Tethered Space Systems
Tethered connected systems in low Earth orbits or in deep space have been proposed for various applications. Current projects involve the study of the dynamics of multi-tether systems in LEO for atmospheric measurements and imaging, as well as multi-tether systems near the Sun-Earth or Earth-Moon libration points for astronomical observations. Feasibility of a space elevator is also being investigated. Relevant sample publications are [1-5].
Formation Flying
For some applications, using a group of small satellites working together is more efficient than putting all the instruments onto one large spacecraft. Projects on satellite flying in a formation freely or connected by tethers are in progress. The relevant sample publications are [6, 7].
Space Robotics
Dynamics and control associated with manipulator-assisted capture of satellites for servicing are under investigation. Kinematics and dynamics of multi-segmented manipulators are being studied. Pose and twist estimation of rigid bodies using a set of accelerometers are being examined. The relevant publications are [8-11].
Space Structures
Projects in this area involve dynamics and control of spacecraft with flexible appendages and the study of smart structures. Attitude control of flexible satellites using fuzzy logic is being studied. Shape and vibration control of structures using bonded piezoelectric films or crystals as actuators is under investigation. Relevant publications are [11-13].
Attitude Dynamics of Satellites Orbiting Small Bodies
The highly irregular shape of small bodies (such as asteroids), along with their rotational states, can lead to very interesting attitude dynamics. Research on attitude dynamics of satellites orbiting asteroids such Vesta, Eros and Gaspra is in progress. A sample publication is [12].
Structural Dynamics
Dynamics and stability of co-axial cylindrical shells subjected to internal and/or annular flows are being studied. Mechanics of membrane structures proposed for SAR antennas are also under investigation. Relevant sample publications are [13-14].
Fluid-Structure Interaction
Dynamics and stability of co-axial cylindrical shells subjected to internal and/or annular flows are being studied using both analytical and CFD techniques. This study has applications to the power industry. Relevant publications are [14-15].
