Description
This presentation will review the progress made by SPACEO in the field of inflatable drag devices, which are a crucial technology for the de-orbiting of satellites.
SPACEO identified and tested a range of materials tailored for the unique demands of the space environment. These materials exhibit characteristics such as extreme durability, lightness, and resistance to harsh space conditions. Validation tests performed on these materials confirmed their suitability for constructing inflatable drag devices.
Alongside materials development, SPACEO has also made strides in creating accurate and reliable sizing models for these inflatable drag devices. The models' successful validation with testing activities of inflatable beams in 3 points bending demonstrates their potential for predicting structural performance in real-world de-orbiting operations.
Significant strides have been made with the completion of Technology Readiness Level (TRL) 4, an essential step towards translating research into applicable technology. This stage involved the production and laboratory testing and model validation of a 10m2 inflatable sail and a 3m diameter torus.
These advancements by SPACEO set a precedent for future efforts in tackling the clean space problem, offering promising avenues for the efficient, safe de-orbiting of satellites. Space was recently selected by ESA BIC Portugal and will be invested by Portugal Ventures. Further research and development are underway to advance these technologies to deployment in space, paving the way for a cleaner, safer space environment.
