4.2. Payload Vibration Environment
The random vibration environment at the payload interface is encompassed by acoustics and coupled
loads analysis results. Antares does not have a specific random vibration environment for the payload.
4.2.1. Payload Acoustic Environment
The maximum expected acoustic levels within the Antares fairing are shown in Figure 4.2-1. Antares
peak acoustic environments occur at lift-off and near the point of maximum dynamic pressure. Acoustic
levels are sensitive to spacecraft geometry (fill factor), so payload specific adjustments may be neces-
sary.
