Ballistic Evaluation of Inhibited Propellants

This is a functional test and it is generally carried out with a sustainer propellant having combustion duration =10-12 s. It is believed that if the inhibition system functions successfully in sustainer mode, it will function similarly in other modes as well. 

If the pressure-time profiles are smooth and flat in all cases, the inhibition system is inferred to function satisfactorily and meets the requirement. Further, the expected pressure is theoretically calculated based on Equation 4.24,and should be comparable to the pressure level determined experimentally.
