The introduction of the technology for bonded composite repairs of metallic
airframe structures could not have come at a more opportune time. Today, many
countries are facing the challenge of aging aircraft in their inventories. These
airframes are degrading due to damage from fatigue cracking and corrosion.
Repair with dependable techniques to restore their structural integrity is
mandatory. The concept of using bonded composite materials as a means to
maintain aging metallic aircraft was instituted in Australia approximately thirty
Acoustic fatigue is due to a very high intensity excitation as a result of pressure
waves caused by either engine or aerodynamic effects. Acoustically-induced
cracking has occurred on the external surface of the lower nacelle and aft fuselage
skins on the F/A-18, as illustrated in Figure 19.1. In the former region, overall
sound pressure levels greater than 170dB have been measured in flight [l]. These
high sound pressure levels appear to be a result of an aerodynamic disturbance at
the inlet lip....
The events recounted in this book group themselves in the main about a single figure, that of Count
Frontenac, the most remarkable man who ever represented the crown of France in the New World. From
strangely unpromising beginnings, he grew with every emergency, and rose equal to every crisis. His whole
career was one of conflict, sometimes petty and personal, sometimes of momentous consequence, involving
the question of national ascendancy on this continent. Now that this question is put at rest for ever, it is hard to
conceive, the anxiety which it wakened in our forefathers.
