Modeling Composite Solid Propellant with Catalytic Additives
51st AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2013This paper presents current work on improving the accuracy of solid composite propellant modeling to include catalytic additives and using it to develop a better understanding of the working mechanism of burning rate enhancement. To this end, isolating the physical mechanism where the catalyst impacts the composite propellant burning rate was studied ...

Viscosity Prediction of Composite Solid Propellant Slurry
Propellants, Explosives, Pyrotechnics, 1986AbstractThe viscosity of composite solid propellant slurry is an important parameter in charging technical performance of solid rocket motors. It is affected not only by the liquid phase ingredients of propellants, but also by the size, content, shape and surface properties of solid fillers in propellants.

Nanomaterials as modifier for composite solid propellants
Nano-Structures & Nano-Objects, 2019Abstract Propellants are the major source of chemical energy in space vehicles and missiles. The AP (Ammonium perchlorate), AN (Ammonium nitrate), RDX (Hexahydro-1, 3, 5-trinitri-1, 3, 5-triazine) and HMX (Octahydro-1, 3, 5, 7-tetranitro-1, 3, 5, 7- tetrazocine), etc are currently the most widely used energetic materials in composite solid ...

Some properties of a composite solid propellant.
2009Temperature profiles during polymerization, for the infinite solid cylinder, the infinite hollow cylinder and the star perforated infinite cylinder of polyurethane ammonium perchlorate solid propellent, have been determined. They show that the temperature across the solid rises considerably above the wall temperature and exceeds the 60°C (140°F) limit,

Erosive Burning of Some Composite Solid Propellants
Journal of Jet Propulsion, 1954Experimental data on the erosive burning of several composite solid propellants are reported and discussed. The data appear to be best correlated in terms of a reduced mass velocity. At low Mach numbers , th is correlation becomes equivalent to several widely used forms employing linear velocity.

Composite solid-propellant ignition by radiant energy
AIAA Journal, 1970Ignition characteristics of representative composite solid propellants were studied using an arc-imaging furnace to provide a radiant energy source. The variation of propellant ignitability with formulation changes was found to be small provided the binder and oxidizer were fixed. The minimum initial pressure for which ignition will occur appears to be

Aluminum agglomeration in composite solid propellants combustion
Journal de Physique IV (Proceedings), 2002The model of metal agglomeration in CSP combustion has been developed. The Monte Carlo (MC) method for simulation of aluminum agglomeration is considered. The investigation of different agglomeration mechanisms by the MC method has been fulfilled. It is demonstrated,'that agglomerates spectra, calculated by the MC method are polymodal, which correlates

Non-Steady Combustion of Composite Solid Propellants.
1984Abstract : An analytical model for the linearized velocity-coupled combustion response function was developed. The model combines elements of response to velocity perturbations, pressure perturbations, and compositional perturbations due to the heterogeneity of composite propellants.
