Fenomen erozije cevi naoružanja / Gun barrel erosion

open access: yesVojnotehnički Glasnik, 2009
U radu su prikazana dosadašnja istraživanja erozije cevi. Trošenje cevi je neizbežan proces do kojeg dolazi pri svakom opaljenju. Erozija cevi može se definisati kao progresivna povreda ili oštećenje površine cevi i proširenje kalibra usled opaljenja ...

Thermochemistry of Combustion in Polyvinyl Alcohol + Hydroxylammonium Nitrate

open access: yesAerospace, 2021
A mixture of polyvinyl alcohol (PVA) and hydroxylammoniun nitrate (HAN) forms a gummy solid known as a plastisol, which is ionically conducting. When an electrostatic potential of 200 V DC is applied across the plastisol, it ignites.
