Deployable structure for a CubeSat-based Cassegrain telescope

Le résumé fourni par la source

CubeSats offer a cost-effective alternative to traditional larger satellites but suffer from reduced payload capabilities due to volume constraints. A deployable Cassegrain telescope for a 6U CubeSat utilizes a high-precision deployable structure to enhance imaging capabilities while maintaining a compact launch configuration. Optical alignment tolerances are determined using ray tracing simulations, emphasizing the critical importance of precise axial positioning of the secondary mirror. The deployment mechanism consists of titanium beams that deform into a helix during the collapsing sequence, storing elastic energy for deployment. Centrifugal brakes ensure a controlled deployment sequence. In addition, self-locking hinges significantly increase the system eigenfrequency, minimizing the impact of vibrations on optical performance. A deployable baffle system is incorporated to mitigate stray light. We provide an overview of the proposed deployable telescope project and highlight the need for several critical subsystems.
