  • 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 years ago....

  • 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....

  • This little book is meant for those who have never read any Welsh history before. It is not taken for granted that the reader knows either Latin or Welsh. A fuller outline may be read in The Story of Wales, in the "Story of the Nations" series; and a still fuller one in The Welsh People of Rhys and Brynmor Jones. Of fairly small and cheap books in various periods I may mention Rhys' Celtic Britain, Owen Rhoscomyl's Flame Bearers of Welsh History, Henry Owen's Gerald the Welshman, Bradley's Owen Glendower, Newell's Welsh Church, and Rees Protestant Non- conformity...
