It will also let you know if your parachute deployed before or after apogee. RockSim starts its calculations and when done, it will gives a summary view that will tell you how high your design would fly, max velocity, time to apogee, and will even suggest the best delay time for that perfect recovery system deployment. You pick the engines and delay times from the included engine database (and yes, this database is also customizable), select conditions such as temperature, wind direction and speed, launch pad angle, etc. This is where I think RockSim really rocks. Once you have your design, it is time to test it. I have not yet tested this feature, but it looks way cool and I cannot wait to try it. ![]() New with version 7.04 is the ability to add decals to your design. ![]() Other views include 2D base view (great for lining up fins and launch lugs) and a 3D view that lets you look at your design in full color and from any angle. If you are designing a multi-stage rocket, you can view just the booster, just the sustainer or the whole enchilada. This screen gives you a variety of information about your design as you build it, including length, width, mass, CP, and CG locations and will even tell you if your design is stable or unstable based on Barrowman, Rocksim, or cardboard cutout methods. As you add components, you can see your rocket take shape in the 2D side view at the bottom of the screen. You start building your rocket from the top, usually starting with the nose cone. For instance, I have most of the FlisKits components entered into my database. The database is easily updated so you can add your own custom components. The RockSim component database includes a variety of parts (nose cones, body tubes, transitions, etc.) from various manufacturers like Estes, Quest and PML. You can even add color to each component for a more realistic looking rocket! It takes me about 20-40 minutes (depending on complexity) to measure the various components of a kit and enter the data into the RockSim interface. Recently, I have been concentrating on adding rockets that have reviews in EMRR but no RockSim files. I currently have over 1500 design files in my designs database. rkt files (the standard RockSim design file format) and there are many more to be found on the internet, the best source being right here on EMRR. I initially purchased RockSim to help me design scratch builds, but I have also used it to test a variety of kits that are commercially available. The RockSim software interface is easy to use and gives you enormous power over the customization of the software and of your rocket designs. It is not currently compatible with Apple MacIntosh® computers but the Apogee website says a Mac version is in the works. ![]() I installed RockSim on a computer with Windows XP, but I understand it will work with a variety of operating systems from Windows 98 on up. There have been several updates to the software, the latest version as of this writing is 7.04. I had no problems downloading the approximately 30MB file from the web site. When you make the purchase, you will receive an authorization to download the software from Apogee using a one time only login and password. I selected the immediate download option versus waiting for a CD to be mailed to me. I purchased my copy of RockSim directly from the Apogee Rockets website over a year ago.
