Download OpenRocket Free Rocket Simulator

OpenRocket is a free rocket simulator; it will help you design and simulate your rockets.

Features

Six-degree-of-freedom flight simulation / Automatic design optimization / Realtime simulated altitude, velocity and acceleration display / Staging and clustering support / Cross-platform (Java-based)

The main rocket design window is used to design the rocket and it also provides information about a flight simulation in real-time. You can analyze the effect of individual components on the stability, drag and roll characteristics of the rocket. The simulation results can be plotted in a multitude of ways. You can either use the predefined plot configurations or define your own. The simulations are plotted using the JFreeChart plotting library.

Easy-to-use user interface for rocket design / Real-time view of CG and CP position / Real-time flight altitude, velocity and acceleration information from a continuous simulation performed in the background / Zoomable schematic view of rocket from the side or rear, with rotation around the center axis

Design: A multitude of available components to choose from / Trapezoidal, elliptical and free-form fins supported / Support for canted fins (roll stabilization) / Staging and clustering support / Automatic calculation of component mass and CG based on shape and density / Ability to override mass and CG of components or stages separately

Simulation and analysis: Full six degree of freedom simulation / Rocket stability computed using extended Barrowman method / Automatic design optimization — you can optimize any number of rocket parameters for flight altitude, maximum velocity or a number of other values / Realistic wind modeling / Analysis of the effect of separate components on the stability, drag and roll characteristics of the rocket / Fully configurable plotting, with various preset configurations / Simulation data can be exported to CSV files for further analysis / Simulation listeners allowing custom-made code to interact with the rocket during flight simulation
