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 ...

Calorimetric values of composite solid propellants
Thermochimica Acta, 1982The calorimetric values of composite solid propellant based on polystyrene, polyphenolformaldehyde, poly(vinyl chloride) and carboxy-terminated polybutadiene were determined using combustion calorimetry in order to assess the uncertainities in their measurements.

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 of composite solid rocket propellants.
AIAA Journal, 1969CONSIDERABLE work has been done on solid rocket ^->< propellants using various fuels (often polymers) and oxidizers. Recently Rastogi and Ouseph have studied the combustion of phenol-f ormaldehy de/NH 4C10 4 system . They observed that the rate of burning decreases as the amount of cross-linking increases in the polymer.

Ignition delay of composite solid propellants
Combustion and Flame, 1977Abstract Ignition delay of phenol-formaldehyde composite propellants was measured by a hot plate technique. The activation energy for the preignition reactions has been computed using the Arrhenius type expression for ignition delay.

Burning rate catalysts for composite solid propellants
Combustion and Flame, 1977The combustion of composite solid propellants was studied using ammonium dichromate, chromium carbonate, chromium oxide, basic copper carbonate and cupric oxide as additives. Burning rates were considerably enhanced in each case. Flame temperatures were measured and found to be higher than in cases where additives were not used.

Erosive burning of composite solid propellants
Combustion and Flame, 1966A model is proposed for erosive burning of ammonium perchlorate composite wolid propellants. It is assumed that combustion takes place in the turbulent boundary layer and that the turbulent flame consists of distorted ‘flamelets’ but otherwise retains on a molecular scale the characteristics of a laminar flame.

Some Experiments on Model Composite Solid Propellants
Propellants, Explosives, Pyrotechnics, 1983AbstractExperiments on two‐dimensional model propellants using cylindrical oxidizer (ammonium perchlorate) pellets in a fuel matrix (CTPB) are described. Measurements show that burning rate of AP in the fuel environment is lower than of pure AP. The oxidizer‐to‐fuel ratio seems to be fuel‐rich when the oxidizer particles are imbedded in contact with ...
