The Effect of Elasticity on the Lifting Force of a Wing,
Abstract
A deformable bearing surface is of interest from the standpoint of designing rigid structures and obtaining controllable aerohydrodynamic characteristics. In the article static aerohydroelasticity is investigated. A general equation is considered for the deformation of the bearing surface in an ideal noncompressible infinite stream. The elastically deformed load-bearing surface is investigated by assuming that the theory for the large aspect ratio airfoil is applicable. An integral-differential equation is obtained for an elastic airfoil. The solution of this equation gives a dependence for the lift coefficient of a nondeformable airfoil and the function for the effect of elasticity. (Author)
