The invention discloses a lattice composite structure thermal protection air rudder for a high-speed aircraft and a manufacturing method, and the manufacturing method comprises the steps: 1, according to the thermal environment conditions and load conditions of the aircraft and the response characteristic requirements of the air rudder, a rudder shaft and a control surface of a metal framework are determined, the rudder shaft adopts a solid structure, and the control surface adopts a lattice structure; 2, according to the thermal environment condition of the aircraft, in combination with the temperature resistance of the metal framework, a composite material heat-proof structure is determined, and the control surface is coated with the composite material heat-proof structure, and the lattice structure is completely filled with the composite material heat-proof structure; 3, a metal framework is manufactured through a selective laser melting additive manufacturing process; and 4, the composite material heat-proof structure is manufactured through a resin transfer molding forming technology or an integrated mold pressing technology. The problem that a traditional air rudder is limited in the aspects of weight, structural efficiency, heat conduction management and the like is solved.

    一种面向高速飞行器的点阵复合结构热防护空气舵及制造方法,制造方法包括:步骤1:根据飞行器热环境条件、载荷条件以及空气舵的响应特性要求,确定金属骨架的舵轴和舵面,舵轴采用实体结构,舵面采用点阵结构;步骤2:根据飞行器热环境条件,结合金属骨架的耐温性能,确定复合材料防热结构,复合材料防热结构包覆舵面且完全填充点阵结构;步骤3:采用激光选区熔化增材制造工艺制造金属骨架;步骤4:采用树脂传递模塑成型工艺或一体化模压工艺制造复合材料防热结构。本发明解决了传统空气舵在重量、结构效率和热传导管理等方面的局限性问题。
