This paper outlines the control structure interaction (CSI) problem for space construction engineers. An overview of the Control Astrophysics and Structures Experiment in Space (CASES)...
The Truss-Beam and Space Technology
A method is presented herein to determine the dynamic characteristics of truss-beam systems for both planar and space structures. Results from this approach are compared with those of...
Dynamics of Composite Tubes
A displacement-based stiffness method is used to study the characteristics of dispersive wave propagation in laminated composite cylindrical tubes. It is assumed that the tube is composed...
An Introduction to Pressurized Volumes in Space
Space habitation designers come from diverse backgrounds. As it is human nature to emphasize that which is familiar, habitat design is strongly influenced by the designer's...
Effect of Gravity on Dynamic Behavior of Beams
Large space structures will be needed to provide structural framework for maintaining relative positions of individual components of systems in low earth orbit. Particularly because of...
Global Problems: Implementing Mission to Planet Earth
Serious global environmental problems are facing our generation on Earth. The decrease in ozone concentrations and the greenhouse effect have implications for all life forms on the planet....
Space-Based Control of the Climate
The expected global greenhouse warming of 2 ?C may be reversed by a space-based screen that intercepts 3% of the incident solar radiation. Space-based devices may also mitigate the ozone/UV...
