You could send me 'diff' files if you want. Eventually I will give you permissions to update your changes in the CVS. Are you using the latest cvs version for the moment ??

Was a decision made to use stricltly C or is C++ acceptable? I think I could significantly improve readability if I converted some of the code to C++. Parts of the code are extremely well commented, and others are very cryptic. I have finished figuring out cpropep.c and will attack equilibrium.c next. I will reserve any comments on cpropep.c until I have had time to think them through. You did a lot of work and I don't to sugest changes that are just a mater of style. Later, Dave |

I had to make the following changes to compile Cpropep with Microsoft Visual C++: In compat.h add the following one line: ------------------------------------------------------------------- #ifdef _MSC_VER /* MSVC++ 6.0 Std */ #define STRNCASECMP _strnicmp /* add for MSVC++ 5.0 */ #define STRCASECMP _stricmp <------------<<< -------------------------------------------------------------------- Later, Dave P.S. is there a better way to submit changes? |

I would be happy to look at your comments and include it. For the moment, the developpement of cpropep is quite low but I intend to do some major change. Have you any specific changes or additions you would like to do with cpropep ?

Yes, I forget to specified that r1 = r2 in the example. By the way, I will begin to test this configuration very soon. I will first try to machine a piece with this shape and cast some KNO3/Dextrose grain. I will post results when done. bye On Sun, Nov 26, 2000 at 11:47:37PM -0200, Frederico Paro wrote: > Thanks for the information.

Thanks for the information. When possible I'll take a deeper look in the star grain analysis and if there are any doubts left, I send them to the list. I'm really interested in understand a way to obtain a neutral burning in a rocket. I was really happy to find such a well explained document like this. One question: In the analisys, it's said that the r1 is 1/16 inch. What about the r2, is it, in the example in the end of the analysis, the same as r1?

Hi Frederico, the 'a angle' should always be positive. To be negative, the value of n should be > (e+Pi/2), otherwise it is positive. For the length of the star "leg", I'm not quite sure exactly what you mean. Could you send me an image with this dimension specified? I will check if it is ok. The radius r1 and r2 could be different. Good luck.

I'm studying the star grain analysis but I couldn't solve some
difficulties:
The 'a angle' , wich is the angle of the radius r1, if calculated when
n>e by the equation a=Pi/2-n+e results in a negative value. Is it
correct?
I'm don't know how to calculate the lenght of the star "leg", is it
L-x+r2 considering wx=0? Is r2=r1?
Thanks,
Fred

Hi everyone, I had a new section to the web page in the projects section concerning solid propellant grain design. As a beginning, I did the analysis of the star configuration. The document is available as html, postscript or pdf. I will eventualy add simulation software I am currently working on. I would appreciate comments about that. http://rocketworkbench.sourceforge.net/projects.phtml -- Antoine Lefebvre ant...@po... |

Hi list, I have been very busy during the summer and had not a lot of time to spent on the Rocket Workbench project. I'm sorry about that. I will have more time during next month. First of all, I would like two know if you have try Cpropep (with 178 download somebody should have try it!) and if you have any comments or bug reports about that. We are now more than 20 persons on the list. I would be interest to know what kind of implication you want to have in the projects: coding, testing, debugging, web administration, publicity,... I also upload a new version of the web page with a better look and new informations. The address is http://rocketworkbench.sourceforge.net, if somebody found any problems, please email me. For the next month, I planned to work on a grain analysis software to be used with Cpropep in order to fully caracterize solid propellant rocket motors. If you are interest to participate in the development of this software, you could talk of your idea and submit any code on this list. Thanks for your implication and I looking forward to have your comments. -- Antoine Lefebvre ant...@po... |

Hi, the first version of cpropep have been release. A windows binary have been compile by Mark Pinese. In order to try it, you should download two files from http://download.sourceforge.net/rocketworkbench/ cpropep-data-1.0.zip contain the data file need by cpropep. cpropep-win-1.0.zip contain the windows binary and an example of an input file. You could also download the source code cpropep-src-1.0.tar.gz libnum-src-1.0.tar.gz libnum contain a general matrix solution algorythm used by cpropep. I am looking forward for your comments and any bug reports. If everything goes well, I will post this mail to the arocket mailing list. Good luck and send any question to the list. -- Antoine Lefebvre ant...@po... |

