The invention discloses a high-bearing heat prevention and insulation integrated control surface structure, and belongs to the technical field of aircraft control surface structures. The control surface structure solves the problem that a control surface structure in the prior art is difficult to meet the comprehensive performance requirements of high bearing and heat prevention and insulation at the same time. The device specifically comprises a metal control surface, and a first heat-proof skin and a second heat-proof skin are arranged on the two sides of the metal control surface respectively; a first heat insulation skin is arranged between the metal control surface and the first heat protection skin, and a second heat insulation skin is arranged between the metal control surface and the second heat protection skin; the front end of the metal control surface is connected with a front edge assembly. According to the invention, the metal control surface is used as a main force bearing structure of the control surface structure, so that the overall bearing capacity and stability of the control surface structure can be enhanced; two sides of the metal control surface are respectively provided with two heat-proof skins for protection, so that the phenomena of thermal expansion, thermal fatigue and the like of the metal control surface in a high-speed flight or high-temperature environment are avoided; and the problems of connecting piece failure and structural damage caused by deformation difference after the metal material and the heat-proof skin material are heated are also prevented.
本发明公开了一种高承载防隔热一体化舵面结构,属于飞行器舵面结构技术领域;解决了现有技术中的舵面结构难以同时满足高承载和防隔热的综合性能需求的问题。具体包括金属舵面,金属舵面的两侧分别设有第一防热蒙皮和第二防热蒙皮;金属舵面和第一防热蒙皮之间设有第一隔热蒙皮,金属舵面和第二防热蒙皮之间设有第二隔热蒙皮;金属舵面的前端连接有前缘组件。本发明中,金属舵面作为舵面结构主要的承力结构,能增强舵面结构整体的承载能力及稳定性;金属舵面两侧分别设置两个防热蒙皮进行防护,避免金属舵面在高速飞行或高温环境中出现热膨胀、热疲劳等现象;也防止了金属材料与防热蒙皮材料受热后形变差异带来的连接件失效及结构损坏的问题。
