The invention discloses an air rudder and an aircraft, and relates to the technical field of aircrafts, the air rudder comprises an integrated rudder body, a rudder leading edge and a thermal barrier coating, the integrated rudder body comprises a rudder frame, a rudder shaft and a rib connected with the rudder frame, and a rudder surface wrapping the rudder frame and the rib, and the integrated rudder body is configured to be formed through 3D printing; the rudder leading edge is installed at the front end of the rudder frame, and the control surface is coated with the thermal barrier coating. The rudder body is formed through 3D printing, mechanical connection between a rudder shaft and a rudder surface in a traditional air rudder is omitted, the risk that the air rudder is overheated and large in deformation amount and finally breaks down due to mechanical connection between the rudder shaft and the rudder surface along with the increase of the speed of an aircraft is improved, and the integrated rudder body can bear higher force loads and thermal loads under the flight working condition; it is ensured that the front edge of the rudder meets the requirement for bearing heat flow scouring, the short-time 1000 DEG C heat protection performance and the long-time 600 DEG C heat protection performance can be achieved through the thermal barrier coating, and the air rudder provided by the invention guarantees the bearing capacity and the heat protection capacity under the condition that the requirement for light weight is met.

    本发明公开一种空气舵及飞行器,涉及飞行器技术领域,包括一体化舵体、舵前缘和热障涂层,一体化舵体包括舵框架、与舵框架连接的舵轴和筋条以及包覆在舵框架和筋条外的舵面,一体化舵体被配置为3D打印成型,舵前缘安装于舵框架的前端,热障涂层覆设于舵面。舵体采用3D打印成型,取消了传统空气舵中舵轴与舵面的机械连接,改善了随着飞行器速度提高由于舵轴与舵面机械连接而致使空气舵过热与变形量大最终发生故障的风险,一体化舵体能够承受飞行工况下的更高的力载荷和热载荷,确保舵前缘满足承受热流冲刷的要求,通过热障涂层能够实现短时1000℃以及长时600℃防热性能,本申请提供空气舵在满足轻量化的要求下保证了其承载能力和防热能力。
