Ouch! Ka-Pow!

Gene used this photo to draw a preliminary conclusion that the forward closure of the Q-motor failed under intense heat and pressure. I’ll update if I learn more (below in comments)

Remember the O-rings on the Shuttle boosters… This is a related problem, one that I encountered on a smaller scale during my night flight on Saturday.

Last year, Gene launched a similar rocket that flew flawlessly and took photos from space, the final frontier

  1. I’m guessing that’s NOT supposed to happen.

    I hate hate hate it when people say this, but in this instance I think it’s appropriate: "Nice Capture!"

  2. Ooh shiny! Perfect shrapnelitude.

  3. Obviously a major malfunction…

    It looks like the crew has a fighting chance.

  4. heh… Yes, I’m sure Gene will be back for another go at it…. =)

    The forensic update from the field is that the forward and rear closures remained intact. The metal motor case ruptured open in the middle, a powerful and sudden CATO (or "Rapid Unscheduled Disassembly"). Looking at the photo, that explains the trajectory of the lower airframe. A forward closure failure looks more like an internal flame thrower:

  5. Spectacular – how did you capture this?!

  6. The closures and casing were fine. We looked at some of the grain porosity, and it appeared that some of the grains were not completely degassed. This will lead to significant pocketing in the propellant consistency, that will lead to pressure oscillations and an over pressure, which looks like the source of the problem.

  7. Sounds right to me!?!…;-P
    Nice frames, Steve!

  8. e-alchemist: I was shooting 400mm by hand so I could pan up as the rocket goes supersonic. Thank you Image Stabilization! For launches, I shoot 1/5000 sec timing priority. I have experimented with 1/8000 sec, but the extra tack-sharp focus afforded trades off with the aperture.

  9. Sorry I missed this launch, really feel bad for Gene!

  10. Well, worry not as WIRED issue 16.11 has a cool story and diagram of this rocket.
    .

  11. Looking through my FAVs – this picture is wonderful to explore in the original size. Shutter speed (and a bit of luck in timing does it).

  12. Yes, it is best viewed full size.

    I was also reminded today that I panned down to get Gene’s expression… photo 5 of 4 in this sequence…
