This consists of 4 things. Propellant density, C* / ISP*, Burn Rate Exponent (n) and Burn Rate Coefficient (a). Propellant density and C* / ISP* can be determined through ProPep software. To get the burn rate exponent (n) and burn rate coefficient (a) you need test data. Specifically, several burn rate / pressure data points. IE, at what rate does the propella...")
