Effect of Mechanical Heterogeneity on the Structural Integrity of HTPB Propellant Grain

Materials, 2023
To investigate the structural effects of the mechanical heterogeneity of Hydroxyl-terminated polybutadiene (HTPB) propellant grain under ignition pressurization, a gradient finite element method was proposed to evaluate its structural integrity. The heterogeneous mechanical properties of the propellant grain were constructed and assessed.

Modeling of diffusion and premixed flame of AP/HTPB laminate propellant [PDF]

Progress in Propulsion Physics, 2009
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.

Research on microscopic structure–activity relationship of AP particle–matrix interface in HTPB propellant

e-Polymers
The matrix and particle interface of hydroxyl-terminated polybutadiene (HTPB) propellant is the weakest part of its mechanical properties, making it prone to dewetting damage and destroying the structural integrity of the propellant.
