OpenRocket 12.09.1

General

• Fully cross-platform, written in Java
  
• Fully documented simulation methods
  
• Open Source, source code available under the GNU GPL
  

• 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
  

• 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
  

• 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
