The Space Launch System and Orion spacecraft experience unique load cases during upper stage flight since the Orion must deploy its solar arrays before the upper stage engine fires. The low frequency bending modes of the deployed arrays have the potential to interact with the slosh modes of the upper stage, and with the upper stage flight steady-state accelerations this can induce high loads in the array mechanisms. A time-domain transient response solution is used to evaluate the array mechanism loads, sensitivities are noted, and the final loads are determined to be within the capability of the mechanism. Section loads and accelerations are also recovered and assessed.
