An extremely practical overview of V/STOL (vertical/short takeoff and landing) aerodynamics, this volume offers a presentation of general theoretical and applied aerodynamic principles, covering propeller and helicopter rotor theory for both the static and forward flight cases. Both a text for students and a reference for professionals, the book can be used for advanced undergraduate or graduate courses. Numerous detailed figures, plus exercises. 1967 edition. Preface. Appendix. Index.

Over the past eight decades, developments in vertical lift aircraft--both helicopters and vertical/short takeoff and landing (V/STOL) planes--have given the American military unparalleled capabilities on the modern battlefield. The U.S. has led the world in vertical lift technologies with the help of some of the brightest minds in this field--Igor I. Sikorsky, Arthur M. Young, Frank N. Piasecki, Charles H. Kaman and Stanley Hiller, Jr., to name a few--and by having the industrial prowess to make their concepts reality. This book provides a concise historical survey, including technical specifications, drawings, and photographs of every type of helicopter and V/STOL aircraft developed for the U.S. military, from the earliest examples tested in 1941 and 1942, up to the newest prototypes.

Annotation This text presents the principles of dynamics and control for vertical, short take-off landing (V/STOL) aircraft. It is the first book of its kind. It is intended for graduate students and professionals in aeronautics who have knowledge of linear systems analysis, aircraft static, dynamic stability, and control. The text begins with a discussion of V/STOL aircraft operations. Control strategies, equations of motion, longitudinal and lateral-directional flying qualities in both hover and forward flight, wind and turbulence responses, and control augmentation and cockpit displays are covered. Specific examples of the YAV-8B Harrier and XV-15 Tilt Rotor aircraft are used to illustrate actual V/STOL dynamic and control characteristics.

Small Format Aerial Photography and UAS Imagery: Principles, Techniques and Geoscience Applications, Second Edition, provides basic and advanced principles and techniques for Small Format Aerial Photography (SFAP), focusing on manned and unmanned aerial systems, including drones, kites, blimps, powered paragliders, and fixed wing and copter SFAP. The authors focus on everything from digital image processing and interpretation of data, to travel and setup for the best result, making this a comprehensive guide for any user. Nine case studies in a variety of environments, including gullies, high altitudes, wetlands and recreational architecture are included to enhance learning. This new edition includes small unmanned aerial systems (UAS) and discusses changes in legal practices across the globe. In addition, the book presents the history of SFAP, providing background and context for new developments. - Provides background and context for new developments in SFAP - Covers the legal implications for small format aerial systems in different countries - Discusses unmanned aerial systems (drones) and their applications - Features new case studies for different applications, including vineyard monitoring and impacts of wind energy

FREAX – the biggest book ever written about the history of the computer demoscene. The book tells the complete history of the Commodore 64 and the Amiga, both about the machines and about the underground subcultures around them, from the cracker- and warez-scene to the demoscene, from hacking and phreaking to the ASCII art scene. Interviews with scene celebrities, former key persons of the computer industry, citations from contemporary magazines and fanzines make the narrative history of the big adventure complete. The book contains 350 pages and is illustrated with 480 color photos and screenshots. This is the comprehensive guide to the golden era of home computers.
