| Abstract: |
| The Space Exploration Technologies Corporation has completed Falcon 9 Block5 launch vehicle's maiden flight recently. The general proposal of the Falcon 9 Block5 launch vehicle is studied. The technical improvement for better recycle using is introduced, including the engine promotion, the structure optimization and so on. The ameliorations and the improvement ways of main three block-upgrades have been reviewed. The influence of this maiden flight for the whole industry is analyzed, and the advice for the future commercial space transportation system development is proposed. |
