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:

for Zn-S powder motors:

o  what happens in  Zn-S powder motors

• predicting the thrust curve based on the nozzle area and the total propellant      mass

o  the pressures that can be expected 

o  the best nozzle shapes for highest impulse

o  how to ignite and the influence of the type of ignition on the thrust curve

o  how to prepare Zn-S propellants

for hot cast propellants:

• what temperatures are needed for proper liquefaction
• what happens with the grain during solidification
• the problem of several cigarette grains
• the burning rate mechanism
• how to control burning rate with sulfur content
• how to get an Isp of 60s and more 

The book can be purchased in the VRO eShop
