Gap parameter γ between AP particles is proposed for viscoelasticity analysis in AP/HTPB composite propellant slurry. The particle-gap of γ = 0.5 was a threshold of shape-retaining in KCl/HTPB simulated propellant slurry consisting of monomodal particles, and the slurry viscoelasticity increased by over 5 times with a slight narrowing of the particle-gap at around γ = 0.5. The slurry showed the similar property also in the case of the different HTPB viscosity and KCl particle-diameter. These results suggest that the viscoelasticity of the dense slurry strongly depends on the particle-gap of the particulate structures. [ABSTRACT FROM AUTHOR] |
