203 Liquid Propellants<br />

explosive strength of these mixtures is very high. However, since the<br />

components are corrosive, their handling is very unpleasant; when<br />

mixed together, the product becomes highly sensitive. For all these<br />

reasons they are no longer employed in practice.<br />

For mud-like ammonium nitrate explosives W Slurries and W Emulsion<br />

Slurries.<br />

Liquid Oxygen <strong>Explosives</strong><br />

Flüssigluft-Sprengstoffe; Oxyliquit;<br />

explosifs à l’oxygène liquide<br />

Liquid oxygen explosives are made by impregnating cartridges made<br />

of combustible absorbent materials such as wood dust, cork meal,<br />

peat dust, W Carbene, etc., with liquid oxygen. They must be exploded<br />

immediately after the impregnation and loading, which are carried out<br />

in situ. They are energy-rich and cheap, but their manner of utilization<br />

does not permit rational working, such as detonating a large number of<br />

charges in one priming circuit. They are, accordingly, hardly ever<br />

employed in practice.<br />

Liquid Propellants<br />

Flüssigtreibstoffe; propergols liquides;<br />

(Monergol; Hypergolic)<br />

Combinations of pairs of liquids which react with each other (fuels and<br />

oxidizers in the most general sense of the word) which release energy<br />

in the form of hot gaseous reaction products; the W Gas Jet Velocity<br />

builds up the W Thrust. The caloric yield and the possible magnitude of<br />

the specific impulse may be higher than in one-component systems –<br />

i. e., higher than those of W Monergols, homogeneous propellants,<br />

and composite propellants.<br />

Examples of fuels are alcohol, hydrocarbons, aniline, hydrazine, dimethylhydrazine,<br />

liquid hydrogen, liquid ammonia.<br />

Examples of oxidizers are liquid oxygen, nitric acid, concentrated<br />

H2O2, N2O4, liquid fluorine, nitrogen trifluoride, chlorine trifluoride.<br />

Certain pairs of the reacting liquids are W Hypergolic.<br />

The liquid-propellant technique was developed for rocketry, but it is<br />

also considered today for small caliber cannons (e.g. 30 mm P).
