cze Detonační charakteristiky plastických výbušin na bázi atraktivních nitraminů, pojených polyisobutylenovými a poly(methylakrlátovými) pojivy. Čtyři vysoce brisant nitraminy, RDX (1,3,5-trinitro-1,3,5-triazinan), HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazocan), BCHMX (cis-1,3,4,6-tetranitro-oktahydroimidazo-[4,5-d]imidazol) a epsilon-HNIW(epsilon-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitan), byly studovány jako extrudované plastické výbušniny pojené polyizobutylénovým plastem (C4 matice) a poly methylmetakrylátovým pojivem (plastifikovaný dioktyl-adipátem). Detonační rychlosti, D, byly experimentálně měřeny. Detonační parametry byly vypočteny také metodu Kamlet a Jacobs a dále CHEETAH a EXPLO5 kódy. Tyto parametry detonace ukázaly, že plasty pojené trhaviny na bázi BCHMX jsou výbušninami výkonnějšími než tytéž na bázi RDX. Urizarovy koeficienty pro poly(methyl methacrylate) pojiva byly také počítány. BCHMX; detonace; HMX; HNIW; nitraminy; plastické trhaviny; RDX
eng Detonation characteristics of plastic explosives based on attractive nitramines with polyisobutylene and poly(methyl methacrylate)binders. Four highly brisant nitramines, RDX (1,3,5-trinitro-1,3,5-triazinane), HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazocane), BCHMX (cis-1,3,4,6-tetranitro-octahydroimidazo[4,5-d]imidazole), and epsilon-HNIW(epsilon-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane), were studied as extruded plastic explosives bonded by two plastic matrices based on polyisobutylene (C4 matrix) and poly-methylmethacrylate (plasticized by dioctyl-adipate) binders. The detonation velocities, D, were measured experimentally. Detonation parameters were also calculated by means of the Kamlet and Jacobs method and CHEETAH and EXPLO5 codes. These detonation parameters showed that plastic-bonded explosives (PBXs) based on BCHMX are more powerful explosives than those based on RDX. The Urizar coefficient for poly(methyl methacrylate) binder was also calculated. BCHMX; detonation; HMX; HNIW; nitramines; plastic explosives; RDX
