110kg sounding rocket that runs on apcp
im trying to understand the steps to building this rocket what equations do i use to find nozzle parameters and estimated burn time etc. initial surface area for the fuel block is 5020cm^2
burn rate is .6 to 1.2mm a second fuel weight is 100kg gamma for exhaust gasses is 1.24 burn temperature is 4300 kelvin and pressure is 9 Mega pascals diameter is 16 cm length is 4 meters i know some physics but have trouble finding the right equations online
