SpaceX fully reusable launcher

How about a fully reusable launcher with fully reusable side boosters? If cross-feed were used, would that result in the first-stage core booster going too high for the heat shield currently envisioned to protect it during descent? I presume you're referring to the Falcon Heavy, of course. What leads you to believe its first-stage core achieves a greater altitude than the standard Falcon 9? -- dglow I thought I read somewhere that by the time the side boosters on the Falcon Heavy drop away, the core first-stage is almost full because of the cross feed going on with the side boosters. If it's close to full when the side boosters separate, I assume it would go higher before second-stage separation than the Falcon 9 first-stage. I could most definitely be wrong though ;-) |

In this SpaceX animated video -- http://www.youtube.com/watch?v=p176UpWQOs4 -- the launcher reminds me of the Falcon 9; it looks like the first stage has nine engines. I've started a thread on sci.space.policy about this ("Falcon 9 on the way down") that doesn't require response moderation. For my opinions on this look there. Dave |
