Abstract : Fluctuating pressure data obtained on the surface of a rigid 10% scale model of the MOL are analyzed. Space averaged aerodynamic design criteria in the form of octave band spectra are derived together with corresponding estimates of dynamic response. Longitudinal and lateral correlation lengths are evaluated on the meteoroid shield. An aerodynamic hypothesis explaining structural and fluctuating pressure trends is introduced. When combined with the Reynolds analogy, it furnishes a synthesis between vehicular dynamics, aerodynamics and heat transfer. Random vibration predictions reported are intended to qualitatively illustrate protuberance disturbance effects. (Author)
