General

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

User interface

  • 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

What's New:

  • This release contains numerous bug fixes, updated 3D JOGL libraries, and separated simulation edit and plot dialogs.
