RockSim Rocketry Software

RockSim is an easy-to-use computer program that lets you design and test model rockets before you even build them! With RockSim, you can build your dream rocket right on the computer screen.
For starters you get to pick all the different parts that will make up your rocket - the nose cone, the body tube, and even the engine! RockSim has tons of rocket parts and engines already inside for you to choose from. And you can easily modify the parts to your desire. Don't like the shape of the fins, simply sketch a new shape that looks awesome for your design.
Once you've designed your rocket, the best part is you can launch it...virtually! RockSim will show an animation of your rocket blasting off and flying through the air. It calculates how high your rocket will go and how fast it will fly. It will even figure out how far it will drift when the parachute comes out. That way, you can try out different designs to see which one works best.
RockSim also has advanced features that are super impressive. You can make your rocket separate into two stages like a real spacecraft! Or you can make it do dual-deployment, which helps the rocket come down closer to the launch pad. There are all sorts of possibilities.
It's kind of like a rocket video game, except you're designing actual real-life rockets that you can then go build and launch for real once you've perfected them on the computer. RockSim is an awesome way to learn all about rocketry!
