Overview

Aerojet Rocketdyne is a world recognized leader in space and missile propulsion. We design, develop and manufacture solid rocket motors for tactical missions for defense applications. 

 

Aerojet Rocketdyne is seeking a Specialist Engineer, Structures & Dynamics to join our Huntsville, AL office. Under limited general direction, performs structural analysis, nonlinear material behavior and structural dynamics.

 

**This role may be filled at the currently posted level or one level higher.

Essential Job Functions (Including % of Time for Each)

Performs structural analysis to verify product designs meet 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 composite. Thermal gradients and pressure distributions as well as specified mechanical loads for these models will be provided by other analysis team members. The ability to coordinate with other team members for loads and an understanding of customer specified aerospace structural requirements is required. An ability to analyze static & dynamic loads, material nonlinearities and structural instabilities is required.
  • Using solid CAD models provided by other team members, generate FEA mesh in NX, IDEAS, 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.                                                                                                                     

Requirements

Requires a Bachelor's degree in Engineering (Mechanical, Civil, Aerospace or Engineering Mechanics) and nine (9) years of engineering experience with finite element analysis, nonlinear material behavior and structural dynamics experience, or an equivalent combination of experience and education. A Master's degree in a field of engineering that emphasizes structural analysis (majors listed above) is preferred. Demonstrated experience in performing linear, non-linear and dynamic structural analyses supporting design, development and production qualification is required. Requires proficiency using finite element analysis tools such as NX, ANSYS or ABAQUS. Knowledge and experience with aerospace product development efforts is desired. Proficiency in Microsoft Office products (Word, Excel and PowerPoint) is expected. Experience in composite structures, viscoelasticity, fracture and fatigue, solid propellant, and/or rocket motor analysis capability is a plus.

 

US Citizenship Only Required. Dual Citizenship does not meet job qualifications. Must be able to obtain and maintain a U.S. Security Clearance at the appropriate level (Requires U. S. Citizenship). Must be able to satisfy federal government requirements for access to government information.

 

 

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.
