The GLR Sledgehammer roared off the pad on an Aerotech M1315 motor, flying straight and punching a hole through the clouds.

Here is a short video from the flight line. It gives a sense of the sound, but misses the subwoofer feel…

She flew perfectly, the redundant flight computers performed according to plan, and the airframe returned in sections on two huge parachutes with nary a scratch. And that was all necessary to get my L3 Certification with Tripoli Rocketry Association. Now I can launch the really big stuff… woot!

Also, I’ll post the design schematics below. This is serial #001 of the Giant Leap Rocketry upscaled Sledgehammer, a unique and elegant Air Force-inspired design.

  1. Very cool!
    Congrats!
    Looks like some sort of vulcan ship or that russian su-47 fighter.

  2. That is DAZZLINGLY cool.

  3. *not sure he wants to see "the really big stuff"* What, like a Soyuz?

  4. Love the RocketSim post as well. Super kool!

  5. Congratulations on your L3! What a THRILL actually being there!!!

  6. Awesome! Congratulations!

  7. thanks y’all. It was a blast.

    heet_myser: Well, Wedge Oldham, of Nike Project fame

    BALLS 15 See Ya!

    has a design in the works for a 1:1 scale Mercury Redstone. You know, with a capsule you can sit in before launch….

  8. @@ 1:1 MERCURY! that is incredible. Woweee. Will he launch a dummy of 180 lbs in the capsule to show that he can land the capsule in the desert fully loaded without damage?

    That would be an incredible sight to see. That’s got to be multiple Q rockets in each stage… Please let us know when that might be going up. I’d hope that could be put on video/TV for those of us who don’t make the launch.

  9. Good lord. So, are there any restrictions (I’m thinking Homeland Security) on the size these rockets can get? I mean, anyone can get a hold of as much propellant as one needs without setting off any warning bells anywhere?

    I guess if your stream hasn’t been flagged by the Feds yet, it will be now. Sorry! 😉 I love it that you and your friends never outgrew your love of "model" rocketry. I still have fond memories of hopping on my bike after launch and pedaling madly down tractor paths between corn fields — eyes to the sky — chasing my little Estes model as it floated back to Earth. Back then, someone had come out with an SR-71 Blackbird rocket that I thought, should I come to own it someday, would be the coolest thing ever (I never got it). The picture above reminds me a bit of that model. Forget that the Blackbird was never a rocket in the first place; it was one bad ass aeronautical design.

  10. Looks like the old BOMARC AA missile, from the 50s-60s. Nice shot!!

  11. The current WIRED issue 16.11 has a cool story about this event…

    "In the bleak, seemingly lifeless terrain, the dozen or so RVs and tents look like a moon base. At the center of the camp is the Rocket Mavericks trailer. A supersize satellite dish positioned to pick up a GPS signal looms overhead. Inside the trailer are a 24-megabit satcom unit able to pump out live webcasts, a pair of Wi-Fi systems that can light 4 square miles of playa, and a Silicon Graphics workstation. Two men sweat in the cramped, un-air-conditioned space as they wrench on a black rocket 7 1/2 feet long that looks like a scaled-down cross between a ’60s-vintage X-15 rocket plane and a surface-to-air missile."

  12. Definitely a Bomarc flavor

    I remember building a model of one in the late ’50s, out of balsa, based on photos… didn’t fly well ,,, 😉
