  • Aircraft wing, aircraft wing composite material, and method of manufacture thereof
    Patent number: 7802759
    Abstract: To provide an aircraft wing which has both high bending flexibility in the wing chord direction and high capacity to maintain the wing shape in the wing span direction, and to which morphing aircraft technology can be applied in the high-speed regime where aerodynamic forces are high. The wing is formed by arranging a plurality of CFRP rods having maximum anisotropic stiffness in the axial direction, so as to be parallel to the wing span direction, and filling the gaps between the CFRP rods with an elastic material.
    Type: Grant
    Filed: December 12, 2005
    Date of Patent: September 28, 2010
    Assignee: Japan Aerospace Exploration Agency
