Extract

The present investigation fills a gap in the applications of the formal methods of rigid dynamics to the study of the motions of aeroplanes.

The principal methods for the approximate solution of dynamical problems together with their aeronautical applications may perhaps be conveniently classified as follows:—

Rigid Dynamics.Aeronautics.
1. Small oscillations about a state of steady motion and applications to stability.The longitudinal and lateral inherent stability of an aeroplane.
2. Steady motion in a circle.Steering of aeroplanes
3. Initial and impulsive changes of motion under given forces.Effect of sudden wind disturbances on an aeroplane.

It will be seen that this order of development, which was contemplated by me long before the realisation of artificial flight, was that required at that time to answer the questions, whether an aeroplane could fly without upsetting, how it could be steered in a curve, and how it could be adapted for use in boisterous weather.
