ADN

EURENCO is equipped with a pilot-scale production of crystalline ADN. Milled (fine fraction) crystals and Prilled (spherical particles) could be supplied. Milled and Prilled ADN products are normally supplied with anti-caking agent.

Smokeless propulsion of missiles has a great military value. It is a serious tactical drawback if the signature from the propellant will guide the enemy to the launching site of a rocket weapon.

ADN is a new oxidant that burns without secondary smoke and provides a higher impulse, compared with ammonium perchlorate (AP) for instance. Its performance can be compared to CL-20 and HNF, with lower prices.

Due to these characteristics, AND can be used as:

• A potential replacement for AP in composite rocket motor propellants, for surface-to-air and air-to-air missiles and space shuttles;
• A liquid mono propellant for rocket motors in replacement of hydrazine, for rocket motors used in spacecraft propulsion (non-carcinogenic, higher performance, reduced risks and costs);
• An oxidizer and high explosive in depth charges, such as underwater ammunition (torpedoes, underwater mines, etc.): ADN, combined with Al, has shown to outperform compositions of AP/RDX/Al type in terms of higher bubble energies for depth charges.
