Vibro-Acoustic Forecast for Space Shuttle Launches at Vandenberg AFB: The Payload Changeout Room and the Administration Building,

Abstract

The Payload Changeout Room and Administration Building vibro-acoustic environment is simulated for Shuttle launches at Vandenberg AFB using local responses and a source term founded on Kennedy Space Center launch pressures. Overpressure emanating from above the Launch Mount at VAFB is materially altered in form and level by site reverberations. Motion produced in simulations regularly approaches or exceeds velocity and acceleration thresholds cited for other launch support structures. Forecasts call for PCR roof displacements toward the PPR exceeding 2.0 cm for most launches. The expected maximum displacement after 5 launches is 3.5 cm. An exceedance of 5 cm can be anticipated over the facility life cycle (about 100 launches). Key words: Rocket plume acoustics; Space Transportation System Launch Environment; Vandenberg AFB; Vibro acoustics. (Author)
