Abstract: An airplane wing assembly includes a wing, a winglet and a connection element. The wing has a wing box. The wing box is located at a wing tip of the wing and the winglet is connected with the wing by the wing box. The connection element includes a butt joint rib, which is assembled with the wing box, and a center connection, which is assembled with the winglet. The butt joint rib has a first shearing pin hole and a second shearing pin hole, into which are press fitted a corresponding first and a second shearing pin respectively to form interference fit. The center connector has a first sleeve hole and a second sleeve hole.

Abstract: An apparatus for testing the gas permeability on the inward facing direction of a pre-impregnated resin matrix composite material layer includes a mold, a loading apparatus, a temperature control apparatus, a vacuuming apparatus, and a flow detecting element. A test specimen is laid flat inside the mold between airtight sealing elements that leave exposed two ends of the test specimen on the inward facing direction of the layer. An air inlet and an air outlet respectively are arranged on the mold and correspond to the two exposed ends of the test specimen. The inlet is connected to the flow detecting element, and the outlet is connected to the vacuuming apparatus. Air is forced to move in a vacuumed cavity along the inward facing direction of the layer. Testing of air permeability of pre-impregnated material in solidification technique is allowed via adjustments of pressure and temperature.

Abstract: An apparatus for testing the air permeability in the thickness direction of a resin matrix composite material layer includes a mold having a cavity and a covering plate, a loading apparatus, a temperature controlling apparatus, a vacuuming apparatus, and a flow detecting element. An air inlet is connected to the flow detecting element, and an air outlet is connected to the vacuuming apparatus. The covering plate has a through-hole with upper and lower ventilation pieces. The loading apparatus addresses the upper ventilation piece. A test specimen is laid flat between the ventilation pieces. Employment of the present invention allows for accurate testing of air permeability of pre-impregnated material in the thickness direction of the resin matrix composite material layer under different pressure and temperature conditions.
