Tetryl burster

The steel burster tubes from projectiles are unaffected by the caustic in the COINS. To enhance reaction rates, burster tubes are sheared into three pieces by the burster size-reduction machine to provide more surface area for the reaction of tetryl with caustic. The... 

Fuze, PDM8 is an Army SQ impact fuze used with 4.2-inch chemical cartridges. The complete assembly consists of the fuze proper with an A1 body, its various components, and a seamless steel burster tube. The bursting chge consists of ca 65 g of Tetryl pellets in the burster tube ahd lead cup. The fuze is described in Ref 52k pp 5-12 to 5-15, but a Fig is not given (Also Ref 20a, pp 272-78)... 

Fuze, PDM9 is an Army SQ impact fuze which is used with 4.2-inch HE cartridge M3- It is identical with fuze M9 except that it has a booster instead of a burster tube. The function of the Tetryl booster in fuze M9 is to transmit the shock action to TNT filler in... 

Definition of term "burster" is given in Ref 44, p B364-L and in Ref 51a, p 5-13. Explosive charges used in bursters include BkPdr, BkPdr + Mg powd (coated with oil), TNT, Tetryl or Composition B. When the burster is installed in the bomb, it fits into either the burster well or the ignition cavity Following types of bomb bursters are described in Ref 51a ... 

Bomb Burster, AN-M13., designed for use (in conjunction with igniter AN-M9) in incendiary bomb AN-M47A4, consists of a plastic tube 0.45-inches in diam, 36.0-in long, provided at each end with a soft brass cup. It is filled with ca 65 g of TNT and has a Tetryl pellet at each end (Ref 51a, P 5-15)... 

Bomb Burster, C8R1, shown in Fig 5-12, consists of a tubular fiber body, 0.47-inches in diam and 3.07-in long, partly filled with 2.5 g of Tetryl and provided with a nonelectric blasting cap at the open end of the tube. The end of the tube contg Tetryl is closed by a fiber plug. This burster is a component of igniters M15 ... 

Bomb Burster M31 consists of a cylindrical fiber body 1.44-inches in diam 7.0-in long filled with 250 g of Tetryl. One end of the body is closed by a plastic cap, while the other end by a paper disc. This burster is an integral part of nonpersistent gas bombs M125 M125A1, and is installed in the bombs during their manuf (Ref 5 la, p 5-19)... 

WWII. Tetrytols, of which 70/30—Tetryl/TNT, castable mixture is the most important in military applications. It was standardized for use in burster type of chemical shells and in demolition blocks (Ref 64, p 7-72 and Ref 70, pp 341—49)... 

A 4.2 chemical mortar shell was also used for incendiary purposes. It contained a burster charge of Tetryl, placed in thin-walled tubing extending into a cavity in the phosphorous. The Tetryl broke the shell and simultaneously ignited and scattered the burning... 

The M-47 incendiary bomb weighed approx 70 lbs and consisted of a sheet-steel cylinder with a rounded nose and tail. It was 45" long and 8-1/8" in diameter and was filled with jellied gasoline. Originally, a Black Powder central burster was used, but it was not as satisfactory as the later model with a TNT-Tetryl burster, which was surrounded by white phosphorous used as the igniter for the gasoline gel. This bomb was initiated by a nose fuse... 

Gaine (Sbeatb), A Brit, term for a metallic cup (sheath) attached to the bottom of the fuze. When filled with a comparatively sensitive HE (such as Tetryl), then connected to a detonator and inserted into a caviry in the main expl charge of a projectile (known as burster ) ic performs uie same function as a booster, described in Vol 2 of Encycl (Ref 3, pp B243 to B246-L)... 

Note. For instantaneous fuzes, the primer and upper lower detonators were enclosed in a container forming the so-called primer-detonator EvBooster. It consisted of a large amt of Tetryl enclosed in a cylindrical contai net F Burster or Main Charge. It consisted of a fairly insensitive HE, such as TNT, Amatol, Expl D, Comp B, DBX, Torpex or Ednatol which could not be initiated positively by a detonator alone... 

SAL-X Powder Mixtures. Mixts of sulfur and aluminum. Work on these mixts was undertaken during WWII during the development of the M-69 Incendiary Bomb. One lb of a mixt contg 75% Al, compressed at lOOOOpsi with a Tetryl burster, was stated to yield an expl pressure some 30% greater than an equal wt of TNT. The concn of S02 resulting from the functioning of some SAL-X mixts resulted in marked antipersonnel effects Ref A.E, Gaul L. Finkelstein, History of R D in the CWS in WWII , Vol 18, Pt 3 (Jan 1952), 103... 

Tetryl, like RDX, is a solid at the temperatures in the hydrolysis reactor. For the neat tetryl in burster charges, the grain size depends on the extent to which the pressed explosive charges have been processed prior to being added to the hydrolysis reactor. The case of tetryl in tetrytol is quite different. TNT and tetryl are very similar chemically, so the solubility of tetryl in molten TNT is quite high (82 g/100 g TNT at 80°C [176°F] 149 g/100 g TNT at 100°C [212°F]) (Kaye and Herman, 1980). Tetryl in tetrytol is mostly dissolved in the TNT phase, so the rate of dissolution and subsequent reaction in the hydrolysis medium depends mainly on the TNT/tetryl droplet size and not on the particle size of the tetryl that was originally used to make the tetrytol. 

Finding (Pueblo) EH-3. The hydrolysis of neat tetryl from burster charges is not being tested. Tests with tetrytol, which contains TNT, will not be representative of the hydrolysis of neat tetryl. 

Figure 4-3 is a flow diagram of energetics neutralization in the Parsons/Honeywell process. The feed to the energetics hydrolysis system is a slurry of burster energetics consisting of tetryl, tetrytol, or a mixture of TNT and tetryl, depending... 

Fuzes were made from a variety of primary explosives, such as mercury fulminate. The most common explosives used in burster charges are tetryl, TNT, and Composition B (a mixture of TNT and RDX). 

February and March 1943. Testers placed a 100-pound chemical bomb containing 67 pounds of CK and a 500-pound bomb containing 280 pounds of CK in shallow craters and split them open with tetryl bursters. They estimated the strength of the gas cloud by means of vapor sampling devices and goats placed downwind from the burst. The trials showed that the 500-pound bomb released a low-hanging cloud that was lethal for a considerable distance and that the flash from a tetryl burster would not ignite the compound.
