ABSTRACT

SSL has performed pyroshock qualification testing on a wide array of satellite hardware, including more than 450 tests of propulsion, mechanism, bus electronic, attitude control, RF passive, and RF active units. An analysis of shock-related hardware failures was performed to determine risk factors related to the pyroshock qualification of new units. Specific failure examples are described. The features that put units at highest risk for shock qualification failure include relays, heavy bonded or soldered elements, lightweight structural components, and brittle materials.

BIOGRAPHIES

Dr. Jennifer Dawson joined SSL in 2010 as a spacecraft systems engineer. She served as the chair of SSL's Shock Committee from 2012–2016 where she was responsible for defining company-wide shock requirements, overseeing shock anomaly resolution, and providing shock training to employees. In 2016, Jennifer was a recipient of the Society of Satellite Professionals International (SSPI) Promise Award, with her Shock Committee work highlighted by the award committee. She is now a Director of Marketing and Sales at SSL. Jennifer earned a B.S. in mechanical engineering from Bucknell University and a M.S. and Ph.D. in mechanical engineering from Stanford University, including research on two satellite programs: Gravity Probe B and Satellite Test of the Equivalence Principle.

Bobby Lyon is a student at the University of California, Santa Barbara studying toward a B.S. degree in Physics with a minor in Mathematics. In the summer of 2016, he was an intern at SSL in the Mechanical Systems department. Bobby led the pyroshock qualification data collection and analysis for this paper.

Nao Murakami joined SSL in 2016 as spacecraft systems engineer. She is currently responsible for the spacecraft-level and unit-level shock analysis code used in the Mechanical Systems department. She also implements SSL's flight shock measurement system. Nao earned a B.S. in mechanical engineering and M.Eng. in aerospace engineering from Cornell University, where she worked on two student-led satellite programs: CUSat and Violet. She is expected to receive a M.S. in aeronautics and astronautics from University of Washington in March 2017. Her thesis research was on the development of a high-power helicon “double gun” plasma thruster.
