Job Description
Job Description At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world's most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world. Collins Aerospace is seeking an experienced Principal Dynamics Engineer who will provide support for the Aircraft Wheels & Brakes product line as it relates to managing the dynamic response to braking (friction induced vibration) and other sources of excitation due to product operation. You will support commercial and military product lines, with focus on leading root cause investigations into vibration issues and leading the resultant design mitigation efforts. As part of this, you will interact with internal and external customers and collaborate with various global cross functional teams/groups. This role will be onsite at our Troy, OH facility.
What You Will Do:
Lead structural dynamics projects of aircraft wheels & brake to ensure that analytical assessment, dynamic test, system dynamic response, final report and documentation are prepared for internal and external customers. Create and validate structural dynamics models (modal analysis, stability assessment, transient analysis, etc.), using ANSYS Mechanical, LS-Dyna and other CAE tools. Determine the parameters of dynamics related dynamometer test programs for development and qualification based on Aircraft/program needs. Provide testing oversite for instrumentation, data acquisition, and data analysis. Update and validate finite element models by test data correlation. Provide design recommendations based on modeling and test results to understand and improve dynamic response as required. Resolve field/operational issues related to excessive vibrations using Root Cause and Corrective actions (RCCA). Lead technology development and analytical methods improvement by using latest CAE tools and experimental validation. Collaborate with multidisciplinary teams during product development, validation, and qualification processes while effectively prioritizing tasks, meeting deadlines, and ensuring clear communication in a fast-paced environment. Mentor junior and new engineers in learning and developing dynamics engineering skills. Review junior engineer's work package to ensure it meets technical quality and accuracy. Travel 10% domestically and internationally when circumstances permit. Perform other duties as required. Qualifications You Must Have:
Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience. 5+ years of experience with Structural Dynamics, Noise Vibration Harshness (NVH) and/or Friction Induced Vibration product development. Experience with dynamics modeling & simulations using tools such as LS-DYNA, Abaqus Explicit, or similar. Experience in test instrumentation, data acquisition, signal processing, and model validation associated with dynamics testing. Qualifications We Prefer:
Experience in Aero Structures/aircraft wheels and brakes. Experience in developing highly non-linear dynamic models for explicit solvers. Experience in programming/scripting using MATLAB and Python. Hands on experience in vibration testing and discrete data post processing techniques such as FFT, ODS, and other analysis methods. Knowledge and experience in complying with MIL-STD-810, DO
160 and/or other relevant standards applicable for Aerospace industry. What We Offer:
Some of our competitive benefits package includes: Medical, dental, and vision insurance. Three weeks of vacation for newly hired employees. Generous 401(k) plan that includes employer matching funds and separate employer retirement contribution, including a Lifetime Income Strategy option. Tuition reimbursement program. Student Loan Repayment Program. Life insurance and disability coverage. Optional coverages you can buy pet insurance, home and auto insurance, additional life and accident insurance, critical illness insurance, group legal, ID theft protection. Birth, adoption, parental leave benefits. Ovia Health, fertility, and family planning. Adoption Assistance. Autism Benefit. Employee Assistance Plan, including up to 10 free counseling sessions. Healthy You Incentives, wellness rewards program. Doctor on Demand, virtual doctor visits. Bright Horizons, child and elder care services. Teladoc Medical Experts, second opinion program. And more!
