring proposed designs meet those requirements. Close coordination with manufacturing is required to ensure economic and feasible designs.
Some specific tasks associated with this type of work include (this is not an exhaustive list
- Develop concepts for new hardware and provide thermal, structural, flow, or any other required analysis to support the proposed design.Evaluate the analysis results for suitability relative to applicable codes and standards.
- Designing one-of-a-kind of mechanisms, wind tunnel models, and test fixtures including associated stress analysis.
- Provide engineering support to the appropriate craft workforce to facilitate maintenance and repair of existing systems.Evaluate existing hardware for safety, security and potential for improvement.
- Analyze static and dynamic loads, deflections, stress, heat transfer, thermal stress, thermal growth, natural frequencies and mode shapes in support of new component develop and/or component or facility modifications.
- Work with the design team (drafters, checkers, etc.) to produce complete design packages, including detailed drawings, analysis reports, and equipment specifications, and be capable of communicating the details of these design packages to the remaining project team (system engineers, test engineers, project managers, craft supervisors, etc.)
- Coordinate with the appropriate system engineer, craft supervisor, and/or work planner to ensure that hardware is fabricated and installed in accordance with the approved design package.
- It is a condition of employment to wear company issued PPE (Personal Protective Equipment) in accordance with supervisory direction and company policy.
- Perform other related duties as required.
- B.S. degree in mechanical engineering from an accredited college or university plus 5-7 years of progressive and relevant experience in machine design, mechanism design, stress analysis, and vibration analysis.
- U.S. Citizenship is required
