Extract

It is indeed a great honour and a particularly pleasing experience for me to have been invited to give the 18th Lanchester Memorial Lecture. Pleasing because it enables me to recall before such a distinguished audience, one of Lanchester's outstanding achievements in the field of aircraft stability, his phugoid theory. This slow oscillation problem has often been neglected but its implications can be vital as the Vulcan crash in 1956 emphasises, and the development of STOL with high lift has forced designers to turn again to a serious consideration of the phugoid as I will show presently in the first part of this lecture.
