Danish Amateur Rocket Test Was a Success

Posted by Soulskill on from the congratulations-to-all dept.

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.

    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.

    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!

    I don't think you know what "exceeding the goal" means. This wasn't expected to be a perfect, smooth flight with a soft landing - it was the very first flight of an incomplete version of an all new design, and the succes criterium was simply "getting liftoff". And by that standard, it was a huge success!

    when the defined goal for the launch is something along the lines of "Get it off the ground without it exploding" then yes. "it didn't blow up" is a resounding success. the fact the abort worked, and the parachute deployed at all all can be considered resounding bonus success in this case.