Hi, A new version of the web interface of cpropep have been upload. It let you now compute shifting equilibrium performance. It should be the time to begin the comparaison of the results with those of other program like 'propep' or the nasa CEC program if somebody have access to it. It is also possible to compile your own version if you have a c compiler. I have already compile it under Linux 2.2 and AIX 4.2. Mark compile it with MSVC++ 6.0. -- Antoine Lefebvre ant...@po... |

Thanks for the suggestions. I downloaded the G77 compiler. The DOS version is actually not for DOS but rather for Win9X/NT - that is OK for me, but as I browsed through the documentation I became aware of a tool called f2c. I quickly located a version of f2c (fortran to C translator): http://sal.rising.com.au/F/1/F2C.html and it seems to work. I have not yet made any attempts to compile the resulting C code, however the primary purpose is not to make executables but rather to (perhaps?) reuse some of it. Hans Olaf Toft |

I think gcc (gnu compiler collection) does FORTRAN, and I think it's available for DOS. It's worth a look see. Try www.sunsite.unc.edu for the gnu stuff. -Larry (Have you tried linux?) C.

Hello, cpropep is now able to compute frozen and equilibrium performance for a lot of propellant. In order to do the better software, I would like to know what are the most important feature that users would need. It could also be interesting to have a graphical user interface. I will not do that, so if something is interest, contact with me. I would also like if someone could continue the job with cgi interface. I would like to concentrate myself on the problem of condensed species that lead to a lot of equilibrium problem in cpropep. As soon as this part is working, I will begin the implementation of a complete motor caracterisation software that take care of grain shape, burning rate as fuction of pressure and equilibrium caracteristic to have the thrust in function of time of a specific motor assuming frozen or equilibrium.

Hello Ray, I think the web site should contain the following sections: Goal Projects Source Code Mailing list Contacts Here is a proposition of text for those sections Goal ---- The Rocket Workbench Project have for mission to develop high quality software tools for the design of experimental rockets. We try to use the most up to date theory about rocket in order to get the most accurate results. The objective are portability between different platform and great flexibility. Projects ------- There is a lot of different aspect of the rocket that need software in order to facilitate design and analysis. Here is a list of the projects we are working on or planned to work on. Cpropep : Computation of complexe chemical equilibria of a perfect gas and pure condensed species in order to caracterize rocket performance. This software intend to be a replacement of propep with more flexibility. The documentation of propep could be see online at http://rocketworkbench.sourceforge.net/cpropep. There is also a web version online that let you try some feature http://rocketworkbench.sourceforge.net/equil.html there is also a frontend to the thermodynamic properties database http://rocketworkbench.sourceforge.net/properties.html Future project Flight simulator Heat transfer in rocket chamber Structural stress analysis of rocket chamber Grain analysis ... Source code ---------- The source code of all the software develop on the Rocket Workbench Project is release under the GPL and is free of charge. You could download the source code by ftp at ftp://rocketworkbench.sourceforge.net/pub/rocketworkbench or view the latest source on the cvs repository. You could browse the cvs online at http://cvs.sourceforge.net/cgi-bin/cvsweb.cgi/?cvsroot=rocketworkbench If you have cvs you could use the following command line argument to download the latest version. cvs -d:pserver:ano...@cv...:/cvsroot/rocketworkbench login cvs -z3 -d:pserver:ano...@cv...:/cvsroot/rocketworkbench co modulename where modulename is the name of a project like 'cpropep'. There will be binary distributions of the software as soon as the code is ready. Mailing list ------------ The discussions about development is done by the mailing list. You could get the information at http://mail1.sourceforge.net/mailman/listinfo/rocketworkbench-devel. Contacts -------- Project administrator: ant...@po... Webmaster: Could be the adress of Ray -------------------------------------------------------------- If you have any proposition or modification to do, please reply. I will try to find someone to do a logo that will look professional. Antoine On Mon, Apr 10, 2000 at 10:03:16AM -0700, Ray Calkins wrote: > Hi Antoine: > > My sincere apologies about the web page.
