Developer’s description: OpenRocket 13.11.1 – A free, fully featured model rocket designer and simulator.

OpenRocket is a free, fully featured model rocket simulator that allows you to design and simulate your rockets before actually building and flying them.OpenRocket features a full six-degree-of-freedom simulation, realistic wind modeling, a multitude of different components including free-form fins and canted fins, clustering and staging. Read more about its features and see screenshots.OpenRocket is an Open Source project licensed under the GNU GPL. This means that the software is free to use for whatever purposes, and the source code is also available for studying and extending. Features:General:Fully cross-platform, written in JavaFully documented simulation methodsOpen Source, source code available under the GNU GPLUser interface:Easy-to-use user interface for rocket designReal-time view of CG and CP positionReal-time flight altitude, velocity and acceleration information from a continuous simulation performed in the backgroundZoomable schematic view of rocket from the side or rear, with rotation around the center axisDesign:A multitude of available components to choose fromTrapezoidal, elliptical and free-form fins supportedSupport for canted fins (roll stabilization)Staging and clustering supportAutomatic calculation of component mass and CG based on shape and densityAbility to override mass and CG of components or stages separatelySimulation and analysis:Full six degree of freedom simulationRocket stability computed using extended Barrowman methodRealistic wind modelingAnalysis of the effect of separate components on the stability, drag and roll characteristics of the rocketFully configurable plotting, with various preset configurationsSimulation data can be exported to CSV files for further analysisSimulation listeners allowing custom-made code to interact with the rocket during flight simulationRequires Java Runtime Environment.
