![]() If you are going to invest in software, you want it to have features that will allow you to try bigger, bolder, and more complex rockets. And you won't be limited to simple shapes and small rockets. These are people, like you, that really want to know with certainty how their own rocket creations will fly. RockSim is for people that like to take control of the rocket design process. But again, you are limited to simple rocket shapes, and you are not able to really predict how the rocket will actually perform. You can use one of those free "stability" programs that speed up the task of chugging through the Barrowman Equations. They are fun to do once however, you don't want to do them over and over just to make simple changes like altering the number of fins on the model. But they are time consuming to use, and they limit you to simple designs with just basic fin shapes. The Barrowman stability equations, as they are called, will help you determine if your rocket is safe to fly. You could spend hours and hours working through the stability equations using a pencil and a calculator. And even if it didn't crash, did you really learn anything new about rocketry with this method? Can you honestly say you have more information about rocket science that you can teach to others? But you can just picture for yourself that rocket you created that went unstable and smashed itself into a thousand pieces. Just copy the basic arrangement of rockets made by old-timers that have been around forever. You have several options for judging stability of a design. How is RockSim compatible with maunfacturers and other software?ĭo You Really Need A Program Like RockSim?.What are the educational benefits to using RockSim?.How does RockSim differ from other programs?.What sorts of designs can I make with RockSim?.How RockSim helps you pick the best motors for your designs & kits.How RockSim speeds up the "What if" design process.What does "Design and Simulation" software like RockSim do?. ![]() RockSim is available for both Mac and Windows, ORDER ROCKSIM NOW! More modelers, teachers, and engineers use RockSim than all the other rocketry programs combined! ![]() Use it to teach yourself and others about the physics of rocket flight. Change the engines and the weather conditions to see if you have the best choice! Because nearly every rocket manufacturer uses this software, nearly all available rocket kits have a RockSim design file that you can open using the FREE 30-day trial version. You can also use it to find the best motor and delay combinations for your existing kits. ![]() Instead of wasting money on incorrect components and numerous test motors, imagine how much money you'll save by doing all your test flights on the computer! RockSim is a computer program that allows you to design any size rocket then simulate its flight to see how high and fast it will fly! Even before you start buying components and building your design, you'll find out if it will be stable and safe to launch, as well as meet any weight, speed or height criteria you might want. It uses the Fast Marching Method to determine how a propellant grain regresses, which allows the use of arbitrary core geometries.Ĭurrent Features: * Metric and imperial units * Support for common grain geometries such as BATES, Finocyl, Star and more * Loading custom grain geometry from DXF files * A propellant editor that allows the user to enter the properties of as many propellants as they wish * The grain editor displays how a grain will regress to cut down on the guesswork involved in tweaking geometry * ENG file exporting * Burnsim importing and exporting * A UI that supports saving and loading designs along with undo and redo.Save Money And Time By Testing Your Customized Rocket Designs! The software produces estimates of a rocket motor's chamber pressure and thrust based on input such as propellant properties and grain geometry. OpenMotor is an open-source internal ballistics simulator for rocket motor experimenters. ![]()
