Aerojet Rocketdyne is a world recognized leader in space and missile propulsion. We are currently seeking an Associate Engineer to perform structural analysis of solid rocket motor components, nonlinear material behavior and structural dynamics. This entry-level opportunity will be located at our Huntsville, Alabama facility.
Under supervision, the Associate Engineer will perform structural analysis to verify product design meets structural performance requirements.
60% - Perform structural modeling of rocket motor hardware components. Conduct closed form solutions on hardware and solid propellant grains to structurally analyze joints and preliminary size components for pressure and thermal gradient boundary conditions. Materials will be a combination of isotropic, viscoelastic and composites materials. Thermal gradients and pressure distribution, as well as specified mechanical loads for these models will be specified by other analysis team members. Coordinate with other team members for loads and an understanding of customer specified aerospace structural requirements. Analyze static and dynamic loads, material nonlinearities and structural instabilities.
Using solid CAD models provided by other team members, generate FEA mesh in NX, ABAQUS, NASTRAN and/or ANSYS. The above loads and pressures will be used in these models. Perform static structural analysis and assess operating margins. Generate and provide analysis reports and presentation materials to analysis team and customers documenting FEM and analysis results.
20% - Report status and results of analysis tasks at design and program reviews.
20% - Prepare technical reports documenting all analysis activities
Requires a Bachelor degree in Engineering (Mechanical, Civil, Aerospace or Engineering Mechanics). A Master's degree in a field of engineering that emphasizes structural analysis (majors listed above) is preferred. Knowledge of finite element analysis tools such as NASTRAN, ANSYS or ABAQUS is a plus. Proficiency in Microsoft Office products is required.
US Citizenship required. Must be able to obtain and maintain a U.S. Security Clearance at the appropriate level (U.S. Citizenship required). Must also be able to satisfy federal government requirements for access to government information, and having dual citizenship may preclude you from being able to meet this requirement.
Work Environment/Physical Requirements:
Employees in these positions must possess mobility to work in a standard office setting and to use standard office equipment, including a computer; stamina to sit and to maintain attention to detail despite interruptions; may occasionally lift/carry/push/pull up to 15 pounds; may require minimal walking, climbing, stooping, crouching, and/or bending; and vision to read printed materials and a computer screen, and hearing and speech to communicate in person and over the telephone. May require the ability to travel by air or auto. May require the use of personal protective equipment such as safety glasses, safety shoes, and shop coat. These positions may be expected to work varying shifts and hours to ensure successful operation of activities in the organization.
