The paper describes new method for aeroelasticity analysis of aircraft with laminar wings in transonic flight regime. Performed studies have shown, on the example of modern transport aircraft that interaction of flow viscosity, structure elasticity and boundary layer transition influences significantly on aeroelasticity characteristics of laminar wings.
