The Mighty LOX Hybrid Rocket of Bavaria

    Unlike other rockets from the continental US, international rocket groups need to contend with customs and shipping. The same process applied to the EX-3, the LOX-HTPB hybrid rocket developed by WARR, from the Technical University of Munich in Germany. EX-3 exists on the upper end of the "Q" motor impulse classification, with more than 3 times the energy of the typical bipropellant rockets that have flown until recently.
    Unlike bipropellant rockets, hybrids are loaded onto the rail with the fuel loaded, which makes it much heavier than it already is. Since the Microcosm rail is designed for even bulkier rockets that are lowered onto it by crane, breech loading the EX-3 onto the rail is a difficult and awkward task.
    Uniquely with the EX-3, the LOX fill port was accessed from a fill tube at the top of the tank. With the excessive heat of midsummer desert, filling the rocket with cryogenic propellant took quite a bit of time. The propellant fill time is impacted by the diameters of the fill and vent lines, which were smaller than usually employed, at only 6mm. Part of WARR's objectives for this test campaign was to collect data for their other cryogenic rockets in development.

    Thank you so much for the amazing cut Derek! It really captures the feeling of the two weeks very well. Keep up the great work!

    wew, that was *quite* the flame for a hybrid, very impressive.

    Thank you, Derek, for creating this awesome montage of our flight.
    What a title as well ^^

    Merica set a record of 230,000 feet with a go pro camera in outer space. You planning to do that?

    Very impressive WARR team! Derek, thank you for sharing. How high???? 🙂

      Apparently it flew to around 41600ft, which puts it just behind ERAU's bipropellant launch of the same impulse.

    Pretty rocket…

    did not look like they were satisfied with the outcome --- not sure if the goal was to reach the Kármán line

    Likely the rocket underwent roll pitch coupling as these student teams dont have enough knowledge or advanced tools for flight dynamics and keep making the fins too small ending up with rockets that have marginal stability. This has bitten most of the student large hybrid projects to date. Some great engineering in the propulsion though..

    • @DerekHonkawa
      @DerekHonkawa  9 หลายเดือนก่อน +1

      That wouldn't be my first assumption. The rocket achieved stable and steady flight throughout and into it's coasting period, and the fins appeared adequate. I've seen plenty of rockets fail under such modes, but this one is probably down to recovery electronics on the return. Knowledge and resources are in no short supply at TUM, but flight and field experience is scarce everywhere.

      As Derek said we didn't experience intertial roll coupling in flight. We were able to analyze that from our received telemetry data and the rockets impact (It came down stable in one piece under terminal velocity).

    Is there any data/ video footage from the onboard cameras?

    • @antoniosteiger9443
      @antoniosteiger9443 10 หลายเดือนก่อน +4

      Yes there is the footage we received over radio, it might be featured in our own aftermovie

      We also have a lot of data we got over telemetry

    strange they launch from the USA --- I thought it's a bureaucratic hassle for EU citizens to even go the US and even more if you want to launch a rocket ---- seems that I was wrong or there are exceptions for rocket launchers --- btw the guys chatting there have no Bavaric accent at all --- even dare to call that New Prussian ((no need to mention that most of Bavaria isn't actually Bavarian))
