This program can help students and rocketeers understand the physics of water rockets and how to optimize their water rocket launches to obtain the highest apogees. The interface is designed to be easy to use and understand. But don't be fooled by the program's simple layout, few if any of the other simulators you may find are as accurate. Under the hood this program is pretty sophisticated and thorough. The methodology includes both incompressible and compressible fluid mechanics along with a fair amount of thermodynamics and numerical methods to provide accurate water rocket apogee predictions. Check out the excellent correlation between simulation and sophisticated high speed digital camera results shown (see graphs) and at our web site. Software Includes: * Easy input of rocket launch variables * Rapid analysis of rocket launch * Generation of performance data plots * Rocket design aids & experiments * Simple launcher design blueprints * Altitude calculator

MechSpace is the AR-powered mechanism design platform for students, robotics teams, and STEM educators. Build real mechanical systems in augmented reality, simulate them with real physics, and export competition-ready code — all from your iPhone or iPad. DESIGN MECHANISMS IN AR Place gears, motors, beams, and connectors on any flat surface. Parts snap together automatically with real connection physics. Build drivetrains, lift arms, intakes, and more with parts from your favorite robotics ecosystem. REAL PHYSICS SIMULATION Run your mechanism and watch it come to life. Simple mode helps you learn the basics. Advanced mode delivers engineering-grade analysis including torque calculations, gear ratio breakdowns, friction modeling, stall diagnostics, and power consumption tracking. SCAN YOUR REAL PARTS Point your camera at VEX parts and MechSpace automatically recognizes them using on-device machine learning. Detected parts are added to your digital inventory so you always know what you have available to build with. EXPORT ROBOT CODE Turn your AR builds into real robot programs. Export C++ or Python code for VEX V5 and VEX IQ. Generated code includes motor configurations, autonomous routines, and gear ratio calculations — ready to run in VEXcode. BUILT FOR LEARNING Track your progress with build streaks, unlock achievements like Gear Master and Code Wizard, and take on timed design challenges. MechSpace makes learning mechanical engineering fun and rewarding. SUPPORTED ECOSYSTEMS - VEX V5 - VEX IQ MechSpace is completely free — all features included, no subscriptions or in-app purchases.
