Judging from the video, the rocket body and launcher came from TinkerCAD. From the video, it looks like these little rockets fly pretty high. The actual tube is a long piece of PVC pipe. You lock the spring and when released it punches a clean hole in the propellant casing. A 3D printed part holds a sharp point and a spring. In addition, the launch tube is pretty interesting.
JEAN PATRICE KEKA HOW TO
He read up on how to make the rocket stable (by manipulating the center of gravity versus the center of pressure) and explains what he had to do to get the rockets flying like you’d expect. You might think just sticking a CO2 cylinder in a 3D printed jacket isn’t such a big deal, but really went the extra mile. You can see them in action in the video below. But is making some really cool 3D printed rockets that use common CO2 cartridges as a propellant. And around here anything that even vaguely looks like a rocket will get some imaginary flight time. We’ve probably all made matchstick rockets as kids. You can check out the latest one from a week ago below.Ĭontinue reading “Building Homebrew VTOL Rockets” → Posted in drone hacks, Misc Hacks Tagged amateur rocketry, itar, model rocketry, rocket, vtol While hasn’t quite managed to pull off a vertical takeoff and landing with black powder motors quite yet, he’s documenting and livestreaming all of his attempts. If the second motor has sufficient impulse to make velocity and altitude equal zero at the same time, the landing legs deploy and the rocket hopefully makes a soft touchdown in the grass. During descent, the onboard microcontroller calculates the speed, altitude, and determines if it’s safe to attempt a vertical landing. Each rocket he’s built has a second Estes motor used only for landing. Taking off vertically is one thing, but is also trying to land his rockets vertically. This is active stabilization of a model rocket, with the inevitable comments of ITAR violations following soon afterward. This allows the rockets to fly straight up without fins or even the launch rod used to get the rocket up to speed in the first few millseconds of flight. is using a thrust vectoring system - basically mounting the Estes motor in a gimbal attached to a pair of servos. While the rockets coming out of Barnard Propulsion Systems look like models of SpaceX’s test vehicles, there’s a lot more here than looks. This is the hard way of doing things, and is seeing some limited success with his designs. And he’s using solid motors you can buy at a hobby shop. He’s still building a rocket that can take off and land vertically, but he’s doing it the hard way. isn’t working with the same constraints SpaceX and Blue Origin have. They’re using liquid fueled engines that can be throttled. They’re building big rockets, so there’s a nice mass to thrust cube law efficiency bump. However, both SpaceX and Blue Origin have a few things going for them. Building a rocket that takes off vertically, goes into space, and lands back on the pad is an astonishing technical achievement that is literally rocket science. No one can deny what SpaceX and Blue Origin are doing is a feat of technological wizardry.
