Weekend Projects – 10-Rail Model Rocket Mega-Launcher
Complete instructions for this Weekend Project can be found at http://makeprojects.com/Project/10-Rail-Model-Rocket-Mega-Launcher/243/1
Nothing is more exciting to model rocket enthusiasts than a multi-rail launcher that can blast several rockets off at the same time. For rocket clubs and events, it’s almost essential to keep things moving at an exciting pace with these types of launch systems. This 10-pad mega-launcher was developed for Cub Scout Pack 1346’s rocket derby. And now you can build it too.
This system gives kids (of all ages) the fun of pressing their own launch buttons, and for added drama, sounds a klaxon before each launch. For the finale, a “Mega Launch” switch shoots off all 10 rockets at once.
To minimize the chance of an unfired rocket left on the pad, the launcher also has always-on igniter continuity checks, using LEDs to show which igniters are ready. Blocking diodes allow dual-use of the wire harness — for continuity check and launch voltage — thus halving the number of wires to the launch bar.
To show kids and adults that the launcher isn’t actually as complicated as you might think, the workings of the system can easily be seen behind clear plastic.
For Those About To Launch, We Salute You
Our latest Weekend Project will launch not one, not two, but ten model rockets simultaneously! Built around a 555 Timer IC and a few different types of launch switches, this project is ideal for rocket clubs and launch events.
