Composite solid propellants were prepared with and without nano-alloys (Ti-Co, Ti-Ni, Ti-Zn), where nano-alloys used as catalyst. These nano-alloys are prepared by hydrazine reduction method. Catalytic properties of these nanomaterials were measured on Ammonium perchorate/hydroxyterminatedpolybutadiene propellant by thermogravimetery analysis and differential thermal analysis. Both experimental...

Rotating detonation combustors (RDCs) are among the that use supersonic combustion waves known as waves, and expected to simplify engine systems improve thermal efficiency due their compression performance using shock waves. Research is also being actively conducted worldwide on a cylindrical RDC; RDC without an inner cylinder, which downsize combustor. However, most of research was performed g...

A numerical framework based on the generalized finite element method (GFEM) is developed to capture the coupled effects of thermomechanical deformations and thermal gradients on the regression rate of a heterogeneous solid propellant. The thermomechanical formulation is based on a multiplicative split of the deformation gradient and regression of the heterogeneous solid propellant is simulated ...

A mullite-supported Rh catalyst with an unusual crystalline structure in favour of high-temperature reactions was applied for the first time to the catalytic decomposition of N(2)O propellants, and has shown a promising initial activity and thermal stability.

Energy density, which is an important indicator of the performance solid propellants, known to increase with addition 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20). However, it remains unclear how CL-20 affects decomposition ammonium perchlorate (AP) and energy release. Here, effects on combustion agglomeration propellants were investigated. The decreased AP temperature req...
