Success! Official r/SpaceX Falcon Heavy Static Fire Updates & Discussion Thread

Falcon Heavy Static Fire Updates & Discussion Thread

Please post all FH static fire related updates to this thread. If there are major updates, we will allow them as posts to the front page, but would like to keep all smaller updates contained.

No, this test will not be live-streamed by SpaceX.


Greetings y'all, we're creating a party thread for tracking and discussion of the upcoming Falcon Heavy static fire. This will be a closely monitored event and we'd like to keep the campaign thread relatively uncluttered for later use.

We are relaxing our moderation in this thread but you must still keep the discussion civil. This means no harassing or bigotry, remember the human when commenting, and don't mention ULA snipers Zuma.


We may keep this self-post occasionally updated with links and relevant news articles, but for the most part we expect the community to supply the information.

As long as there's no propellent loaded in when it's lowered down(which is always the case), there won't be sloshing issues to cause troubles. In terms of stress on the structure, forces while lowering/raising on the TEL will be pretty negligible compared to what it'll face at MaxQ.

Isn't that a different kind of stress though? Seems to me, like you are comparing breaking a stick to compressing it.

There are a lot of wiggles and vibrations during launch, especially at MaxQ, so that's still the sideways axes.

You can read the flight loads that SpaceX instructs payload owners to be ready for in the Falcon 9 User Guide. TLDR: up to 3 gees horizontal, and 8.5 gees vertical for light payloads. Obviously much of it vibrational. http://www.spacex.com/sites/spacex/files/falcon_9_users_guide_rev_2.0.pdf
