Abstract
There has been much recent interest in new aircraft configurations to enable improved fuel efficiency. The concept of using flared folding wingtips (FFWT) to enable increased wing aspect ratios, whilst fitting airport gate restrictions, reducing gust/turbulence loads and improving roll performance, has shown encouraging results over the past 8 years. This paper considers a different loading case - the response of a flight mechanics aeroelastic model of a commercial aircraft with FFWT to a range of lateral "one minus cosine" gusts with different lengths. Comparisons are made between the locked and floating FFWT configuration responses and it is shown that the FFWT provides improved performance through alleviation of the deflections (and by implication the loads) but has little effect on the overall flight mechanics responses.
