POC: Sam Yunis (


  • Create a shock prediction test bed:
    • Develop a representative testbed for use in developing shock prediction methodologies
    • Provide a mobile high-quality shock testing infrastructure (hardware, instrumentation, DAS) to advance the field in many ways
    • Conduct a series of tests on different hardware to get a broad database
    • Share test data to develop and demonstrate shock propagation methodologies
  • Part 1: ShockSat1 (2021-2022)
    • Satellite-like structure with bolted joints, bulkheads, struts, and material changes
    • Impact/Hammer, point source pyro, and line source pyro testing
  • Parts 2+ (2023+):
    • Variations on structure and mass to complicate the prediction process


  • Shock propagation prediction is lagging other analyses for the design of spacecraft
  • Semi-empirical methods of joints and distance attenuation from 1970 as still used as the baseline even though numerous studies have shown that these methods are inadequate
  • Some new analyses methods are hidden by the proprietary applications and some are massaged to match poor FEMs
  • ShockSat is designed to remedy the issues and provide data that can really be used to advance the field in the public domain


  • Sheet-metal structure
    • Simple structure with shock transmission features
    • Structure is unprotected by any proprietary or secret restrictions
  • Well correlated FEM
  • 108 channels of shock data
  • Hammer tests
  • Point source (NSD) pyro tests
  • Line source (Frangible Joints) pyro tests

Released Materials

  • CAD
  • Correlated FEM
  • 108 channels of shock data (36 accels)
  • 8 hammer tests and 4 pyro NSD tests
