Shock Release system classification

To develop a standardised (but representative) test set-up for identification of shock signature of release systems. The test setup shall have a standardised plate with a standardised I/F, bolt, boundary conditions, sensor positions and pretension load.

Experience shows that shock specifications for release systems provided by suppliers rely on different test methods and test setups. As a consequence the specified SRS are not comparable and compliance statements given in proposal phases can still impose some risk. The selection of the release system thus strongly depends on individual experience and heritage.The objective is the definition of a standardised test setup for release systems, are the generation of a shock test database which includes most used releases systems (pyro and non-pyro). This database will be complementary to the already existing one generated by the ESA/CNES pyro laboratory.
