COLORADO SPRINGS, Colorado USA — Apogee Components is now shipping the newest edition of its rocket design and simulation software called RockSim.
The new version 7.0 now includes advanced design features which allows for "asymmetrical" fin arrangements. This lets the rocket designer to accurately position each fin on the rocket independent of all the others. So the builder can create rockets that don't look like typical "rockets." They can now look like airplanes, or even futuristic space fighters.
This is significant, because other programs, including the older versions of RockSim, rely on the Barrowman Stability equations. The Barrowman method does not allow fins to be place on the rocket except in identical sets of 3, 4 or 6 fins. With RockSim v7, you can reposition each individual fin, (both radially and lengthwise) to any location you want.
This sounds simple, but it has drastic effects on the stability of the rocket. It is a major breakthrough that RockSim 7.0 is smart enough to know how the static stability will change when each fin is repositioned. The aim is to prevent inexperienced modelers from creating designs that will go unstable when launched.
RockSim 7.0 also includes variable wind conditions when launch simulations are run. Since wind never blows at a constant speed and direction, RockSim 7 creates a more realistic trajectory of the rocket. This gives the designer more confidence in his design, and helps aid in predicting where the rocket will land.
Finally, new in RockSim v7 is a "competition" feature that will allow modelers to test their design skills against others in virtual rocket events. The competition is set up similar to NAR style events, where one can now fly "duration" events in head-to-head competition. This is possible because RockSim 7.0 now creates random thermals (rising columns of air) that mimic real-life NAR competitions. It turns this sophisticated scientific tool into a fun and exciting game!
RockSim is the leading model rocket design and simulation software that was first introduced in 1996. It allows modelers to test their rockets — both kits and their own designs — in realistic launch conditions before they even start assembling them. This allows the modeler to make changes to the rocket to insure launch success.
A free demo version is available for modelers to check out the extensive features of the RockSim design and simulation program. For more information see the Apogee Components web site at:
