Have you ever built a heliroc? Do you know what a heliroc is? Read on....
A heliroc is a rocket that deploys several blades at apogee instead of a parachute or streamer. These blades autorotate to control the descent of the rocket.
The club challenge for 2018 is to build a heliroc and launch it at the October meeting. The one that stays aloft for the longest wins.
Just to add a bit of spice to the challenge everyone has to use an A impulse motor.
Apogee's Heliroc Kit looks interesting if you're trying helirocs for the first time. There are a series of videos showing how to assemble it: video 1, video 2, video 3, video 4, video 5, video 6, video 7 . These might give you some ideas for your own design.
There's some useful information about designing your own heliroc by George Gassaway. These are aimed at B impulse motors, but the Rotaroc design has been flown successfully on A impulse. Follow this link for more information.
