Booster charge

Gaine. An intermediate booster charge used between a detonator and an insensitive high explosive. [Pg.199]

In general, detonation test apparatus consists of a steel tube that is filled with the substance under investigation. One end of the tube is provided with a booster charge consisting of an electric detonator covered by detonative material. The other end is either closed or provided with a witness plate. One type of steel tube apparatus is provided with a velocity probe to record the shock wave velocity as shown in Figure 2.28. [Pg.79]

Tests must be performed in a bunker. The booster charge is detonated and, after the event, observations are made of the fragmentation pattern of the tube and/or the condition of the witness plate. [Pg.80]

Pentaerythritol tetranitrate (PETN) (3) is a powerful explosive which exhibits considerable brisance on detonation (VOD 8310 m/s at = 1.77 g/cm ). It is the most stable and least reactive of the common nitrate ester explosives. The relatively high sensitivity of PETN to friction and impact means that it is usually desensitized with phlegmatizers like wax and the product is used in detonation cord, boosters and as a base charge in detonators. Pentaerythritol tetranitrate can be mixed with synthetic polymers to form plastic bonded explosives (PBXs) like detasheet and Semtex-IA. A cast mixture of PETN and TNT in equal proportions is known as pentolite and has seen wide use as a military explosive and in booster charges. The physical, chemical and explosive properties of PETN commend its use as a high explosive. [Pg.88]

An explosive lens is used to generate a flat detonation wave. The explosive lens consists of two cone-shaped segments of explosives, an inner cone and an outer cone, which are fitted together as shown in Fig. 9.2. When detonation is initiated by an electric detonator, a booster charge positioned at the top-center of the inner-cone explosive detonates. Then, the inner cone detonates and the detonation wave propa-... [Pg.265]

This starts the action of other elements of explosive train which consists of a Tetryl "lead", a relay detonator, and a booster charge. The stab detonator consists of a cup, which is made of A1 or A1 base alloys if LA is one of the expl ingredients, whereas Cu or Cu base alloys are used for detonators contg MF. The cup might have any one of several designs of its sensitive end closures, such as two disk-closed ends one disk-closed end one coined end one coined end one open end and one disk-closed end one open end...

Fuze, PD M56. It is a supersensitive type used with 37-mm HE shells. The fuze consists of the following parts (See Fig 1-77), joined by threads a nose (B), a head assembly (F) snd body (L), The body holds the booster charge (M) and an interrupter (N) which contains a part of the explosive train connecting the booster with the detonator (H), which is located in its assembly (G) screwed into recess of head assembly (F).

In order to prevent any hot gas from contacting the explosive charge (in the event that any porosity exists in the shell base) a thin steel disc is welded or brazed to the shell base ( base cover ). The shell is filled with high explosive (TNT, Amatol, Pentolite etc), leaving a cylindrical cavity at the upper part for a booster charge. The neck of the shell is threaded inside... [Pg.97]

An incendiary projectile is claimed which consists of a 20mm hollow body equipped with an impact-responsive primer, a booster charge a main HE charge. The body of the projectile is of Ti or Zr which on ignition burns at temps of 2725-3325°C for up to 1 min... [Pg.347]

RDX etc. For insensitive explosives such as TNT, ANFO etc an intermediate booster charge (PETN, RDX, Tetryl, NG Dynamites etc) may be necessary between the primer charge and the main charge. For details, see Minimum Priming Charges in Vol 8 Booster in Vol 2, pp 243-246 Contact Detonation Sensitivity Test in Vol 4, pp D186-190 and the added reference of C. H. Johansson T. Sjolin, ONR SympDet (1965) p 435... [Pg.372]

In a slightly desensitized form, as for example 95/5—T4/wax or paraffin, it is used as a booster charge in ammunition (Ref 28, p 348). Belgrano (Ref 31, p 261) calls such expl T4 flemmatizzato and says that it is colored pink (rosa) in Italy. Other flemmatizzanti listed by Belgrano are NGu, DNT, mineral oil, castor oil, acetanilide, MNN... [Pg.442]

The table indicates that both.ANFO and slurries are excellent cratering explosives the effectiveness of which equals or exceeds TNT capabilities. Advantages are ease of field use, insensitivity to heat and shock — hence safe, voidless filling of holes, and low expense. Disadvantage is the need for a large booster charge for initiation... [Pg.343]

If the national origin of the expl and its functional use are considered in conjunction with the color and method of loading, it is sometimes possible to correctly identify the expl. For instance, if an American booster charge is a yellow press-loaded compound, one can be sure that it is Tetryl white booster can be either RDX or PETN. In die latter case further identification is unnecessary because both expls are practically of the same sensitivity. As PETN is slightly more sensitive, it is safer to treat the expl as though... [Pg.403]

PETN is used in detonating cords and demolition detonators. In detonating cords PETN is loaded into plastic tubes. PETN is also mixed with TNT and a small amount of wax to form Pentolite mixtures. Pentolite mixtures are used as booster charges for commercial blasting operations. [Pg.129]
