The invention discloses a helicopter tail rotor wing with a detachable structure and a production process thereof.The helicopter tail rotor wing with the detachable structure comprises a fuselage, a tail rotor body is fixed to the tail of the fuselage, a detachable assembly is fixed to the top of the tail rotor body, and the detachable assembly comprises a rotating shaft; the bottom end of the rotating shaft is fixed to the output end of an external motor, a rotating inner ring is fixed to the outer surface of the rotating shaft, a rotating inner ring is fixed to the outer surface of the rotating inner ring, a propeller hub is fixed to the top end of the outer surface of the rotating shaft, a plurality of connecting plates which are annularly and evenly distributed are arranged on the outer surface of the propeller hub, and connecting blocks are arranged at the ends, away from the propeller hub, of the connecting plates. The connecting block is fixedly connected with the connecting plate through a bolt; through hot isostatic pressing sintering and heat treatment, combination of the carbon fibers and the titanium alloy is promoted, stress concentration is eliminated, the load transmission effect of the carbon fibers is brought into full play, and the mechanical property of the carbon fiber reinforced titanium alloy composite material is improved.

    本发明公开了一种带有拆卸结构的直升机尾旋翼及其生产工艺,该带有拆卸结构的直升机尾旋翼,包括机身,所述机身的尾部固定有尾旋翼本体,尾旋翼本体的顶部固定有可拆卸组件,可拆卸组件包括转动轴,转动轴的底端与外界电机的输出端相固定,转动轴的外表面固定有转动内圈,转动内圈的外表面固定有转动内圈,转动轴的外表面顶端固定有桨毂,桨毂的外表面设有若干呈环形均匀分布的连接板,连接板远离桨毂的一端设有连接块,连接块与连接板之间通过螺栓固定连接;本发明通过热等静压烧结和热处理,促进碳纤维与钛合金的结合,消除了应力集中,有利于充分发挥碳纤维的载荷传递作用,使碳纤维增强钛合金复合材料的力学性能得到提升。
