Modeling and rheology of HTPB based composite solid propellants
AbstractThe propellant with the minimum viscosity required for a defect‐free casting can be obtained by proper selection of the size and fractions of solid components leading to maximum packing density. Furnas' model was used to predict the particulate composition for the maximum packing density.

Modeling of diffusion and premixed flame of AP/HTPB laminate propellant [PDF]
Composite propellants feature a diusion §ame. The size of oxidizer particlesleveragesomecombustionproperties(mainly,burningrateand pressure sensitivity) along with §ame structure. Macroscopic combus- tion features are strictly related to those events occurringinside the gas phase and close to the burning surface.

ABSTRACT The objective of this paper is to demonstrate the advantage of computationally pre‐screening surface‐modifying material candidates, using density functional theory (DFT), to inform experimental synthesis and formulation efforts. This demonstration focuses on improving the solubility of benzene‐based materials in hydroxyl‐terminated ...

Influence of time on bond characteristics between extruded PVC tube and cast HTPB/IPDI rocket propellant [PDF]
This paper is dealing about the possibility of using thermoplastic material as an inhibitor for solid composite propellant in a long period of time. A basic point in this consideration is an analysis of bond characteristics between the extruded PVC tube ...

ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.
