SpaceCAD rocket software lets you build your rocket from basic objects: Nose cone, tubes, transitions, launch lugs, rings, or fins. You pick these from the huge included parts database with hundreds of entries - or enter the data yourself.
SpaceCAD contains
Make sure that your rocket design makes a perfect vertical flight, even in windy conditions, by computing its stability.
SpaceCAD rocket software computes the stability for you. This is determined by the Center of Gravity (CG) and the Center of Pressure (CP). Their distance decides on the rocket's reaction to wind. If they are correctly positioned, your rocket is "stable" and will fly straight and true.
This is done while you are designing, so you can tweak your rocket until it's safe for flight!
You can build your rocket design a lot faster using SpaceCAD:
Simply print those rocket design patterns on your printer and start building your real rocket!
You do want to know the answer to the most commonly asked question: How high does this rocket go? Just use SpaceCAD rocket software!
Also, SpaceCAD helps you design a complete model rocket recovery solution. You can use multiple parachutes and even print patterns for hand-sewing them on your own - or let your grandma do it.
