N2 - Large deployable reflectors (LDRs) of typically 4 to 25 m in diameter are highly challenging key elements for space missions like earth observation (e.g. bio-mass exploration), science and communication. Such deployable apertures are large deployable parabolic reflectors and optical mirrors, as well as large planar apertures. Apart from criteria related to specific mission needs, further general criteria are also proper scalability (mechanically and RF-wise), modularity and growth potential also allowing the integration of future technologies. Several different directions of mechanical implementations of precision large apertures are addressed in the paper. These cover planar direct radiating arrays and mainly focus on large deployable reflector concepts. The discussed design concepts are substantiated by different mechanical and thermo-elastic simulation models and results, as well as results obtained from different types of tests on components and scaled laboratory models.
