The invention relates to a heat-proof and load-bearing integrated air rudder thermal resistance structure, and belongs to the technical field of air rudders, the heat-proof and load-bearing integrated air rudder thermal resistance structure comprises a rudder skeleton, the rudder skeleton comprises a fork-shaped groove, reinforcing ribs arranged on the peripheral side of the fork-shaped groove, constraint protrusions arranged on the reinforcing ribs, a rudder skin and a rudder shaft, and the rudder skin covers the outer side of the rudder skeleton. The rudder shaft comprises a rudder shaft support connected with the fork-shaped groove in a matched mode and a rudder shaft column section arranged on one side of the rudder shaft support, the heat insulation sleeve and the heat insulation ring are arranged at the end, close to the rudder shaft column section, of the rudder shaft support, the peripheral side of the rudder shaft support is wrapped with the first heat insulation plate, and the second heat insulation plate is arranged on the peripheral side of the fork-shaped groove; the second heat insulation plate can be arranged on the peripheral side of the fork-shaped groove and used for reducing the temperature of the fork-shaped groove of the rudder framework, blocking heat radiation of high-temperature air in the grid ribs to the fork-shaped groove of the rudder framework, reducing heat conduction of the rudder framework to a rudder shaft and achieving the purpose of heat resistance.
本申请涉及一种防热承载一体式空气舵热阻结构,属于空气舵技术领域,防热承载一体式空气舵热阻结构,包括舵骨架,舵骨架包括叉形槽、设置于叉形槽周侧的加强筋和设置于加强筋上的约束凸起,舵蒙皮,舵蒙皮覆盖在舵骨架的外侧,舵轴,舵轴包括与叉形槽配合连接的舵轴支座和设置于舵轴支座一侧的舵轴柱段,隔热套,隔热环设置于舵轴支座靠近舵轴柱段的一端,第一隔热板,第一隔热板包裹于舵轴支座的周侧,第二隔热板,第二隔热板设置于叉形槽的周侧;本申请可以第二隔热板设置于叉形槽的周侧,用于减小舵骨架的叉形槽自身的温度,阻断网格筋内部高温空气对舵骨架的叉形槽的热辐射,减少了舵骨架向舵轴的热传导,实现热阻目的。
