Abstract:

The report summarises the fully documented experimental data which is available on the stresses induced in typical aircraft structure by jet noise at take off. The experimental values are compared with a design procedure based on a single degree of freedom analysis and the method is extended for application to control surfaces and to integrally stiffened skin panels. The estimates are generally within a factor of two of the measured values. The relatively new phenomenon of shock cell noise is introduced and a typical result for the variation of r.m.s. stress during take off and climb is discussed.
