Surface Optimization Techniques for Deployable Reflectors
Under this and several other programs, CTD has developed TEMBOREG deployable solid-surface reflectors (TEMBOREG Reflectors) to provide future NASA and Air Force missions and commercial communications satellites with large RF apertures that can operate at very high operational frequencies (Ka band and above). TEMBOREG Reflectors incorporate non-tensioned graphite composite membranes that are formed using conventional construction techniques and stiffened using CTD's TEMBOREG shape-memory composite panels to allow practical packaging and deployment without complex mechanisms. The simplicity of the design provides a significant cost advantage when compared to existing deployable reflector technologies, (4-fold cost reduction over mesh antenna and 2-fold reduction in manufacturing time) and the continuous graphite surface enables high frequency antenna operations at Ka band and above. CTD can stow either a Cassegrainian (center-fed) or Gregorian (offset-fed) 5m TEMBOREG Reflectors in a Falcon 1e launch vehicle. To moderate cost and fabrication time, the TEMBOREG reflector is supported by a deployable backing structure. In the proposed Phase II effort, CTD will further refine innovative backing structure developed in Phase I as well as to develop additional precision capability to enable both the high frequency (Ka band and above), large aperture (5 to 8 meters) performance required for near-term and future NASA programs.
