Opis:
The sensitivities of energetic materials as well as advanced energetic solid propellants are invariably associated with the nature of the stimuli that are responsible for the initiation of their decomposition. Hence it is important to study the chemical processes involved with these decompositions. While assessing the potential application of new propellant formulations containing energetic materials, it is important to assess their sensitivity to the hazards involved during their handling, transport, storage and use. This paper reports the results of impact, friction, heat, spark and shock sensitivities of advanced high energy solid rocket propellant formulations based on nitrate ester plasticized, hydroxyl terminated prepolymer (SPB-255) as an energetic binder loaded with solid ingredients like ammonium perchlorate (AP), aluminium (Al) and cyclotetramethylenetetranitramine (HMX). The results of the small card gap test showed that they are more sensitive than a composite modified double base (CMDB) propellant, which in turn is more sensitive than double base (DB) as well as composite propellants. Deflagration to detonation transition (DDT) tests carried out for the advanced energetic propellant did not show any detonation phenomena. Trinitrotoluene (TNT) equivalence and super large scale gap (SLSG) tests have been carried out for the determination of hazard classification of the energetic solid rocket propellant. The requirements to achieve both higher performance in terms of improved energy (i.e., specific impulse, Isp) and reduced sensitivity for the same propellant composition are contradictory; one should be sacrificed for the other, within manageable limits.
