Danish Amateur Rocket Test Was a Success 39

Svippy writes "At 16:32 CEST, the amateur-built Danish rocket 'Tycho Brahe' successfully made it up and down again (Danish link)." Here's an English translation via Google Translate. The article includes a video of the launch, which is a mix of Danish media coverage and English launch chatter.

Danish Amateur Rocket Test Was a Success

    • I think the design, not the packing is to blame. Maybe someone with 'chute experience could give'em some pointers. God speed Am-Rock.

    At least link the guys [] that made it happen.

    liftoff went well, tho it was a bit wobbly there early on but at least it didn't flip over or sink back down like some of those entertaining V2 and other rocket test movies on youtube.

    The parachute failed to deploy properly, so hard to say what they will have for recovery, and hard to say if they have some flotation devices, but I assume so.

    But well done all the same. A lot better than pretty much everyone else has done on their first rocket test.

      Apparently the parachute problem happened because the launch was aborted. This made the parachute deploy at high speed, rather than at top of the trajectory where speed is low. It is ok to lose the parachute for the booster this way, but obviously they need to solve the problem for the crew module. Controlled abort is one of the great things about their current rocket, and it would be a bit counterproductive if an abort ended in impact after a few km of freefall.

      If they had used Bender instead of a dummy, they could have used his ass as a flotation device!

    • Have you been able to find what altitude they reached?

      I can't seem to find that information anywhere.

  • I don't speak Danish, but it looks to me like their parachute system did not deploy properly. Unless, that is, the rocket was SUPPOSED to plummet back to earth with a shredded ball of silk dangling above it.

      They manually aborted the burn after 21 seconds because the trajectory wasn't stable and they wouldn't risk it leaving the range. The parachutes were then deployed while the rocket was still supersonic something they were never designed for and shredded. However, the unstable trajectory was more less expected as the HEAT 1x has no active stabilization. Next years version should have active stabilization, though. Still, a quite successful launch attempt I think, especially considering the pricetag of a mere $60K!

    Video from the launch.

    (Danish commentary, but english "on air" sound).

    I love the sound of booster rockets :)

    For an amateur effort, this was great! You learn from your failures, and I'm sure they will have better success with their next launch. My best wishes to them! :-) In any case, they still made it to 10 miles altitude before it was aborted.

      Vonce rockets go up, who cares vhere zey come down?

  • That was really cool!

  • This story isn't interesting because someone launched a larger-than-usual amateur rocket that had to abort.

    The story is that this is a volunteer, part-time team working towards manned flight, and are accomplishing some impressive things along the way on a teeny budget. I'd think something about that should've been in the summary, no? Or am I the only one that didn't recognize the project offhand?
