The paper presents the detailed design of a conical ring constructed with V-fold bars. The discussed designs follow recent ESA patents and have been implemented in a demonstrator model, successfully manufactured and tested. The main options investigated include spring and electric motor actuation. Installation of springs in V-fold joints as well as a release cable was the first option investigated...
Large deployable antenna reflectors are commonly employed for space missions. Scientific, telecommunications and earth observation applications are enabled due to the antenna gain provided by the large apertures (8–25 m). The most relevant requirements that drive the design are the size of the stowed package diameter (0.4–1.50 m), the mass (18–160 kg), the control of the deployment process, the accuracy...
