Abstract
This report deals with a study of the effect of aerodynamic lag on the bending response of wings in supersonic flow. The possibility of approximately representing the lag function by simple functions, which facilitate aeroelastic analysis, has also been examined. Laplace transform techniques are used for obtaining the response solution and the method is quite general and applicable to any Mach number. Numerical results have, however, been obtained for a particular Mach number of 1.2, as an example, and for various values of inertia and frequency parameters. The results show that the lag is important in response13; to calculations, which may be used for estimating transient loads due to gusts or manoeuvres. The results also show that the approximate representation of the lag is satisfactory and may be used for engineering applications, in the range of parameters considered.
