The combustion of solid monopropellants and composite propellants
Symposium (International) on Combustion, 1971A model describing the combustion of composite propellants has been applied to three different types of composite propellants, and to two oxidizers which burn as monopropellants. The oxidizers studied are AP, HMX, and KP (ammonium perchlorate, cyclotetramethylenetetranitramine, and potassium perchlorate), each of which has unique combustion ...

8th Joint Propulsion Specialist Conference, 1972
Abstract : The experimental results at 100 bar initial pressure emphasize the importance of the condensed phase properties on the depressurization extinguishment. In all cases of alteration of these properties by the change of binder, the particle size distribution, or the addition of Aluminum the critical depressurization rate for extinguishment was ...

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.

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.

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.

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.

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,

Control of pressure deflagration limits of composite solid propellants
2nd Propulsion Joint Specialist Conference, 1966The pressure below which solid-propellant combustion cannot occur is an important parameter influencing the behavior of extinguishable motors. Permanent extinguishment can be effected by arranging the motor parameters so that no equilibrium chamber pressure is available above this combustion threshold pressure.

Convective ignition of a granular solid propellant bed: Influence of propellant composition
Symposium (International) on Combustion, 1996In previous work, the authors designed and built a laboratory apparatus that subjects a confined bed of granular propellant to essentially a planar hot-gas ignition wave. Diagnostics include wall-mounted pressure transducers to monitor the time history of the pressure field, and fast-response thermocouples protected within custom sting-mounted steel ...
