This past weekend we made our own micro-rocket kits to build & launch in the neighborhood. I’ve been working on a design framework and CAD tools to produce little rockets for which Alice can do a bunch of the construction herself. There’s only a few steps, the fins are self-aligning, etc.. Besides basics like tube and shock cord they’re made of 3D printed and CNC cut parts. Alice chose parameters for her rocket (number & shape of fins, etc.), R6<\/em>, and we worked together to tune them in a simulator to get the dynamics right. She made a schedule for the morning to get it painted in time to dry before the launch and it came out excellent.<\/p>\n

Then we put together a kit, R4<\/em>, for Brett and I literally ran it over to his house so he could furiously put it together for the planned launch two hours later (the assembled one pictured here is my copy).<\/p>\n

Brett’s rocket also came out amazing! It flew as well as it looked too, with a straight ascent, clean streamer deployment, and soft landing. Alice also had a good flight with her new rocket, and it was unfazed by colliding with a fence after drifting a bit.<\/p>\n

Model rocketry is a socially acceptable and even popular hobby.<\/p>\n

Unfortunately we lost two rockets this day. At the PARA launch we had been gifted two micro-rockets by a guy to whom I had given one of my custom launch pad adapters. One was a little glider that looped around and around beautifully in the changing winds but flew at least a quarter mile away and most likely landed on the rooftops it was last seen over. The other, just barely seen here as a small yellow line at the center of the image, was an excellent scratchbuilt micro-Skywriter, a faithful cardstock mimicry of a classic #2 pencil. It flew incredibly high for the tiny MicroMaxx motor and drifted on the descent into the rocket eating maw of a high tree. An extensive search for the glider turned up nothing, but Alice is keen to check on the pencil next time we go to the field.<\/p>\n","protected":false},"excerpt":{"rendered":"
