Extract

The problem of the vibrations induced in an aircraft structure excited by jet noise has been solved mathematically in general terms by Powell and others. The most promising methods for dealing with a practical structure are those based on the normal mode approach. In these methods the response of the structure in each of its normal modes is first determined and then the total response is obtained by a summation of individual responses. Use of these methods on practical structures is tedious because of the large number of modes which must be considered and also the difficulty of calculating theoretically the normal modes of a practical stiffened structure.
