  1. Spacecraft Energy Storage and Attitude Control Alkan ALTAY Assoc. Prof. Dr. Ozan TEKİNALP TUSAŞ Aerospace Industries Inc. Middle East Technical University Aerospace Engineering Dept.

  2. Electrochemical Battery Packs Energy Storage in LEO Spacecrafts

  3. Control Moment Gyroscope ( CMG ) Attitude Control in LEO Spacecrafts

  4. IPACS - VSCMG A Variable Speed CMG ( VSCMG ) That Stores Energy IPACS Integrated Power and Attitude Control

  5. IPACS - VSCMG

  6. Conceptual Design Calculations

  7. FW - 30 FW - 60 FW - 240 CMG + Li-Ion RW + Ni-Cd RW + Li-Ion CMG +Ni-Cd Total Mass Comparison For Energy Storage and Attitude Control System Combinations Comparisons

  8. Simulation of a S/C Equipped With IPACS 60 deg of roll maneuver is expected from the spacecraft while energy is being drawn from the IPACS-VSCMGs

  9. Simulation Results • Smooth Maneuvering Capability • Both Attitude and Power Objectives Satisfied • - Uncoupled Power and Attitude Functions

  10. Simulation Results • - We are able to follow any desired spin rate profile • - Low gimbal rates due to the high angular momentum content

  11. Future Work The Solution To The Kinematic Singularity Problem : Application of “Blended Inverse” Building A Prototype ?
