147 Gelatins; Gelatinous <strong>Explosives</strong>; Gelignites<br />

The jet velocity is proportional to the square root of the combustion<br />

temperature and inversely proportional to the square root of the mean<br />

molecular weight of the combustion gases.<br />

Other details can be deduced from the formula.<br />

Gas Pressure<br />

Gasdruck; pression de gaz<br />

The pressure generated in the chamber of a weapon; its value depends<br />

to a large extent on the nature of the weapon and of the powder<br />

selected. Standard determinations of gas pressure are carried out with<br />

the aid of a crusher (“measuring egg”) – a copper cylinder or a copper<br />

pyramid – the compression of which is a measure of the gas pressure.<br />

A complete transient gas pressure curve can be plotted with the aid of<br />

piezo-quartz or other pressure transducer with an oscillograph (W Ballistic<br />

Bomb).<br />

GELANTINE DONARIT S<br />

Gelatine Donarit S is a blasting cap sensitive gelatinous explosive. It<br />

contains specialsensitizers and can be used under high pressure.<br />

seismic explosive. It will be delivered in screwableplastic tube which<br />

can be combined to build long loading units.<br />

Gelatine Donarit S is manufactured by the Austin Powder GmbH,<br />

Austria (formerly Dynamit Nobel Wien).<br />

density: 1,6 g/cm3 gas volume: 775 l/kg<br />

specific energy: 971 KJ/kg<br />

velocity of detonation: > 6000 m/s<br />

(without confinement, diameter 32 mm)<br />

Gelatins; Gelatinous <strong>Explosives</strong>; Gelignites<br />

They are dough-like <strong>Explosives</strong> based on nitroglycerine/nitroglycol<br />

gelatinized by nitrocellulose. Gelatine are being replaced by cartridged<br />
