The journals of a Battle of Britain Pilot. Tony Bartley epitomised the young, dashing fighter pilot of the Battle of Britain. Born in Ireland but educated in England, he joined the RAF at the outbreak of war. He flew Spitfires with 92 Squadron from RAF Hornchurch, first in the battle of France, then covering the Dunkirk evacuation. Later in 1940 he moved to RAF Biggin hill and flew daily over London at the height of the Battle of Britain. Bartley went on to test-fly Spitfires, them led 65 Squadron, then 111 Squadron in North Africa and also flew with the American 9th Air Force covering the Normandy landings. His account relives the close atmosphere of close knit fighter squadrons and also the respite offered by the London social life. He met and married the actress Deborah Kerr and moved to Hollywood where he became a screen-writer and later a film company executive.
Smoke trails are used to find winds in the upper atmosphere. In the present paper, a theoretical study is conducted of the motion of smoke trails in winds of constant shear in the case of potential, vorticity, and stratified flows. Some general considerations of the motion of smoke trails are also given. (Author).
This book examines blast waves—their methods of generation, their propagation in several dimensions through the real atmosphere and layered gases, and their interactions with simple structures—thereby providing a broad overview of the field. The intended audience has a basic knowledge of algebra and a good grasp of the concepts of conservation of mass and energy. The text includes an introduction to blast wave terminology and conservation laws, and there is a discussion of units and the importance of consistency. This new edition of Blast Waves has been thoroughly updated and includes two new chapters that cover numerical hydrodynamics and blast injury. Authored by an expert with over forty years of experience in the field of blast and shock, this book offers many lessons as well as a historical perspective on developments in the field.
Propellants and Explosives Explosives and propellants are termed energetic materials for containing considerable chemical energy which can be converted into rapid expansion. In contrast to simple burning of a fuel, explosives and propellants are self-contained and do not need external supply of oxygen via air. Since their energy content thus inherently creates the risk of accidental triggering of the explosive reaction, proper synthesis, formulation, and handling during production and use are of utmost importance for safety and necessitate specialist knowledge on energetic materials, their characteristics, handling, and applications. Now in its third edition, the classic on the thermochemical aspects of the combustion of propellants and explosives is completely revised and updated and includes green propellants as new topic. The combustion processes of typical energetic crystalline and polymeric materials and various types of propellants and pyrolants are presented to provide an informative, generalized approach for the understanding of the combustion mechanisms of those materials. The first half of the book represents an introductory text on pyrodynamics, describing fundamental aspects of the combustion of energetic materials. The second half highlights applications of energetic materials as propellants, explosives and pyrolants with focus on phenomena occurring in rocket motors. In addition, the 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.
