Georg Steinhauser, Karina Tarantik and Thomas M. Klapötke Abstract: Copper compounds play a key role in the development of “greener” pyrotechnics by substitution of noxious barium compounds from green colored effects. The application of many copper(ii) compounds in pyrotechnics is limited because of their noble and often hygroscopic character. We have investigated nitratocuprates(ii) as well …

Thermal Stability of Hydrazinium Nitroformate (HNF) Assessed by Heat Generation Rate and Heat Generation and Mass Loss
Manfred A. Bohn Abstract: HNF, hydrazinium nitroformate, H3NNH2 +·C(NO2)3−, is a water soluble salt. It has a positive oxygen balance of 13%, a much more positive enthalpy of formation than ammonium perchlorate (AP) and amuch higher heat of explosion than AP, 5579 J g−1 against 1972 J g−1. Additionally it has no chlorine and all …

Synthesis, Structural and Reactive Characterization of Miscellaneous Nanothermites
Denis Spitzer and Marc Comet Abstract: In this paper, we report the elaboration and the characterization of several kinds of nanothermites made at the French German Research Institute of Saint‑Louis (ISL). Three types of materials are presented herein: tungsten trioxide based nanothermites obtained by physical mixing of this metallic oxide withaluminum nanoparticles; tungsten trioxide based …

Laser Diode Ignition of Pyrotechnic Mixtures: Experimental and Numerical Studies
Pr Philippe Gillard Abstract: An experimental study of laser ignition of Zr/KClO4, Zr/PbCrO4, Fe/KClO4, Fe/KNO3, B/KClO4 and B/KNO3 mixtures is presented in this paper. The ignition system is composed of two lenses which focus the laser beam on the tablet. A sapphire porthole, juxtaposed with the pyrotechnic composition, protects the optical unit but causes losses …

Ignition And Burning Rate Characteristics Of Pyrolant Black Powder
Takuo Kuwahara Abstract: Composite propellants contain binder as fuel which connects oxidizer particles and metals. The burning rate of a propellant is affected by the concentration and type of binder. Pyrolant is mixed with oxidizer particles and metal particles. Pyrolant does not contain binder, so burns smoothly. The burning rate of black powder (BP) which …

Ignition and Combustion of Aluminium in High Explosives
Arno Hahma Abstract: Ignition and combustion properties of aluminium powder up to 250 kbar pressure were successfully determined. Hydrodynamic modelling combined with parametrized reaction profiles was used to match the experimental metal plate profiles to calculated values and the metal reactivity was determined from the parameters thus obtained. The reaction profiles over a wide range …

Atmospheric Flight Dynamic Simulation Modeling Of Spin-Stabilized Projectiles And Small Bullets With Constant Aerodynamic Coefficients
Dimitrios N. Gkritzapis, EliasE. Panagiotopoulos, Dionissios P.Margarisb and Dimitrios G.Papanikas Abstract: A full six degrees of freedom (6-DOF) simulation flight dynamics model is applied for the accurate prediction of short and long range trajectories of high and low spin-stabilized projectiles and small bullets via atmospheric flight to final impact point. The projectile is assumed to …
