This book explores the opposed piston (OP) engine, a model of power and simplicity, and provides the first comprehensive description of most opposed piston (OP) engines from 1887 to 2006. Design and performance details of the major types of OP engines in stationary, ground, marine, and aviation applications are explored and their evolution traced. The OP engine has set enviable and leading-edge standards for power/weight refinement, fuel tolerance, fuel efficiency, package space, and manufacturing simplicity. For these reasons, the OP concept still remains of interest for outstanding power and package density, simplicity, and reliability; e.g., aviation and certain military transport requirements. Using material from historic and unpublished internal research reports, the authors present the rationale for OP engines, their diverse architecture, detailed design aspects, performance data, manufacturing details, and leading engineers and applications. Comparisons to four-stroke and competitor engines are made, supporting the case for reconsidering OP engines for certain applications. Topics include: The history of OP engines Aeronautical Automotive Military Marine Unusual OP engines Comparison between 2 and 4 stroke engines The future of OP engines and more
Cranborne Chase, in central southern England, is the area where British field archaeology developed in its modern form. The site of General Pitt Rivers' pioneering excavations in the nineteenth century, Cranborne Chase also provides a microcosm of virtually all the major types of filed monument present in southern England as a whole. Much of the archaeological material has fortuitously survived, offering the fullest chronological cover of any part of the prehistoric British landscape. Martin Green began working in this region in 1968 and was joined by John Barrett and Richard Bradley in 1977 for a fuller programme of survey and excavation that lasted for nearly ten years. In this important study, they apply some of the questions in prehistory to one of the first regions of the country to be studied in such detail. The book is a regional study of long-term change in British prehistory, and contains a unique collection of data. A landmark in the archaeological literature, it will be essential reading for students and scholars of British prehistory and social and historical geography, and also for all those involved with archaeological methods.
