Role of Structural Models in the Solar Sail Flight Validation Process

摘要

NASA is currently soliciting proposals via the New Millennium Program ST-9 opportunity for a potential Solar Sail Flight Validation (SSFV) experiment to develop and operate in space a deployable solar sail that can be steered and provides measurable acceleration. The approach planned for this experiment is to test and validate models and processes for solar sail design, fabrication, deployment, and flight. These models and processes would then be used to design, fabricate, and operate scaleable solar sails for future space science missions. There are six validation objectives planned for the ST9 SSFV experiment: (1) Validate solar sail design tools and fabrication methods; (2) Validate controlled deployment; (3) Validate in space structural characteristics (focus of poster); (4) Validate solar sail attitude control; (5) Validate solar sail thrust performance; (6) Characterize the sail's electromagnetic interaction with the space environment. This poster presents a top-level assessment of the role of structural models in the validation process for in-space structural characteristics.
