Abstract
High-performance aircraft experience severe acoustic loads and consequently suffer from acoustic fatigue cracking in service. Although adhesively bonded repairs have been implemented quite successfully in a variety of aircraft applications for the past twenty years, a recent application to repair acoustic-fatigue cracking on the engine nacelle of the F/A-18 has proved ineffective [1], contrary to expectations from current design practice for such repairs. Accordingly, an extensive research program is in progress, aimed at (i) an improved repair-design analysis that addresses the limitations of conventional repair design in the present context; (ii) modelling and optimisation of passive and active damping treatments in conjunction with bonded repair; (iii) laboratory and flight-test evaluation of optimised repair and damping schemes.
