Wing twist and camber for the rolling maneuver of a flexible wing without aileron

摘要

A technique of using elastic wing twist and camber to achieve a specified roll rate at all dynamic pressures is examined. ^Rather than using an aileron system for roll, antisymmetric elastic twist and camber is determined to achieve the required rolling moment for a specified roll rate. ^The elastic twist and camber is achieved by providing control forces obtained from a technique referred to as fictitious control surfaces (FCS). ^To simulate twist and camber, an aerodynamic panel is modeled as a control surface rotated such that the rotation is equal to the angle of attack of the panel midpoint for a prescribed twist and camber distribution. ^Here, a full-scale realistic wing is considered for the assessment of strain energy as a measure of the necessary power required to produce the antisymmetric twist and camber deformation to achieve the required roll performance. ^Subsonic and supersonic design conditions are investigated. ^(Author)
