This work Rotorcraft, covers the various types of rotorcraft including helicopters, gyrocopters, proprotors and tiltrotors rotors, etc, both civilian and military. The first chapter is devoted to the development of rotorcraft from the days of the first flights of helicopter pioneers such as Juan de la Cierva, Paul Corno, Harold F. Pitcairn and Igor Sikorsky, to name a few. The second chapter of Rotorcraft, covers the various types of helicopters identified by their main and anti-torque rotor systems, how helicopters and gyrocopters fly and the similarities and differences between the two types. Helicopter manufacturers from the past to the present are included. The remainder of the book details a selection of 126 individual rotorcraft types, including at least one photograph, technical performance data and a short history of the type. An Appendix of rotorcraft facts completes this work. New rotorcraft are continuously being designed and built. Several various types of rotorcraft are presented here to build up a fascinating collection within these pages which, I trust the reader will find of great value and interest.
