Abstract
An outlet guide vane includes an aerofoil body including a root, a tip, a leading edge extending between the root and the tip, a trailing edge opposite to the leading edge, a pressure surface extending between the leading edge and trailing edge, and a suction surface extending between the leading edge and trailing edge opposite to the pressure surface. The outlet guide vane further includes a flexible membrane disposed along the pressure surface and/or the suction surface of the aerofoil body, such that the flexible membrane at least partially forms an outer surface of the outlet guide vane. The aerofoil body has a first modulus of elasticity and the flexible membrane has a second modulus of elasticity, wherein the first modulus of elasticity of the aerofoil body is greater than the second modulus of elasticity of the flexible membrane by a factor of at least 2.
