A Novel Axial Foldable Mechanism for a Segmented Primary Mirror of Space Telescope

Future space missions will have larger telescopes in order to look deeper into space while improvising on spatial resolution.The primary mirrors for these telescopes will be so large that using a monolithic mirror will be nearly Cloth impossible because of the difficulties associated with its fabrication, transportation, and installation on a launch vehicle.The feasibility of launching these huge mirrors is limited because of their small launch fairing diameter.The aerodynamic shape of the fairing requires a small diameter, but the height of the launch vehicle, which is available for designers to utilize, is larger than the fairing diameter.This paper presents the development of an axial deployment mechanism based on the screw jack principle.

The Aluminium Spill Tray mechanism was designed and developed, and a prototype was constructed in order to demonstrate a lab model.
