Therefore, inflatable structures offer improvements in performance to certain types of spacecraft components. Environmental factors induce surface errors on large inflatable structures, though. This degrades performance, especially for inflatable antennas. To reduce this degradation, active and passive control systems can be used to sense errors and control the shape of the antenna. One Author: Craig M. Whittinghill. American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA In this paper we develop a mathematical model of the dynamics for an inflatable space reflector, which can be used to design a controller for the shape of the inflatable structure. Inflatable structures have very nice properties, suitable for aerospace applications. We can construct e.g. a huge light weight reflector for a satellite which. Active Control of Flexible Structures deals with vibration control for large-scale flexible structures which are, or may be, subject to a broadband primary vibration field. The authors present a complete rationale for solving problems of vibration, from experimental structural characterization to .
A modular inflatable structure consisting of thin, composite membranes is presented for use in a lunar base. Results from a linear elastic analysis of the structure indicate that it is feasible in the lunar environment. Further analysis requires solving nonlinear equations and accurately specifying the geometries of the structural members. Modeling for control of an inflatable space reflector, the linear 1-D case Voß, T., Scherpen, J. M. A. & van der Schaft, A. J., , Proceedings of the 18th International Symposium on Mathematical Theory of Networks. University of Groningen, Research Institute of Technology and Management, 12 p. Space inflatable and rigidizable structures technology is one of the emerging technologies that can potentially revolutionize the design and applications of large space structural systems. In the last two years, NASA and its industry and academia partners have made significant progress in addressing important technical challenges for the actual. A Researcher’s Guide to: Space Environmental Effects. 2. This International Space Station (ISS) Researcher’s Guide is published by Space environmental threats to spacecraft components vary greatly, based Space-exposure damage to Hubble Space Telescope multilayer insulation.

The volume is organized into five topical areas including: the effects of space operations on the Earth's environment; the effects of spacecraft charging on space systems; the effects of space radiation on spacecraft systems; the interactions between the space environment and large dimension, high-power spacecraft; and the effects of the environment on the structural integrity of space vehicles. Inflatable structures in space engineering Article in Journal of the International Association for Shell and Spatial Structures 41() December with Reads How we measure 'reads'. Structural mechanics is the study of the mechanical behavior of solids and structures. Aerospace structures differ from other structures due to their high demands for performance and lightweight. Modern aerospace structures typically require the use of composite materials, advanced multifunctional materials and thin-walled constructions. Membrane structures for space have been investigated since the ’s as an alternative to conventional structures . The ECHO balloon project by NASA in the ’s was  the first successful demonstration of inflatable membranes on a large scale. ECHO 1 and 2 were large orbiting spheres.
