IMAX Support Structure


Orbital Sciences Corp. at NASA GSFC


• Generate preliminary design of IMAX support structure
• Perform Modal Analysis, optimize to ensure maximum stiffness (to minimize
   coupling with the ORU Carrier which could result in unacceptable load
• Analyze the structure for maximum anticipated flight loads
• Perform Fracture Analysis (analysis to ensure that an undetectable flaw will
   not propagate to failure)
• Develop and support modal and static test plan, document results
