Affordable, Producible, Precision RF Reflectors from Membrane Aperture Shell Technology

We propose the novel Membrane Aperture Shell Technology (MAST) approach be expanded with a specific focus on RF aperture applications. The approach is based on a proven combination of 1) continuous thin film materials with space heritage and inherent low areal density (40 to 80g/m2), 2) structural shell stiffness provided through the induction of permanent curvature, 3) more than sufficiently low surface roughness and thickness variation to satisfy all RF wavelength operations, 4) proven RF reflectivity, 5) compact roll stowage and robust passive self deployment, and when needed, 6) compatibility with active boundary control to provide initial phasing and also reject environmental disturbance effects as needed. In the Phase I, building on our base of past research, we will establish the 1) hardware feasibility studies of the basic fabrication concept (especially scalability) 2) expand preliminary heritage analysis about scalability to large sizes, and 3) address other key issues critical toward realizing “readiness for flight” and improving TRL levels. This will prepare the way for a space flight demonstration which is a key step in any realistic commercialization plan for space hardware.
