Ultra-Lightweight Coilable Boom Development

The objective of this Phase I proposal is to develop a reliable, ultra-lightweight deployable boom that can be used as a critical component in future space applications that include deployable sunshades, solar sails, solar arrays, and 3-D deployable structures. Minimization of the mass associated with deployable booms combined with optimization of the stiffness properties of the booms is an important step in making the ultra-lightweight future missions achievable. For the proposed Phase I program, ABLE will implement a program approach that leverages its 25+ years deployable boom heritage to develop a coilable deployable boom system that provides low risk and mission-enabling performance. This study will be based upon incorporating high-stiffness carbon graphite or titanium rods in place of standard fiberglass rods. The approximate 3x stiffness increase and reduction in mass density will offer substantial potential overall improvements in the performance of the boom system. ABLE?s program is structured to perform system definition and evaluation of several material and structural element concepts using to be incorporated within its heritage, flight-proven coilable boom. After an initial evaluation of various options, ABLE will evaluate relative stiffness and mass versus our standard deployable boom technology. Performance improvements will be determined and documented.
