vrijdag, 5 oktober 2007
In 2001 VRO published a book concerning our current knowledge about zinc-sulfur propellants. This book, written by Antoon Vyverman, describes in 8 chapters and 84 pages the different aspects of the propellant. It provides information to most of the questions rocket amateurs are confronted with when using this propellant:

Relation between burning rate and pressure for Zn/S propellant

E-mail

Could you tell me the relation between burning rate and pressure for Zn/S propellant ? Is there any equation like r = bP^n that is possible to be considered for this type of fuel ? If I know burning surface and throat diameter how can I determine pressure? Can I use the same equations as I use for other solid rocket fuels ?

Zinc-Sulfur Power 3/1 Thrust & Pressure Calculator

I wrote a program to calculate to calculate the thrust and pressure of a 3/1 zinc-sulfur powder motor. The software provides the possibility to calculate the expected performance of a rocket motor filled with zinc-sulfur powder with following composition: 66,5 % zinc powder and 33.5 % sulfur. The program can be downloaded from our Library. See at the end of the article for direct links.
