Dart - A Scratch Design / Build Odd-Roc
The Dart is an exercise in design: spurred on by the Estes Banshee, a
rocket with wedge shaped fins as viewed from the nose cone.
I wanted to see if this fin type could be designed using OpenRocket pods. What I found was it is possible to visually model the rocket, but it's stability as shown in Open Rocket will be off since there is no airflow over both surfaces of (6) fins. So I duplicated the design and simply used (3) fins that were twice the thickness.
OpenRocket shows its stability closer to 8%. I'll build the rocket and swing test it with the Nose Cone loose, in the event it needs more nose weight.
An Altimeter Two is concealed in one fin, the launch lug in another and a faux cannon in the third. It's a Hell-For-Stout design utilizing basswood fins and a custom redwood turned nose cone. Powered by a 24mm composite motor it's a rear eject design utilizing a spool.
