Understanding Zinc-Sulfur Propellants

• for Zn-S powder motors:
  • what happens in Zn-S powder motors?
• predicting the thrust curve based on the nozzle area and the total propellant mass:
  • The pressures that can be expected?
  • the best nozzle shapes for highest impulse?
  • how to ignite and the influence of the type of ignition on the thrust curve?
  • 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?
