Posted by cortelyounext on Fri May 29 09:43:49 2026 Approaching Max Q, telemetry nominal. It might take some time but that'll buff right out.#donotfly |

It's interesting that we've been doing this for almost 70 years and it's still something that's extremely difficult to get right.*The same amount of time after the Wright Brothers' first flight was in 1972, by which point aviation was so mundane that any Joe Sweatsock could wedge himself behind a lunch tray and jet off to Raleigh-Durham. *Since New Glenn is intended to deliver a payload to orbit, I'm counting from the maiden flight of the R-7 rocket. |

Private pilots still consistently get into terrible trouble, either by flying into weather their planes aren't suited for, or by not being trained properly for the planes they are flying (e.g., JFK Jr.).As an aside, it's not rocket science that's so difficult, it's rocket engineering. The principles are very well known, but the engineering involved in precisely controlling extremely large explosions is still tricky. |

Just to oversimplify: Rocket exhaust is a controlled chemical reaction, not an explosion, just like any combustion in any other heat engine. One does not control an explosion, because by definition, allowing a reaction to explode (destroy your engine, or, hopefully not, vehicle) is to relinquish control over it. (On the same token, the phrase "controlled explosion" is a different scenario, i.e. with respect to demolition or war.) |

What about deriving the Renolds number for the combustion gas? |
