Extract

An appropriate introduction to the topic of this lecture is the following comment taken from Cierva's third and last lecture presented before this Society in 1935:

“Perhaps the most irritating of the secondary difficulties met with in the Autogiro development have been those of a dynamical nature. The dissymmetry of speed on both sides of the rotor produces periodical variations in the lift and drag…“

The Fourth Cierva Memorial Lecture, which it is my privilege to present, is concerned with these periodic variations and their contribution to what remains one of the most irritating problems in rotary wing design.
