Combustion of a Composite Solid Propellant with Addition of Boron Powder
Combustion, Explosion, and Shock Waves, 2022 A conjugated physical and mathematical model for the combustion of a composite solid propellant with addition of a polydisperse boron powder is presented. This model accounts for gas-dynamic processes in a two-phase, multi-rate, and multi-temperature heat-conducting medium, as well as heat transfer and reaction processes in solid propellant are taken ...

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 ...

Detonability of Solid Composite Propellants
ARS Journal, 1961The thin film pla t inum resistance thermometer (heat flux gage) has been successfully applied to measurement of heat fluxes from initiators for solid propellants. Hea t fluxes measured were as high as 1000 Btu/ft-sec from hot, particleladen reaction products of pyrotechnic igniters.

Numerical Simulation of Combustion of a Composite Solid Propellant Containing Boron Powder
Combustion, Explosion and Shock Waves, 2022 The combustion of a metallized composite solid propellant containing boron particles is numerically studied. The mathematical model is based on the approaches of two-phase reacting medium mechanics for describing processes in a two-phase flow above the ...

Nano-composites for rocket solid propellants
Composites Science and Technology, 2005Aim of this work is the study of different components (binder and aluminum powders) of solid propellants used for rocket propulsion to improve ballistic performance. New propellant formulations have been tested and characterised. Combustion residues were collected by a proprietary method and analyzed both from the morphological and chemical point of ...

Oscillatory burning of solid composite propellants
Symposium (International) on Combustion, 1963Analytical consideration of the interaction of an oscillatory pressure disturbance with the burning zone of a composite propellant leads to the conclusion that acoustic waves induce periodic variations in the ratio of the mass release rates of composite propellant components that give rise to harmonic composition and adiabatic flame temperature ...

Combustion mechanisms of composite solid propellants
Symposium (International) on Combustion, 1977By means of theoretical modeling as well as by the experimental investigation of various propellants, further elements are presented to consolidate the understanding of the combustion of ammonium perchlorate propellants. Available descriptions of A.P. combustion, binder pyrolysis and composite propellant combustion are presented and compared favorably ...
