Rock West Composites (RWC, San Diego, Calif., U.S.) announces that it has delivered a large apeture space telescope structure to its customer, (Louisville, Colo., U.S.) for its very low Earth orbit (LEO) constellation that is currently in development.
RWC provided engineering design, analysis and fabrication services for this stable structure within a compressed 6-month schedule while meeting tight requirements. Once integrated with its optics and detectors, the telescope will provide near-real-time ultrahigh-resolution earth imaging services to EOI Space’s wide customer base.
The telescope structure features mountings for three separate mirrors, as well as stress-free support of the imaging module and a decoupled mount to the spacecraft bus structure. Constructed of high modulus unidirectional carbon fiber-reinforced cyanate ester prepreg, aluminum honeycomb core and metallic inserts, the telescope was fabricated to meet the specific needs of EOI Space’s distinctive optical payload. While using the commonality of composite components to cut down on part count for the first deliverable, future iterations will be optimized for weight and producibility.

RWC provided clean sheet engineering and design for this telescope structure including static, quasi-static, modal, acoustic, thermal and deflection analysis to ensure all requirements were met for launch, orbital and operational conditions.
According to Geoff Pinto, program manager for the space telescope project at RWC, “We leveraged our deep background in stable space structure fabrication to achieve the demanding requirements of this program, and we were able to exceed those demands for our customer.”
