TRENDS IN MODERN AIRCRAFT STRUCTURAL DESIGN

Although the Electra structure is based on past good practice, its higher performance and use of prop-jet engines have injected certain new situations of interest to structural engineers. Such items include the new CAA gust criteria, loads created by prop-jet engine failure, development of the “No-Hazard” windshield, engine nacelle design loads, wing loads when taxiing with full wing fuel, fail safe and fatigue, the use of large die forgings, and the bleed air duct system used for de-icing.
