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 …

Thermal Conductivity Testing of Minimal Volumes of Energetic Powders
Adam Harris and Daniel N. Sorensen Abstract: Safety constraints have traditionally presented researchers with challenges in testing the thermal conductivity of energetic powdered materials. Minimal volumes of energetic powders can now be tested with the modified transient plane source technique. The newly modified sensor design further reduces the possibility of impact, friction and electrostatic discharge (ESD) …
