IN a previous paper, attention was called to the general behaviour of the vibratory system comprising the aeroplane‐engine‐airscrew combination. Types of vibration frequently encountered were described and a brief resumé of damping, excitation, and natural frequency effects was given. It is the purpose of this paper to review the general problem in light of current practice and to discuss in some detail certain observations made in the course of experimental study of the complete problem.
