Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made of the relationship of the rates of detonation to the density of the explosive, using nitrocellulose (13.3% N2). The diameters of the charges varied from 20 to 30 mm. The charge casings were made of cellophane. The detonation rates were measured by optical methods using a high-speed photorecorder (SFR). From three to four measurements were made for each value of charge density. The average error of measurement did not exceed 1 - 2%. The lowest charge density value amounted to 0.13 g./cc. This is sufficiently close to the density values at which the detonation products obey the equation of state for ideal gases.

Available in PDF, EPUB and Kindle. Book excerpt: This work marks a stage in the evolution of a scientific and technical field which has been developed by the Commissariat a l'Energie Atomique (CEA) over several decades. Many members of the staff of the CEA have won re nown in this field, and their work has brought it to the high degree of excel lence for which it is internationally recognized today. These scientists had to consider every aspect of the field, as it concerned: modeling, which has recourse to fluid thermodynamics, molecular phys ics, and chemistry; numerical evaluation, which relies on mathematical analysis and data processing; and experiments in the firing area, which require specific stress generators and instrumentation. Whilst this book is a testament to the activity and success of staff of the CEA, it also reviews a number ofthe advances made in the discipline. How ever, it is not intended to be an exhaustive account of those advances; it is assumed that the reader can, if desired, consult the standard monographs, and more recent, more specialized works (notably W.C. Davis and W. Fickett, and C.L. Mader). The history of the discipline is interesting in itself, and also as an illustra tion of the causes which lead to progress in a coherent body of scientific work. I should like to make some comments on this progress, of which there is a fascinating summary in the introduction, and which will figure largely throughout the work.

Available in PDF, EPUB and Kindle. Book excerpt: It is of definite importance to measure the velocity of detonation of condensed explosives with a charge having a low density, where the products of the explosion are not governed by the equation of the state of ideal gases, but the elastic component of the pressure is small compared to the total pressure. To this zone correspond pressures resulting from a detonation of explosives whose density is less than 0.8 grams/cubic centimeter. In the majority of cases, however, the lower value of the density at which the detonation velocity of explosives is determined amounts to 0.5-0.6 grams/cubic centimeter. It is a fact that it is difficult to determine the detonation velocity of the majority of explosives at lower densities. In this work, the relationship between the detonation velocity and the density of explosives was investigated by using nitrocellulose (13.3% N2) which can provide charges of low density. Because the detonation velocity of nitrocellulose was not measured before, tests included a wide range of densities of the charge. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: It is known that the Chapman-Jouguet theory of detonation is based on the assumption of an instantaneous and complete transformation of explosives into detonation products in the wave front. Therefore, one should not expect from the theory any interpretations of the detonation limits, such as shock initiation of det onation and kinetic instability and propagation (failure diameter). The Zeldovich-Von Neuman-Doring (ZND) theory of detonation appeared, in fact, as a response to the need for a theory capable of interpreting such limits, and the ZND detonation theory gave qualitative interpretations to the detonation limits. These interpretations were based essentially on the theoretical notion that the mechanism of explosives transformation at detonation is a combustion of a layer of finite thickness of shock-compressed explosive behind the wave shock front with the velocity of the front. However, some experimental findings turned out to be inconsistent with the the ory. A very small change of homogeneous (liquid) explosives detonation velocity with explosive charge diameter near the rather sizable failure diameter is one of the findings. The elucidation of the nature of this finding has led to the discovery of a new phenomenon. This phenomenon has come to be known as the breakdown (BD) of the explosive self-ignition behind the front of shock waves under the effect of rarefaction waves.
