  1. International Space Station:Investing in Humanity’s Future Ballute Cargo Recovery System (BCRS) for ISS Experiments David W. Smith ASTE 527 December 15, 2009 USC

  2. Space Shuttle • Unique capability - Essential to construction of ISS • Retirement will dramatically impact ISS logistics

  3. ISS Logistics in Post-Shuttle Era • Combination of multiple systems

  4. ISS Logistics in Post-Shuttle Era Up mass requirements can be met, down mass can not Source: Review of U.S. Human Spaceflight Plans Committee

  5. Limited Cargo Return Capability Soyuz – 60 kg down load Dragon – 3,000 kg down load Down-mass opportunities per year (2011-2015)

  6. Cargo Return Demand vs. Capability (NASA/JAXA/ESA/CSA) Approx. 10000 kg Dragon + Soyuz Note: Orig. Chart is pre-COTS Source: ISS Panel Report, 2005

  7. A Solution is Required Success of ISS could be impacted Solutions should Allow for increase in ISS research utilization Be made available quickly to support shuttle cargo capability gap Should contribute to future vision of ISS as means to increase world cooperation

  8. Ballute Cargo Recovery System(BCRS) Uses a ballute vice traditional TPS to decelerate return cargo for reentry Purpose - To increase utilization rate of ISS by creating greater opportunity for short turn-around experimentation

  9. Target Cargo EXPRESS Payload ISPR Volume - .06 m3 Mass - ~ 30 kg .25 m .42 m .5 m

  10. System Description Master Control Box (MCB) • Component Payload Bag (CPB) • ~ 1 m • Lower Ballute Assembly (LBA)

  11. System Description(Deployed) Component Payload Bag • Master Control Box • Ballute • Torus • Re-entry Base Plate • Compression Strut • ~ 6 m

  12. Concept of Operations Pressurize the CPB Remove EXPRESS Payload & place in CPB

  13. Concept of Operations Remove from ISS on next EVA Assemble BCRS from components stored in BCRS Locker located on truss Special Purpose Dexterous Manipulator (SPDM) maneuvers BCRS for release

  14. Concept of Operations BCRS spin up and Retrofire

  15. Concept of Operations Jettison of LBA and deployment of ballute • Re-entry

  16. Concept of Operations • Descent and Landing • Global Recovery • Water • Land

  17. Resupply CONOPS BCRS’ transported on EOTV resupply flights Dragon CPB’s LBA’s Stored in locker on Truss HTV …or internally

  18. Advantages Can increase rate of research utilization A feasible option for accommodating down-mass logistics during the post-shuttle era Can be implemented in time for need More affordable than alternatives Can de-orbit cargo in a more flexible manner Small quantities Routine, timely manner Low cost Directly to the experimenter’s location!!

  19. Limitations • Very small cargo capacity • Poor touch down accuracy

  20. The Possibilities • Realize the full potential of the ISS by maximizing its scientific benefit • Allow greater participation by non-ISS partner nations Countries with national space programs

  21. Future Work Methods for greater touchdown accuracy Methods for more accurate guidance techniques High-fidelity modeling of re-entry trajectories Sizing up ballutes for use as TPS for the ATV, HTV and Cygnus
