Risk Mitigation During Structural Qualification of Flight Hardware

Structural qualification of flight hardware has inherent risks, including damage caused by over-test or transients caused by the abrupt shutdown of the shaker. The probability of such a catastrophe can be minimized by ensuring every part of the vibration qualification stand has been designed to protect the unit under test. The shaker, amplifier, slip table and hydraulic guidance, controller, and analyzer system all play their own critical role in protection against over-test and unwanted transients. This paper will examine the current state of technology for each of these subcomponents and will suggest best practices that mitigate the risk of damaging flight hardware during dynamic qualification.

About the event:

The 33rd Aerospace Testing Seminar

The aerospace industry is experiencing a revolution. Expanded access to space and new innovations have enabled many missions and payloads that were not possible in years past. Test efficiency must continue to be maximized while test cost and schedule are minimized for a wide spectrum of customers/programs that have very different risk postures. Additionally, testing must utilize and be integrated into the digital engineering environment.

For fifty years, the Aerospace Testing Seminar (ATS) has been inspiring engineers, managers, and leaders to share their experiences, discover new methods and procedures, and learn how others are coping with designing and implementing cost-effective and affordable test programs. ATS has been providing an invaluable forum for learning and sharing groundbreaking innovations, identifying best practices, and promoting solutions for the aerospace test industry. ATS is here to help participants tackle today’s test challenges head-on.

Topics addressed in the seminar include:

  • Strategies and Methodologies
  • Test Effectiveness and Standards
  • Modeling, Analysis and Simulation
  • Testing Challenges for Human Space Exploration
  • Digital Engineering
  • Innovations in Test Facilities and Equipment
  • Instrumentation, Data Acquisition and Evaluation
  • Testing and Verification of Additively Manufactured Hardware
