Abstract

Fizika brzih, jakih udara i balistika imaju široku primjenu u vojnom području, pri
proučavanju udara meteora; novih pogona za vozila, letjelica, raketa i bojevih glava, fuzije,
te pri istraživanju ostalih udarnih pojava. Opisivanje ponašanja materijala izloženih
djelovanju visokih tlakova i uzrokovanih naprezanja, složeno je multidisciplinarno
područje koje uključuje mehaniku, termodinamiku, hidrodinamiku i kemiju. Ubrzanje
projektila, za potrebe metoda mjerenja distribucija brzina tijekom leta i neposredno prije
udara, moguće je postići ubrzivačima s eksplozivnim nabojima. U radu je dan pregled
postojećih metoda mjerenja brzina projektila te opis metode razvijane unutar Laboratorija
za ispitivanje eksplozivnih tvari Rudarsko-geološko-naftnog fakulteta.

Abstract (english)

Abstract: Physics of fast, strong impacts and ballistics has a wide range of application in military
use, research of meteor impacts, fusion, new propulsions and all other impact phenomena.
Describing of material behavior which are exposed to high pressure and associated strain
is a complex multidisciplinary field which includes mechanics, thermodynamics,
hydromechanics and chemistry. Acceleration of projectiles, for the methods needs of
measuring velocity distribution during the flight and just before impact, is achievable with
explosive accelerators. The paper gives an overview of existing methods for measuring
projectile velocity and description of method developed within Laboratory of testing
explosive materials on the Faculty of mining, geology and petroleum engineering.
