The invention belongs to the field of aeronautical manufacturing, and relates to a waterproof and drainage device for a wing and an engine hanging butt joint based on 3D printing. The device comprises a drainage groove 1 and a waterproof rubber strip 2, wherein the drainage channel 1 is mounted on the side of the wing leading edge skin 3 and at the intersecting line position of the wing leading edge skin 3 and an engine hanger, and the drainage channel 1 is divided into a drainage section 101, a water diversion section 102, a leading-out section 103 and a fixed section 104; the drainage section 101 is located in a transverse area of an intersecting line, the water diversion section 102 is located in a longitudinal area, the leading-out section 103 is a leading-out pipe 11 led out from the tail end of the water diversion section 102, a water tank 8 is arranged on the drainage section 101, and a water diversion hole 10 communicated with the water tank at one end and a drainage pipe at the other end is formed in the water diversion section 102. The water tank 8 is used for receiving and collecting leaked water of the wing leading edge skin 3 and the engine hanging butt seam, guiding the leaked water to the water guide hole 10 and finally enabling the leaked water to flow out of the guide-out pipe 11; the waterproof rubber strip 2 is installed on the motor hanging side and the intersecting line position of the wing leading edge skin 3 and the engine hanging and used for sealing the butt joint of the wing leading edge skin 3 and the engine hanging under the normal condition.
本发明属于航空制造领域,涉及一种基于3D打印的机翼与发动机吊挂对接处防排水装置。该装置包括:排水槽1与防水橡胶条2;排水槽1安装在机翼前缘蒙皮3侧,机翼前缘蒙皮3与发动机吊挂的相贯线位置,排水槽1分为排水段101、引水段102、导出段103、固定段104;排水段101位于相贯线的横向区域,引水段102位于纵向区域,导出段103是引水段102末端引出的一段导出管11,排水段101上设置有水槽8,引水段102上设置有与一端水槽连通,另一端与排水管连通的引水孔10;水槽8用于接收并汇集机翼前缘蒙皮3与发动机吊挂对缝漏水,并导流到引水孔10,最终从导出管11流出;防水橡胶条2安装在动机吊挂侧,机翼前缘蒙皮3与发动机吊挂的相贯线位置,用于在正常情况下密封机翼前缘蒙皮3与发动机吊挂对缝。
