Wanna Buy a Reusable Rocket for 19k USD? 153

Posted by timothy from the cheap-thrill dept.
Anonymous Coward writes with story from the Mainchi Daily News: "'Earlier this month, Hokkaido University started putting its Camui rockets on the open market. Camui rockets are true rockets, being 1.6 meters long, flying at 300 meters per second and parachuting slowly to the ground after reaching heights of up to 1 kilometer.' The Camui use a mixture of fixed fuel acrylic and liquid oxygen."

    I don't want to start a holy war here, but what is the deal with you Camui rocket fanatics? I've been sitting here at my freelance gig in front of a Camui rocket (a 300m/s w/1km altitude max) for about 20 minutes now while it attempts to copy a 17 Meg file from one folder on the hard drive to another folder. 20 minutes. At home, on my Titan IV running 150m/s, which by all standards should be a lot slower than this Camui, the same operation would take about 2 minutes. If that.

    In addition, during this file transfer, the guidance system will not work. And everything else has ground to a halt. Even GPS is straining to keep up as I type this.

    I won't bore you with the laundry list of other problems that I've encountered while working on various Camuis, but suffice it to say there have been many, not the least of which is I've never seen a Camui that has run faster than its Boeing counterpart, despite the Camui's faster propellant architecture. My hobby kit model rocket with helicopter nose cose runs faster than this 300m/s rocket at times. From a productivity standpoint, I don't get how people can claim that the Camui is a superior machine.

    Camui addicts, flame me if you'd like, but I'd rather hear some intelligent reasons why anyone would choose to use a Camui over other faster, cheaper, more stable systems.

          Firework rockets usually consist of gunpowder propellant (to get them into the air), an explosive charge (i.e. more gunpowder tightly wrapped) and pellets containing various metallic compounds for the colourful 'starburst'. If you removed the pellets and packed it with your pathogen of choice it would have the desired effect.

It's made half a dozen flights on hybrid power, and a couple before that with solids. Easily clears a mile. Next to it is a LOC Magnum, a standard kit available for nearly a decade, with what has to be a good twenty flights to better than a kilometer on a "J" class hybrid.
