Abstract: This paper presents a NASTRAN finite element analysis for evaluation of the effectiveness of viscoelastic damping treatments as passive controls for large flexible space manipulators. The passive ...

Abstract: Laboratory dynamic testing of large and complex space structures can be difficult and expensive, if practical at all. The use of dynamically scaled test articles is a standard approach to ...

Abstract: TWO models were tested in order to determine the adequacy of a channelization scheme for Salt River near Sky Harbor International Airport, Phoenix, Arizona. One fixed‐bed model was used to study velocity patterns, flow ...

Abstract: Prismatic elements are typical devices of natural light illumination system for redirecting and collecting daylight. Based on the principles of optics, this paper presents a simple mathematical ...
