This site provides data files for use with the various flight simulators.On this page is information on the available simulator programs.See the flight simulation pagefor more information on rocket flight simulation in general.

Guys the first few were expired?!? Idk why btw guys the codes help you a lot! I mean a LOT! Guys till the peace.

There is also a simple rocket flight simulator available right on this siteas part of themotor guide.(You don't need to download any software so it works on all platforms.)

These programs are not flight simulators per-se, but are related to hobbyrocket motor analysis and simulation and you may find them useful.

If you use a program not represented here, pleaselet us knowand we'll add its info and try to help you find data for it.

AeroDRAG & Flight Simulation

AeroDRAG allows the rocketeer to quickly and easily perform rocket drag (Cd)and flight simulations up to Mach 20, including support for varying Cd with velocity.It is a for-purchase program and you can find out more at theAeroDRAG page.

AeroDRAG appears to use motor data in a proprietary format and there is no obviousway to incorporate data from this site or other sources.However, it appears to be possible to download RASP format files and manually enterthe data points and summary info.

ALT4

Rogers Aeroscience ALT4 provides advanced flight modelling,including supersonic flight.This program is not shareware, but you can purchase it fromRogers Aeroscience Software(e-mail).You can also write to them at P.O. Box 10065, Lancaster CA 93584.

ALT4 uses motor data in indivual text files with the .EDX extension.ThrustCurve.org provides data in exactly this format.You can download data files from this site,save them into your ROGERS directory,and use them without any more effort.

CompuRoc

CompuRoc is a shareware model rocketry simulator,including altitude prediction, ejection delay calculation, graphing capabilities,flight summaries, as well as a set of nice thrust curves for common real-worldmotors and complete documentation.(CompuRoc was the first simulator available for the Macintosh.)This program is shareware and you can find out morein this article.

CompuRoc uses binary motor files in a proprietary format.You can import thrust curve data from here,but you will still need to enter the motor attributes by hand once when you import.

See theRocFlight web site.

RockSim

RockSim is a full featured rocket design and simulation program from ApogeeComponents. It allows a modeler to design their rocket, and then perform adetailed and accurate simulation that predicts how well it willfly. RockSim is different from other simulators in that it calculates thechanging weight of the rocket as the motor burns off propellant. This notonly affects the altitude, but the stability and trajectory of the rocketas well. RockSim is the first and only inexpensive rocketry program thatpredicts the dynamic stability of the rocket, which is how it reacts towind disturbances. This is displayed as a movie-like animation of therocket's trajectory; so even non-scientists can easily see how the vehiclewill perform.

The software will also aid the modeler in building their rocket, as itallows printing of templates, pattern sheets, as well as 3D pictures of themodel.

RockSim accepts RASP.eng files, but for greater simulation accuracy, andease in selecting from the over 360+ certified rocket engines, users ofRockSim v8 and newer should select the 'RockSim Engine format' (.rse). Thisnewer engine format saves additional information about the rocketengine. This includes the type of motor (single-use, reloadable, hybrid),and the CG curve of the motor as it burns off propellant. This becomesimportant in hybrid motors in particular; as the CG moves rearward as theyburn, making the rocket less stable.

RockSim comes in two versions: Windows (requires Win98 or newer) andMacintosh OS X (v10.3 or newer). The design and motor data files arecross-platform compatible.You can download a trial version or purchase RockSim from ApogeeComponents:www.ApogeeRockets.com/rocksim.asp

SpaceCAD

SpaceCAD is a design and simulation environment which looks verycomplete and professional.SpaceCAD is now finished and available and you can find more at theSpaceCAD web site.

SpaceCAD uses RASP format files (.eng).Download RASP motor data files from this site and edit them into theSPACECAD.ENG file in the installation directory.However, SpaceCAD comes with an up-to-date set of motor data so this shouldn'tbe necessary initially.

See theSpaceCAD web siteor contactAndreas Firnaufor more information.

Virtual Range

Virtual Range is a rocket flight simulator for Mac OS X.With Virtual Range, you can test the stability and performance of model or high powerrocket before you launch it.The rocket's trajectory is simulated in real time and displayed on the screen,along with information such as altitude at apogee, maximum speed, and maximum acceleration.This software is offered as a free download for educational and noncommercial use.See theVirtual Range sitefor more info and to download.

Virtual Range uses RASP format files (.eng).Download RASP motor data files from this site and use them for a simulation.

WinRoc

WinRoc is a popular suite of rocketry programs,which has a very nice graphical user interface.The WinRoc programs are the easiest to use and the latest version, WinRoc 4.5,is a 32-bit program for Windows 95 and NT.You candownload WinRoc directly.

This package was written by Steve Roberson, who passed away in 2003.See the WinRoc pagefor more info.

WinRoc uses a monolothic motor database in binary format andthere is no way to add data for a specific motor without entering it in by hand.Thus, you cannot get data for WinRoc from ThrustCurve.org.See the WinRoc page above for the latest downloads.

AeroFinSim

AeroFinSim is a structural analysis program for determining the forcesacting on rocket fins and predicts the highest speed the rocket can safely attain.AeroFinSim is a Windows GUI program.

See theAeroFinSim pagefor more information and purchase details.

RockSim Engine Editor

The program 'Engine Editor' is the software that is used to create enginefiles. The process of making a motor file is straight-forward. First, theuser enters basic data about the rocket motor, such as weights, sizes, andavailable delay choices. Then the thrust curve is input into the softwareby clicking points on a grid plot. These points can be moved around tomatch the actual curve of the rocket motor. As the plot is created, thesoftware calculates the Total Impulse, average Thrust, and Specific Impulseof the engine. Finally, the file is saved to disk, in either RASP.eng orRockSim (.rse) format. While the data files are saved in metric units, theuser can enter the raw data in either English or Metric format (or acombination of both).

'Engine Editor' also has features to manage the task of organizing enginedata files. You can append two different engine files into one, or break adata file containing several individual motors into separate files.

A new feature being added to Engine Editor will allow a user to read in rawTime/Thrust data from a load cell or Excel file. This will make it easierto create the time/thrust plot for home-brew rocket motors.

The Engine Editor comes bundled with the RockSim software from ApogeeComponents. It is available for Windows (win95 or newer) or Macintosh OS X(version 10.3 or newer). You can download a trial version or purchase theRockSim/Engine Editor combo-package from ApogeeComponents:www.ApogeeRockets.com/rocksim.asp
