Book Description
The dynamic coupling of rigid and elastic de grees of freedom of an airplane are described by two methods. In the first, coupling is de scribed by the changes in airframe character istic equation roots caused by the introduc tion of coupling terms to the equations of mo tion. The second method employs modal response coeffients to compare the relative amplitudes of rigid and elastic degrees of freedom at each coupled mode frequency. Simple literal expres sions are obtained for each of these descrip tors and physical interpretations given. Time vector diagrams are also used to show the major parameters affecting coupling.
