Coating of High Melting Explosive Particles by Nitrotriazolone to Formulate Composite Nanoparticles by Spray Flash Evaporation

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 32-39, December 2025.
ABSTRACT The balance between performance and safety of high explosives is at the heart of the current studies, and new ways of combining safety and performance have hence been elaborated. This study focuses on a mixture of 3‐nitro‐1,2,4‐triazol‐5‐one (NTO) and octogen (high melting explosive [HMX]).

Thermo‐Mechanical Evaluation of Novel Composite Propellant Formulations Based on Styrene‐Ethylene/Butylene‐Styrene Block Copolymer

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 117-126, December 2025.
ABSTRACT Two novel composite propellant formulations have previously been produced from a binder consisting of the thermoplastic elastomer styrene‐ethylene/butylene‐styrene (SEBS) and a solid filler, either ammonium perchlorate (AP) or 1,3,5‐trinitro‐1,3,5‐triazinane (RDX).

Strength criterion of composite solid propellants under dynamic loading

Defence Technology, 2018
Based on the dynamic loading (1-100 s−1) experiments under different temperatures (223–298 K) and stress states, uniaxial and biaxial strength criterion of a Hydroxyl-terminated polybutadiene (HTPB) based composite solid propellant were further ...

Analysis of pressure blips in aft-finocyl solid rocket motor [PDF]

, 2016
Ballistic anomalies have frequently occurred during the firing of several solid rocket motors (SRMs) (Inertial Upper Stage, Space Shuttle Redesigned SRM (RSRM) and Titan IV SRM Upgrade (SRMU)), producing even relevant and unexpected variations of the SRM

A Structural Integrity Perspective for the Assessment of Ageing in Composite Solid Propellants

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 10, Page 152-158, October 2025.
ABSTRACT Composite solid propellants (CSPs) are critical materials in the defence and aerospace industries, known for their complex mechanical behaviour and susceptibility to ageing. This study explores the application of Principal Component Analysis (PCA) to discriminate the ageing degradation of CSPs based on structural integrity parameters.

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

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 7, Page 11-30, July 2025.
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.

Synthesis of propellant grade HHTPB by hydrogenation of HTPB using Pd-activated charcoal as catalyst

FirePhysChem
To derive more performance from the conventional composite propellant based on hydroxyl-terminated polybutadiene (HTPB) and ammonium perchlorate (AP), it is envisaged to hydrogenate HTPB, which increases the H/C (hydrogen to carbon ratio) of the base ...

Moisture And Temperature Ageing On htpb Based Propellants Binder

Macromolecular Symposia, Volume 414, Issue 3, June 2025.
Abstract This study reports the impact of temperature, oxygen, and humidity ageing on the mechanical properties of a crosslinked hydroxy‐terminated polybutadiene (HTPB) network. Its mechanical behavior is described using a classical Mooney‐Rivlin model and shows a slight crosslinking reaction possibly due to oxidation of HTPB.
