Abstract

Jointed-dominated deployable masts are used in space applications, including telescopes, where there is a demand for a long, slender structure that can be packed into a conventional launch shroud. Depending on the application, there may be stringent demands on the stiness and shape accuracy of the mast. This paper presents a parametric study of the signicance of a number of mast part properties for a precision deployable mast’s performance under quasi-static shear load. The mast’s cable preload, latching system behavior, and joint friction are explored as candidates for parts requiring detailed characterization for accurate mast performance prediction.
