This small solid rocket motor is used to characterize new solid propellants. Using the measured pressure of multiple burns with different throat sizes, one can determine the a and n parameters and thus the regression rate.
The assembly starts by mounting the nozzle flange on the casing. Afterwards the nozzle assembly and propellant grain are inserted. Next, the pertinax bulkhead and ignitor can be placed, special attention is given to the cable as it has to be shorted at all times. Lastly the assembly is finished by screwing on the bulkhead.
This assembly, except for the fuel grain can be reused at least two times, some parts more than 10 times. This allows for quick and easy testing of multiple grains.
