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.

โฆ Synopsis
A composite propellant subjected to radiant heating at the surface is theoretically investigated. Numerical solutions of the mathematical model which considers ignition as due to runaway chemical reactions at the propellant surface or in the adjacent gas-phase indicate that although inclusion of the surface reactions alter the ignition behavior slightly, the process is dominated by gas-phase reactions.

The ignition of composite solid propellants by CO 2 laser irradiation at low pressures has been investigated experimentally. Three ignition modes are found at subalJnospheric pressures: self-sustaining ignition, non-self-sustaining ignition, and pulsating ignition. Here, the self-sustaining and the
Ignition times of phenol-formaldehyde composite propellants having a variety of oxidizers and additives have been measured by a hot plate technique. The data have been used to compute the activation energy of the ignition process. These studies indicate the possibility that different mechanisms may
Time-dependent processes of solid propellant deflagration are modeled and a numerical simulation of ignition and extinction is undertaken. Since the analytic theory of ignition is well developed we rely on it to verify the ability of the numerical algorithm to track stiff, time-dependent features of
During the thermal decomposition of orthorhombic ammonium perchlorate (AP) at 230"C, where the decomposition is only up to 30 wt %, there is an accumulation in the solid of acids, the concentration of which increases up to 15% decomposition, after which it decreases till it reaches the original valu
