A flight investigation has been made on a large swept-wing bomber airplane in rough air at 5,000 feet to determine the effects of wind flexibility on wing bending and shear strains. In order to evaluate the overall magnitude of the aeroelastic effects on the strains and their variation with spanwise location, amplification factors defining the ratio of the strains in rough air to the strains expected for a rigid and quasi-rigid airplane were determined.
