The invention provides a foldable aerial rudder of a hypersonic aircraft. The foldable aerial rudder comprises a rudder surface assembly, a tiller assembly and a rudder surface fixing assembly. The control surface fixing assembly is rotatably connected with the tiller assembly through a transmission shaft, the control surface assembly is provided with a radial locking structure, the control surface fixing assembly is provided with an axial locking structure, and the radial locking structure and the axial locking structure are matched with a radial locking hole and an axial locking hole in the tiller assembly, so that the control surface assembly is locked in multiple directions at the same time after being automatically unfolded; the strength of the joint after the control surface assembly is unfolded is obviously improved; modular design is adopted, assembling is convenient, the transmission shaft and the torsional spring structure are designed in the air rudder, the overall structure is compact, and the sealing performance is good; the control surface assembly, the tiller assembly and the control surface fixing assembly are each provided with a heat-proof layer, the influence of aerodynamic heat on the internal structure in the hypersonic flight process can be effectively reduced, the stability, reliability and track precision of the aircraft in the flight process are improved, and the hypersonic stable flight requirement in the high-temperature and large-overload environment is met.

    本申请提供一种高超声速飞行器可折叠空气舵,包括舵面组件、舵柄组件、舵面固定组件。舵面固定组件通过传动轴与舵柄组件可转动连接,舵面组件设有径向锁紧结构,舵面固定组件设有轴向锁紧结构,配合舵柄组件上的径向锁紧孔、轴向锁紧孔,使舵面组件在自动展开后从多个方向同时锁紧,显著提高了舵面组件展开后连接处的强度;本申请采用模块化设计,便于装配,将传动轴及扭簧结构设计在空气舵内部,整体结构紧凑,密封性好;舵面组件、舵柄组件及舵面固定组件均设有防热层,可有效降低在高超声速飞行过程中气动热对内部结构的影响,提高飞行器在飞行过程中的稳定性、可靠性及轨迹精度,满足在高温大过载环境中高超声速稳定飞行要求。
