scope:

INTRODUCTION 

The requirements of this Chapter are concerned with:

(i) The control of flutter, divergence, ground and air resonance and allied aero-elastic and aero-mechanical self-excited phenomena.

(ii) The restriction of structural distortion of the rotors, control systems and airframe within limits that will not dangerously impair stability and control. 

Rotorcraft airframes and equipments are subjected to vibratory forcing from a number of sources. These forced response aspects of vibration are dealt with in Chapter 501. 

Compliance with the requirements shall be established by calculation or by compliance with the relevant criteria given in the Leaflets of this Chapter, supported in each case by tests. Calculations shall be discussed with and approved by the Director, RAE.
