Book Description
Theoretical analysis and experimental measurements are defined for the investigation of high pressure combustion of solid propellants in ballistic devices. A new and accurate heat flux measurement technique is used for determination of the equation of state for the propellant gas. A method of determining the burning rate for the solid propellant from the closed chamber tests is described. The interior ballistic theory is reviewed in the context of a high pressure combustion device. Design and instrumentation of the closed chamber test apparatus for the equation of state and the burning rate measurements are included. An open ballistic chamber test apparatus with a moving projectile, for measurement of projectile friction and for verification of the interior ballistic performance at high chamber pressures is described. (Author).

Book Description
The report is largely a restatement of conclusions, with reference to previous publications for details. The areas of study reported are an evaluation of the hot-wire-ignition method for characterizing propellants; the development and study of a gas-fueled analog of the solid-propellant T-burner; a study of low frequency (L*) combustion of L* during a test; a study of high frequency acoustic instability of solid propellants, both a T-burner and a radial-mode, radial-flow burner being used with the same propellants systems; the development and evaluation of a technique for measuring the solid-propellant response function to external energy perturbations at the burning surface; the measurement and evaluation of transient temperatures of propellant flames during rapid depressurization; and a detailed characterization of the low-pressure-combustion phenomena for several different solid propellants including studies of the low-pressure deflagration limit, the electrical conductance near the surface, the extinguishment requirements, and spontaneous reignition.

Book Description
This third edition of the classic on the thermochemical aspects of the combustion of propellants and explosives is completely revised and updated and now includes a section on green propellants and offers an up-to-date view of the thermochemical aspects of combustion and corresponding applications. Clearly structured, the first half of the book presents an introduction to pyrodynamics, describing fundamental aspects of the combustion of energetic materials, while the second part highlights applications of energetic materials, such as propellants, explosives and pyrolants, with a focus on the phenomena occurring in rocket motors. Finally, an appendix gives a brief overview of the fundamentals of aerodynamics and heat transfer, which is a prerequisite for the study of pyrodynamics. A detailed reference for readers interested in rocketry or explosives technology.

Book Description
Nonmetallized double-base and composite propellant, metallized composite propellant, and ammonium perchlorate (AP)/binder sandwich combustion were studied in standard and high acceleration environments. Experimental techniques used were high speed motion pictures, tow-color schlieren, laser schlieren, and centrifuge mounted combustion bombs. It was found for double-base propellant that the temperature increased continuously from the surface into the visible flame. Acceleration induced burning rate augmentation occurred and resulted in elimination of the visible flame. Acceleration apparently modified the surface or subsurface zones. AP/binder sandwich combustion was also found to be acceleration sensitive with binder flow-AP interactions proposed as the mechanism. Composite propellants burned with local diffusion flames to pressures as slow as 100 psi. A comparison is made between AP/binder sandwich combustion and propellant combustion. (Author).
