Wayne Johnson worked at the U.S. Army Aeromechanics Laboratory from 1970 to 1981 at the NASA Ames Research Center. He was with NASA from 1981 to 1986, including a couple of years as Assistant Branch Chief. Dr Johnson founded Johnson Aeronautics in 1986, under which he developed rotorcraft software until 1998. Since 1998, he has worked at the Aeromechanics Branch of NASA Ames Research Center. Dr Johnson is author of the comprehensive analysis CAMRADII and the rotorcraft design code NDARC; and of the book Helicopter Theory (1990). He is a Fellow of the American Institute of Aeronautics and Astronautics (AIAA) and the American Helicopter Society (AHS) and has received a U.S. Army Commander's Award for Civilian Service, NASA Medals for Exceptional Engineering Achievement and Exceptional Technology Achievement, the AHS Grover E. Bell Award, the Ames H. Julian Allen Award, the AIAA Pendray Aerospace Literature Award and the 2010 AHS Alexander Nikolsky Honorary Lectureship.

'This comprehensive book is a must-read for rotorcraft students and researchers and practising engineers. This fascinating classic provides a fresh look at many complex rotary-wing phenomena.' Inderjit Chopra, Journal of the American Helicopter Society
