Booster inertness

Warhead. That portion of a rocket, guided missile or torpedo designated to contain the load which the vehicle is to deliver. The load may consist of HE s, atomic bomb, chemicals, instruments or inert materials, as well as booster, fuze(s), adaption kits, and/or burster. Excludes items which contain atomic weapon components (Ref 40a, p 143)... 

Inert fuzes are provided for training ground crews in assembling handling of bombs, and also for classroom instruction of ordnance personnel. These fuzes are standard items, except that explosive components (primers, detonators, delay relay elements and boosters) are removed (Ref 51a, p 4-107)... 

If the fuze design includes a booster, an inert booster of equivalent weight and size may be substituted at the discretion of the design engineer... 

The booster-and-attenuator system is selected to provide about the desired shock pressure in the sample wedge. In all but a few of the experiments on which data are presented here, the booster-and-attenuator systems consisted of a plane-wave lens, a booster expl, and an inert metal or plastic shock attenuator. In some instances, the attenuator is composed of several materials, The pressure and particle velocity are assumed to be the same on both sides of the attenuator-and-sample interface. However, because initiation is not a steady state, this boundary condition is not precisely correct. The free-surface velocity of the attenuator is measured, and the particle velocity is assumed to be about half that. The shock Hugoniot of the attenuator can be evaluated using the free-surface velocity measurement. Then, the pressure (P) and particle velocity (Up) in the expl sample are found by determining graphically the intersection of the attenuator rarefaction locus and the explosives-state locus given by the conservation-of-mom-entum relation for the expl, P = p0UpUs where Us = shock velocity and p0 = initial density. The attenuator rarefaction locus is approximated...

Two principles can be applied in the experimental determination of the initiating strength of boosters. One relates to the determination of the damage effect caused in the witness plate by the detonation of the booster, viiereas the other concerns the determination of the capability of a booster to detonate a test explosive charge, which in addition to the explosive, also contains an inert component. The possible variant of the latter principle implies the determination of the so-called failure of detonation distance, i.e., the distance at which the detonation process is broken down. The failure of detonation distance can be determined on the basis of the traces that are left on a copper or brass plate after the detonation took place. The setup for the determination of the failure of the detonation distance is shown in Figure 2.44. 

To avoid accumulation of inerts/poisons, a small amount of gas is normally purged from the booster compressor and can be recovered into the cracker if this is available.
