Abstract : The purpose of this work is to study the dynamic behavior in the combustion of three types of propellants used in artillery systems. Theses propellants include very high burning rate (VHBR), low vulnerability ammunition (LOVA), and programmed splitting stick (PSS) propellants. Several advanced nonintrusive diagnostic instruments were utilized in this study. These instruments include: a real-time X-ray radiography system, a digital image processing system, a multi-channel laser doppler velocimeter, and high-speed movie cameras. A shock tunnel and a high-powered CO2 laser were also employed for this investigation. This research project was divided into three major areas: (a) combustion behavior of VHBR propellants; (b) convective and radiative ignition processes of LOVA propellants; and (c) combustion and segregation phenomena of PSS propellants. The research motivation, program objectives, method of approach, results, and summary and conclusions of each are given in Chapters 1,2, and 3, respectively. Results obtained from this study not only enhance the basic understanding of the complex phenomena and controlling mechanisms associated with ignition, combustion, and mechanical deformation of these propellants but also helps the design of future artillery systems with minimum hazards.
