View source for Aeroelastic tailoring

'''Aeroelastic tailoring''' is defined as "the embodiment of directional stiffness into an aircraft structural design to control [[Aeroelasticity|aeroelastic deformation]], static or dynamic, in such a fashion as to affect the aerodynamic and structural performance of that aircraft in a beneficial way",<ref name=Shirk>Shirk, M., Hertz, T., Weisshaar, T., "Aeroelastic Tailoring – Theory, Practice, Promise", ''Journal of Aircraft'', Vol. 23, No. 1, pp. 6-18, 1986.</ref> or "passive aeroelastic control".<ref name=Weisshaar>Weisshaar, T., ''Aircraft Aeroelastic Design and Analysis'', 1995</ref> Objectives associated with aeroelastic tailoring include weight minimization, flutter, divergence, stress, roll reversal, control effectiveness, lift, drag, skin buckling, and fatigue.<ref name=NASA>{{cite web |last1=Jutte |first1=Christine |last2=Stanford |first2=Bret K. |title=Aeroelastic Tailoring of Transport Aircraft Wings: State-of-the-Art and Potential Enabling Technologies |url=https://ntrs.nasa.gov/citations/20140006404 |access-date=19 December 2021 |language=en |date=1 April 2014}} {{PD-notice}}</ref>
== History ==
According to Shirk et al.,<ref name=Shirk/> the first record of aeroelastic tailoring is from 1949 by Munk,<ref>Munk, M., "Propeller Containing Diagonally Disposed Fibrous Material," U.S. Patent 2,484,308,1111, Oct. 1949.</ref> who oriented the grain of his wooden propeller blade to create desirable deformation couplings when operated. In the late 1960s, there was a thrust in aeroelastic tailoring research, which has continued fairly steadily through to today. The forward swept wings of the [[X-29]] and the [[Active Aeroelastic Wing]] are two aeroelastic tailoring examples highlighted by Weisshaar.<ref name=Weisshaar/> Today the use of composite materials is becoming more prevalent in transport aircraft, including the [[Boeing 787]], the [[Airbus A380]], and the upcoming [[Airbus A350]]. Enhanced fabrication processes for composite laminates offer new design possibilities that have not been fully exploited for optimal aeroelastic performance and weight savings.<ref name=NASA/>
