Factorial Analysis of the Influence of Both Water and Oxygen on Extruded Double Base Rocket Propellant Decomposition

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The decomposition mechanisms of double base rocket propellants are well known and reported, but the influence of atmospheric conditions such as water and oxygen is poorly understood. In this work, the influence of water and oxygen on an extruded double base (EDB) rocket propellant aged between 70 and 100°C was examined using heat flow ...

A Constant Trinitrotoluene Equivalence Fit for Blast Wave Position Versus Time Data

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Accurately evaluating accidental or intentional detonation scenarios is essential to ensure their intended effectiveness and/or protect personnel and structures. These evaluations often rely on estimating critical blast effect parameters through reference models, which adapt to different scenarios via key constants.

A Critical Review of Limitations and Challenges in Advancement of HNF as a Green Oxidizer for Composite Solid Propellant Formulations

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Hydrazinium nitroformate (HNF) is a chlorine‐free, high‐energy oxidizer with promising applications in green propulsion systems. This review examines the thermal decomposition, combustion kinetics, flame structure, and behavior of HNF, while critically evaluating the current body of literature.

Throttleable Solid Propellants Through Embedded Shape Memory Alloy and Resistance Wires

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 3, March 2025.
Throttling behavior of expanding propellants ABSTRACT Solid propellants are used in propulsion systems for their high performance, feasibility to manufacture, long shelf life, and ease of storage and handling; however, they are limited by the inability to actively control the burning rate.

Beryllium and Cerium Powders as Potential Activators of Aluminum in TBX Compositions

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 3, March 2025.
The picture shows two pressed TBX charges of 60% RDX, 20% AP and 20% of the corresponding metal (Be or Ce). ABSTRACT The possibility of using beryllium or cerium powders as activators of aluminum in the initial stages of a thermobaric explosion was examined both experimentally and theoretically. The compositions, which were compared, comprised 60% RDX,
