Helicopter Design & Data Manual - 1973

Everything you need to know in order to design, build, and fly your own helicopter! "The primary purpose of this book is education — for the student, the designer, and the individual whose interest and aim is to design and build his own helicopter. The material selected for presentation has been carefully prepared to give the reader a basic understanding of the requirements of helicopter design. During the past ten years I have noted with great concern the growing interest of individuals in designing and building their own helicopters, with a variety of configurations, but with only a relatively minor degree of success. Individuals contemplating a helicopter "design-build" project should consider devoting ample time to familiarizing themselves with the basic fundamental of helicopter aerodynamics, structures, mechanics, and the selection of aircraft quality materials. These areas of study are recommended as the basic criteria with which to become fully acquainted. Application of theory, principles and processes are the major factors involved..." - Helicopter Design & Data Manual - S.J. Dzik, 2nd Ed.
